Abstract
MEMS devices such as Pressure sensors, Accelerators, RF-MEMS, Microphones, Bio-MEMS, Printer heads, etc. are very sensitive and hence require gentle die singulation technique. Such technique needs to be very clean, not generating any particles, preventing mechanical stress, vibrations, or ESD damages, and in particular, it should work without any cooling fluids. As well known from conventional diamond blade dicing all these influences may damage fragile mechanical MEMS structures like membranes, micro holes or sensitive chemical coatings. In contrast to blade dicing and other ablation laser techniques, the “ML laser technology” is using a low energy IR laser beam that is focussing into the Silicon bulk. Hereby a so called modification layer with defined punctual stress profile is generated that works effectively as a hyphenation point. The die separation itself takes place by subsequent dicing tape expansion. Since only a very limited interior region of the wafer is processed by laser beam irradiation, mechanical or thermal damages and die edge chipping can be avoided. Latest ML dicing machine generation and its accessory tools combines fully automatic operation, superior die separation quality with high productivity. The latter is achieved by a newly developed multi-beam laser engine that is built on a high speed machine platform allowing dicing feed speeds up to 1000mm per second. The presentation provides an overview about typical MEMS applications for the ML singulation process, its requirements and limitations, as well as about laser dicing process variants like double side laser irradiation of MEMS wafer stacks and laser irradiation through tape (LTT).

Abstract
The concept of MEMS sensor testing has evolved from a fantasy to a reality over the last two decades. What was once considered impossible in high volume manufacture has now become mainstream in the industry. Initially, MEMS sensor devices were introduced as an alternative to bulky technologies, with lower performances than their predecessors. However, today's MEMS devices with proven reliability and performances have surpassed their predecessors and are competing with their high-cost and high-end counterparts. Examples of such MEMS sensor devices can be seen in the MEMS microphones whose early specifications started off as a simple audio transducer, now has morphed into high-fidelity MEMS device, competing with the high-end studio microphones. Testing such “high-performance” MEMS sensor devices in high volumes at the lowest possible costs with little or no compromises calls for an innovative combination of test techniques and close cooperation between the OSAT and the MEMS design engineers, product engineers and the applications engineers. Areas that are often overlooked are, the form factor of the device under test, the use of test techniques that can provide a higher throughput than electrical testing and the final end application. The ability to include self-test and self-calibration structures into the design will reduce the test burden. The main challenge faced during MEMS sensor test is in the stimulus development, while the electrical testing can be easily accomplished by a low-end tester. When creating MEMS test specifications, a careful balance needs to be drawn between too much and too little test coverage. This keynote focuses on the evolution, challenges, and opportunities for MEMS sensor testing spanning the yesterdays, today and will provide a vision for the future of lower cost MEMS sensor test.

Flexo printing and selective sintering of metal based inks on paper – Optimization of RFID-HF loops for mass production

Thénot, Victor

Abstract
This work examines the potential of paper for the production of printed NFC tags. Paper characterization demonstrates high temperature tolerance and very low roughness enabling the electrical performance of conductive inks to be fully developed. Flexo process was considered for the printing of low-cost electronic devices. Moreover, the electrical performances of silver based inks are studied according to the size of their particles. Indeed, the use of metal nanoparticles can facilitate the activation of atomic diffusion mechanisms. In parallel, microparticles are cheaper. In any case, the coalescence of the metal particles after printing cannot be initiated without a thermal sintering treatment. Sintering is usually carried out in an oven, temperature must therefore remain below the tolerance of the substrate. This leads to limited electrical performances for long duration. To fit with industrial constraints of large-scale production and to achieve the best electrical performance in a short time, deployment of emerging near-infrared (NIR) and intense pulsed light (IPL) photonic technologies is considered. These latter are based on the absorption of light energy by the ink thus causing rapid heating. The important absorption differential between the inks and the substrate allows high heating selectivity which makes it possible to limit the degradation of the substrate while the ink temperatures may be greater than 300 ° C. For each sintering process, the influence of the various parameters on the final electrical performance has been studied by using an in-situ resistance monitoring, allowing sampling frequency up to 250 kHz. Finally, RFID-HF loops were printed, sintered and characterized while an estimate of the production costs was carried out. The obtained results demonstrate the potential of paper, coupled with flexographic roll-to-roll process and NIR technology, enabling the large-scale production of RFID-HF tags at a material cost of the order of 5 euros cents.

Abstract
Difficult though it is to believe, the small, micro, even nano computers we encounter every day are the direct descendants of the von Neumann architecture described in 1945, which gave birth to the general-purpose computing model, and created the software revolution. Future architectures will disaggregate monolithic components like general purpose CPUs, operating systems and middleware, providing the required insertion points, adding flexibility and improving security. Quantum computing will inevitably be delivered with a mixture of general purpose CPUs, Quantum hardware and other accelerators, which will enable application developers to restructure their applications to benefit from the distinct capabilities of each specialized element. But, computing will no longer be restricted to traditional platforms, but will be embedded in almost everything, and interconnected in a way that establishes an unprecedented Computing Continuum. A plethora of sensors, actuators, robots, drones, cars etc. will not just act standalone. They will be part of an all pervading, interconnected network that exhibits enormous complexity, particularly at the ‘edge’ of the ecosystem, creating a cognitive loop. It is driving to the emergence of Swarm Intelligence where the individual computing capacity of the devices at the edge will be complemented and supplemented by their dynamic cooperation with other objects in swarm communities acting as an intelligent whole. It perfectly fits the emergence of the networked connection of people, process, data and things that is exploding, pushed by business models, for which current architectures will not work anymore.

Abstract
The presentation will show benefits and feasibility results for electroless plating of different ternary nickel alloys in comparison to the standard electroless phosphorous-containing nickel for packaging in growing power electronics or automotive industry. Standard electroless phosphorous-containing nickel for ENEP* or ENEPIG** under bump metallization has the disadvantage that at temperatures above 350°C a phase transition occurs which leads to a layer stress change and may cause cracks in the under bump layer. Ternary nickel alloys reveal no phase transitions up to 600°C, and are an excellent alternative to the standard electroless medium or high phosphorous-containing nickel for high temperature processing post nickel deposition, and high temperature soldering or applications. The paper will showcase results of the advanced properties of three different electroless ternary nickel alloys in comparison to a standard medium phosphor and a low phosphor nickel, with regards to thermal behavior, stress shift, and facture toughness. *electroless nickel, electroless palladium ** electroless nickel, electroless palladium, immersion gold

Abstract
Redistribution layers are essential to a variety of packaging technologies, as it is with more RDLs that I/O density is increased. Increasing the I/O count allows for more complex, high speed die to be packaged and supports improved reliability performance. Next generation devices for FOWLP require decreasing the RDL pitch down to 2x2µm. Successful formation and plating of such fine features, however, pose a challenge for both suppliers and manufacturers, with the primary plating challenge being the simultaneous plating of ultra fine L/S, large Cu pads, and filling of microvias with a deposition rate that optimizes throughput. Additionally, the mechanical properties and impurity requirements for the Cu deposition become more difficult to control and optimize with sub 10µm L/S: 1) (large) optimum grain size, polygonal Cu crystal structure for high (ductility) mechanical strength and low resistivity which impacts electrical performance; 2) low internal stress for minimized wafer warpage and good adhesion – both of which impact yield; and 3) low organic co-deposition for minimized micro voiding. Electroplating with standard Cu electrolytes results in micro voiding that amass after thermal cycle testing and may lead to failures or breakages in the Cu metal lines. To overcome this, the bath conditions, additives, and current density should be adjusted to optimize their influence on the deposit properties in terms of impurities and grain size. This paper will discuss how the mechanical properties of Cu can enable higher reliability, and will present plating results achieved with a new electrolyte.

Abstract
Abstract Research activities in the field of brain-inspired computing have gained a large momentum in recent years. The main reason is the attempt to go beyond the limitation of the conventional Von Neumann architecture that is in-creasingly affected by the limitation of the bandwidth and latency of the memory-logic communication. In neuro-morphic architectures, the memory is distributed and can be co-localised with the logic, in particular it is what the new resistive memories technologies could provide. While most of the attention is being directed to implementation of Deep Learning algorithms in large computing system, the impact on device and circuit technology has been mixed. On one hand, advanced standard CMOS technology has been used to develop GPU and specific circuit accelerators without making use of any “bio-inspired” hardware. On the other hand, emerging resistive memory devices (RRAMs) are considered good candidates to emulate a biologically plausible synaptic behavior at nanometer scale, because of the fact that they offer the possibility to modulate their conductance by applying low biases, and can be easily integrated with CMOS-based neuron circuits in a back-end process during the making of the chip. This has opened the way for the realization of compact and energy-efficient computing architectures based on artificial neural networks (ANNs) – mainly using unsupervised learning rules such as the Spike Timing Dependent Plasticity - but that have been restricted mostly to the research community due to the insufficient maturity of the technology. An intermediate, and probably faster to market application of these new memory technologies will be their applica-tion as a slow-nonvolatile cache/fast mass storage as inter-mediate memory level in conventional accelerators. This will allow a reduction of the fast DRAM and SRAM cache areas while still reducing latency to access the mass storage.

Abstract
The explosive growth of information exchange requires scalable, high-yield and cost-effective integration of microsystems. Silicon photonics is becoming a technology of choice for optical communications. Compatibility with cmos manufacturing process is one key of success since it allows taking advantage of the production capacities of foundries; i.e. big volume and low cost manufacturability [1-2]. Integration of high performances devices is the key of success for these platforms. Today, many silicon platforms are available in foundry with similar device offer aiming to address at least 25 Gb/s applications. CEA-Leti has developed such base line silicon photonic technology with demonstrated results for 50 Gb/s data rate. New technological challenges are explored to improve the capacities of this platform by developing new integration schemes such as multilevel silicon, integration of a silicon nitride level on top of the silicon or heterogeneous materials and specific edge coupling processing. We are presenting here results on 3 add-on developed on our silicon photonic platform: • silicon nitride and hybrid silicon nitride on silicon device • Hybrid III-V on silicon laser • 3D packaging

Abstract
The advent of the IoT has put the device on the centerstage of security-related debates. Attacks on the device itself can have a severe impact on the provided services (e.g. attacks on the Philips Hue lamp). Conversely, the device can be an attack entry door for the entire system (e.g. the connected cameras used making a D-DoS on DNS servers). Protecting the device does not only mean that we need to protect the way the device is architectured, the way the embedded applications are implemented but also the way the device is manufactured and packaged. In this presentation, we shall first introduce the underlying hardware security issues before focusing on physical attacks like reverse-engineering, side channel analysis and fault attacks. We shall then explain how some of those issues can be addressed with a secure packaging. We shall provide an overview of existing secure packaging technologies and conclude on the remaining challenges for innovative secure packaging solutions.

Abstract
In this paper we present the results of a study into the successful development of wireless flexible sensor circuits for embedding into carbon fibre composite materials. There is significant interest in many industrial sectors in the use of ultra-thin and flexible sensor circuits for structural health monitoring as well as process and environmental monitoring. The challenges of this requirement include (inter alia) the provision of power to the embedded circuits, the accessing of sensor measurements and the impact of the sensors on the structural integrity of the composite. Development work at the Centre for Process Innovation and the National Composites Centre in the UK has created a number of hybrid flexible circuits which utilise a printed strain gauge and COTS solid state components to monitor strain within a carbon fibre composite. The circuits developed use inductive power transfer combined with RF communications to provide measurement of strain and this could be extended to include other structural parameters such as pressure and temperature. Demonstrator circuits have been assembled into carbon fibre composites and power and data transfer functionality have been successfully demonstrated. The results of the testing of these assemblies will be presented. Mechanical stress testing of the assembled circuits has been performed and the results show that the effect of the embedded circuit is measureable but this can be mitigated by careful selection of the approach to integration. This work has shown that the embedding of wireless sensor circuits within carbon fibre composites is possible providing embedded sensor capability for a wide range of applications.

Abstract
Wide Band Gap (WBG) semiconductors such as SiC, GaN, diamond and recently Ga2O3 show superior material properties, which allow operation at high switching speed, high voltage and high temperature, enabling lower conversion losses and smaller converter volumes. Driven by these superior properties and propelled by new volume markets like Electrical Vehicles (EV), WBG semiconductors are today at the doorstep from niche to mainstream. SiC is considered the most advanced WBG semiconductor for power, with main application in the medium to high voltage range (> 600V) followed by GaN with good potential in medium voltage range (< 600V). The success of SiC comes also from its generally high compatibility with Si manufacturing technology and Si production lines. However, due to the different physical and chemical properties of SiC, process steps have to be adjusted. For a few process steps, the requirements are so different that they are out of scope for standard Si tools and require special new tools. For instance, for superior thermal gate oxide formation, temperatures up to 1500°C along with NO gas annealing capability are desirable and for dopant activation in SiC, even temperatures up to 2000°C are required. The presentation will mainly touch on SiC specific technology aspects related to dopant activation and thermal gate oxide formation followed by a brief introduction of centrotherm´s SiC dedicated tool set.

Abstract
Consumer demand and competitive pressure have pushed automotive manufacturers to build greater intelligence into automobiles and trucks. For example, the Chevy Volt uses nearly 100 microprocessors running about 10 million lines of code in total, placing the Chevy Volt's software content close to that of the Boeing 787 Dreamliner. As with that electric vehicle, mainstream automotive design is increasingly relying on more sophisticated electronic systems. Indeed, advances in automotive technology revolve around five key trend: • Advanced Driver Assistance System (ADAS) and autonomous driving • Advanced Motor Control • Engine/Energy Management Systems • Graphical Interfaces and entertainment • Vehicle System of Systems in the Internet of Things These growing trends require new advanced packages which had not been used to such an extent in harsh automotive environment in the past, e.g. combination of dedicated vision processors, multicore CPUs and vision software. For motor control new MCU and FPGA Solutions, for IOT, new combo MEMS, 5G for wireless external connectivity and extended bus systems for internal subsystem links. Most of these developments were possible by integrating more and more functionality into one package and maintaining the stringent automotive safety and reliability requirements. New Backend test and handling systems had to be developed to address the new package requirements to ensure robust functionality. This breakthrough technology provides: • the lowest CoT for High Volume Manufacturing • Tri-temp for WLP, Fan-out and other small and mid-size packages including vision inspection • Stimuli for Combo MEMS • Fine pitch Kelvin contacting

The semiconductor industry has established integrated design environments based on PDKs (Process Design Kits), standard cell libraries, memory architectures, and IP. This design infrastructure is a key success factor, providing easy access to CMOS technology for IC designers, and increasing the chance of first-pass successful silicon. Can these features and benefits be brought to MEMS product designers? MEMS-based component suppliers want to reduce their time to market and rapidly ramp their designs into high-volume production, by reducing design spins and fabrication cycles. At the same time, a new MEMS design often requires process development not typical in CMOS design. While the prior MEMS rule “one process, one product” has become weaker over the last few years, MEMS design tools must still be very much “process aware” and adaptable to process modifications. Ideally, a design environment and design methodology for MEMS should enable efficient re-use of technology and design knowledge while supporting manufacturing process changes and design optimization. We will present a new methodology for MEMS design that uses MEMS Process Design Kits. These PDKs can be the “golden” container for MEMS technology and design information, and increase the chance for first-pass successful silicon. Based upon proven technologies from X-FAB and CEA Leti, we will share examples of MEMS component libraries that contain multi-physics compact models (rigid or flexible shapes for masses and membranes, electrostatic combs, piezo resistive gauges, suspension beams) and demonstrate how these models and libraries enable the reuse of characterized structures across multiple designs. We will then demonstrate how a parameterized and interactive component library, combined with a MEMS PDK interface, can facilitate the adaptation to foundry specific processes, provide designers with the ability to quickly explore a broad design space, and optimize designs for performance and manufacturing.

Abstract
Paper electronics has emerged as a game-changing platform for future applications in display, healthcare, and environmental monitoring devices. The low-cost of paper combined with scalable manufacturability of printing technologies of electronic devices will allow production of a trillion of systems for IoT. Due to its biodegradable and fully-recyclable properties, the paper system paves a way for low carbon footprint and less environmental damages. The technical challenge in the paper electronics lies in the printing of electronic devices. Organic and metal-oxide semiconductors can be printed at low-temperature and hence on a paper substrate. However, carrier mobility and reliability of thin-film transistors (TFTs) using those materials are still much inferior than those for silicon. Silicon as the base material, on the other hand, has advantages in terms of high-mobilities for the both of electron and holes, chemical and electrical stability, and low-power consumption by CMOS circuit configuration. The biocompatibility of silicon makes a good match with paper for the substrate. Silicon can be printed using liquid silicon ink, which is a mixture of polymerized cyclopentasilane (CPS) and a solvent]. Thermal annealing higher than 350oC of this material, however, was necessary, to convert it to solid silicon, which prevented its usage on inexpensive substrates with a limited thermal budget. In this presentation, we review a novel method that we developed for forming polycrystalline silicon (poly-Si) patterns directly on paper using the same liquid silicon with doctor-blade coating and local irradiation of excimer-laser with room temperature process. We review also the process and electrical properties of poly-Si TFTs fabricated on the paper. This technique will break-though the printed electronics by enabling applications such as fast printed electronics that are inexpensive, fully-recyclable, biodegradable and even edible.

Abstract
Textile conductive substrates are drapeable, highly flexible, and more insensitive to reversed bending fatigue compared to conventional rigid or flexible printed circuit boards. Despite this the surface mounting of microelectronic devices is not solved retaining the textile properties. Textile Circuits using conductive yarns are limited by textile patterning, printing of conductive inks often does not meet mechanical properties. Using LPKF-Laser Direct Structuring Process (LPKF-LDS) user defined circuits can be structured on the surface of special polymers, usually on injection Moulded Interconnect Devices (MID). Here textile fabrics made from LDS-polymers, the following metallization with the LDS-process, and the mounting of SMD was studied. Integrated Circuits on textile sheets preserving textile properties have been manufactured with LDS technology. For this purpose multifilament yarns have been produced by melt spinning of LDS modified polymers. These yarns have been processed to woven textile bands. These could be surface activated by laser. The activated areas could be copper plated chemically. These conductive circuits can be mounted with e.g. with SMD by soldering. In this study we could show that LDS-yarns can be produced with a special spinning process which can be processed with textile technologies. The LPKF-LDS-process can be applied to the fabric forming conductive circuit structures. The solderability and functionality of electronic parts on LDS-textiles was shown. The textile properties could be retained. The application as flexible circuit especially for the design of interfaces between hard and soft substrates shall be explored in future.

Abstract
In this paper, reliability investigation of Large Wafer Level Chip Scale package of size 54 mm2 with different die thickness and underfill conditions is discussed. Test vehicles were constructed based on the design variation using different silicon chip/die thicknesses and different underfill conditions. To assess the device reliability, extensive Board Level Reliability Temperature Cycling Tests (BLR-TCT) were carried out with a temperature load variation between -40°C till +85°C until significant solder joint fatigue failures are observed. It is evaluated that the failure mode in underfill package is different than the package without underfill. Devices with no underfill showed solder joint bulk cracks under thermal cycling condition, whereas the devices with the underfill experienced cracks on the intermetallic layer between the silicon chip and redistribution copper layer. To investigate and validate BLR-TCT reliability measurement data, Finite Element Method (FEM) simulations were carried out. Parameters like Aluminium Pad thickness and the routing method of Redistribution layer – Aluminium pad interconnection is evaluated using numerical techniques. Significant parameters were investigated in the numerical simulation model to understand the effect of package structural variation on the failure mechanism shift observed in Board level reliability (BLR) measurement tests. Results from the numerical simulation study validate the failure modes observed in BLR temperature cycling tests. Large WLCSP devices with underfill experienced a higher delamination stress on the metal interface. After design optimization study, relevant solutions have been found and illustrated. This research work can serve as a guide towards reliability assessment involved in large-scale WLCSP packages and necessary stress reduction techniques to be implemented in such smart devices.

Abstract
DISCO Corporation is a leading manufacturer for equipment and tools for wafer thinning/dicing. “Bringing science to comfortable living by Kiru (Dicing), Kezuru (Grinding) and Migaku (Polishing)” is DISCO’s mission. By combining these three core technologies, DISCO provides total solutions to meet the demanding requirements of the Semiconductor industry in terms of manufacturing thin dies with high die-strength and several new approaches for advanced packaging. A wide range of devices tend to have narrow street widths (cut margins), partially covered with low-k or ultra low-k layers in order to maximize the number of dies formed on a wafer. Furthermore, mobile and IoT consumer products incorporate an ever-increasing number of such circuit components. Quality requirements of consumer products are heading for same level as automotive products or even exceed those. In order to fulfil all these requirements, DISCO proposes several solutions focusing on avoidance of side wall cracks and interfacial layer damages. DISCO will update on latest status of Stealth Dicing, high quality laser grooving, multi beam ablation laser cutting, dicing wafers with the active side facing to the tape, applying plasma dicing and remote plasma as well as combinations of these technologies in one process flow. WLCSP and eWLB applications are facing issues in wafer thinning, as the wafers, due to consisting of resin mold and Silicon dies while having high bumps on the front side, tend to easily break when thickness becomes lower than the bump height. Nevertheless, such low thickness is required due to increasing bump thickness. DISCO offers a unique technology to grind wafers with 200 µm high bumps down to 50 µm wafer thickness. DISCO HI-TEC EUROPE GmbH, having its facilities close to Munich airport, offers certified Dicing and Grinding Production Services, so that customers can utilize most of the afore mentioned DISCO technologies in production, even without investing into DISCO equipment.

Abstract
Increased adoption of hybrid and electrical vehicles as well as renewable energy systems are driving the innovation in power module packaging. Thermal substrate, one of the major components of power modules, is not an exception, and technological advancements are necessary to meet increased reliability requirements. Herein, we show that a high-performance power electronic substrate can be designed with newly developed highly thermally conductive polyimide film to address potential issues industry strives to solve. The most widely used ceramic based substrates tend to degrade severely with prolonged thermal cycles, a typical requirement of EVs and HEVs, reducing the reliability and lifetime of the power electronic device. Also, common design of the power module requires many layers that adds thermal resistance at each bonding surface. DuPont’s new Temprion™ Organic Direct Bond Copper (ODBC) has been developed and designed to address aforementioned problems, increasing thermal durability and reliability as well as enabling system layer suppression. Temprion™ ODBC’s dielectric layer, Temprion™ DB film will absorb thermo-mechanical stress from the metals due to CTE mismatch, dramatically improving durability of the system. In addition, various kinds of metals including Cu and Al can be easily bonded to Temprion™ DB films through simple process. There are no thickness limitations on bonding metal sheets and metal attached at the bottom can be used as an integrated heat sink/baseplate. This presentation will provide an overview of the power module market, highlighting current challenges and alternative solutions to address them.

Abstract
Developments in flexible electronics technologies in application areas such as OLED displays, OPV modules, In-Mould-Structural-Electronics, HMI (Human Machine Interface) and sensors, have presented challenges to device manufacturers relating to the properties of flexible substrates. To improve yield and efficiency there is a need for materials that exhibit excellent dimensional stability and clean defect-free surfaces, and in some applications a requirement for additional functionality such as UV stability and Flame Retardancy. Proposed solutions to these issues include the use of novel co-extrusion techniques, optical modification of surfaces, and the incorporation of non-halogen flame retardant materials into a polymer matrix. Increasing interest and activity in flexible hybrid systems, foldable displays, and wearable devices, will require further modifications to substrate properties, and drive the development of flexible materials with new diverse properties and specifications. This presentation will review the latest developments in polyester film processes and technology, including an update on substrates designed for ultra-high barrier use in Displays and OPV applications, and thermoformable films for use in In-Mould-Structural-Electronics.

Abstract
Graphene and other layered 2D materials have been the focus of intense research in the last decade due to their unique physical and chemical properties. This presentation will highlight our recent progress on the synthesis and integration of 2D materials for nanoelectronics applications using atomic layer deposition (ALD). ALD is a chemical process that is based on self-limiting surface reactions and results in ultrathin films, with sub-nm control over the thickness and wafer-scale uniformity. Two of the critical issues in unlocking the potential of graphene are the ability to deposit ultra-thin high-K dielectrics on grapene and fabricate low resistance contacts to graphene. Technologically, it is desirable to use atomic layer deposition (ALD) for this purpose. The inert nature of graphene however has made ALD on graphene very challenging. This presentation will give an overview of ALD techniques that were developed in our lab to initiate oxide and metal ALD on graphene to form ultrathin dielectrics and low-resistance contacts, without deteriorating graphene’s electrical properties. In addition, ALD might prove as a key enabler for tackling the current challenge of large-area growth of 2-D materials with wafer level uniformity and digital thickness controllability. We have implemented plasma-enhanced ALD to synthesize large-area MoS2 thin films with tuneable morphologies i.e. in-plane and vertically standing nano-scale architectures on CMOS compatible SiO2/Si substrates. The large scale 2D in-plane morphology has potential applications in nanoelectronics, while the 3D nanofin structures could be ideal for catalysis applications such as water splitting.

Abstract
New devices based power converters and systems Keywords—Wide band Gap semiconductor used in rectifier with focus on GAN transisitor When dealing with power conversion in a data center, the efficiency and cost-effectiveness is key! Due to the size and capacity of a modern data center, even small efficiency improvements in the power conversion from the incoming AC to the server load have great impact in terms of cost saving. Over time, Eltek has been exploring wide band gap technology, using GaN transistors instead SiMoS Fets in order to achieve higher efficiency and reliability. Together with Infineon, Eltek have for more than 2 years participated in an EU research program which now has resulted in a new 3kW/48Vdc rectifier with a peak efficiency of 97,8%. The combination of Eltek’s proven High Efficiency (HE) technology and Infineon’s GaN transistors has enabled a truly cost effective rectifier in the Super High Efficiency range. With modern silicon devices it is feasible to raise efficiency in the 230Vac-48Vdc conversion step to 98%, but based on the experience from our extensive research we are convinced that this efficiency can better be achieved by utilizing the GaN technology; simpler, more reliable and more cost effective. In our Super High Efficiency rectifier, we have been using totem pole topology with a lot of different technical issue. The PFC has a peak efficiency of approx. 99% and the rectifier has peak efficiency of 97.8% Totem pole PFC This paper will describe how and why GaN is the key to achieve reliable 98%+ efficiency.

Abstract
By 2030, 50% of the car costs are expected to be SC components related. While it is an exciting source of growth for the complete supply chain, the car industry sets a great challenge for all of us: reaching the ppb level in failure rate at the component level. Material purity and contamination control could play key enabler roles. However it requires a new collaborative approach to validate expectations and identify the most adequate investments to meet the “zero defects” goal. From the list of potential material options, there is an increased value to tackle the non-visible particles that are sources of latent defects. Actually, the defectivity monitoring challenges in terms of limit of detection create a “Black Box”. The industry is here in the 3rd generation of contamination control strategy where base line and excursion control could be improved with an adequate contamination management strategy. A collaborative engagement model exists where device makers and experts in purity work together in task force mode. This is the “New Collaborative Approach”.

Collective Die Bonding Technologies for Heterogeneous Integration in Advanced Packaging

Uhrmann, Thomas

Abstract
As die area is constantly reduced especially for small package sizes and heterogeneous integration with high interconnect density becomes crucial. For large packages sizes heterogeneous integration and die segmentation gets an increasing role of processing applications. Here, heterogeneous integration leads to an overall increased yield, mainly as smaller dies generally can be produced with higher yield. In the same time and most importantly, memory, processors, sensors and such from different sources can be combined using heterogeneous integration. Aforementioned yield improvements by splitting dies into several parts and improving the performance cost. Combining the segmented dies in an advanced package can be done by two different bonding technologies, namely sequential die bonding or a collective die bonding approach. For the collective bonding, individual dies are populated and tacked either on an interposer or a so-called handling carrier, depending on the bonding technology applied. In case of tacking die face-down on an interposer or other active silicon die, bonding is usually being done by thermal bonding. Here, heating and cooling of the substrates are only done once, considerably reducing process cost and thermal budget of the underlying substrate. The second case is tacking the dies face up on a carrier substrate. This reconstructed dies on a carrier can now be processes again on wafer scale, this means preprocessing steps such as direct bonding can be done before bonding the wafers using fusion or hybrid bonding. In this presentation we will show different integration approaches for collective die bonding for both thermal bonding as well as fusion / hybrid bonding. For both processes, results in terms of die placement and sequential alignment accuracy of the integrated process will be compared and discussed, together with current and potential applications of these processes for future devices.

Abstract
Flexible electronics will play a pivotal role for enabling flexible displays and sensors that will break form factor constraints and unlock new product use cases. The transistor is the fundamental building block for electronic devices, so a flexible transistor is the first step to turning this vision into a reality. Organic-based transistors (OTFT) have always been seen as the most flexible transistor option, and this talk will explain how the performance of OTFT has now exceeded amorphous silicon ensuring that product designers no longer need to compromise performance to achieve flexibility. For example, in terms of mobility, manufacturable OTFTs are now at least three times better than amorphous silicon, whilst having leakage currents nearly 1000X lower – both of which bring direct performance benefits to the device electro-optical performance alongside the benefits of flexibility. In particular, OTFT technology opens a new avenue for flexible displays and sensors on commodity plastics – it enables glass-free, thin, light and conformable devices, combined with a low manufacturing cost that is driven directly by the uniquely low temperature process (sub 100ᵒC) afforded by OTFT. The process has been designed so it can be easily transferred into existing display factories providing a quick route to high production capacity and yields. FlexEnable is now working across the supply chain to establish the infrastructure necessary to bring the next generation of products to the market.

Sensors and electronics need the functionality of micro-controller ICs for data collection, data processing, digitization and data transfer to a host system. Therefore, any flexible electronic system will require a technical solution for embedding and interconnection of ultra-thin microprocessors in a bendable film based package. The presentation will first explain the technological requirements for integration of thin IC on or in flexible film substrates. Key elements here are the manufacture of robust thin semiconductor devices, the preparation of very fine line metal patterns and adequate chip bonding and interconnection techniques. Latter topics can be realized in two different ways for chip orientation: face-down (flip chip) or face-up die bonding. In the second case, interconnects must be aligned with respect to I/0 contact pads of ICs. As the distance between two contact pads may be in the range of just 20 µm to 40 µm the resulting alignment accuracy of dies with respect to the interconnect lines has to be less than 5 µm. When using flexible film substrates as integration platform and roll-to-roll (R2R) equipment for manufacture this requirement represents a challenging task due to possible shrinkage or expansion of the film roll. Thin chip foil packages with embedded microcontroller ICs were demonstrated successfully by Fraunhofer EMFT using single sheet film substrates. In order to achieve the next major step towards R2R manufacture we are currently setting-up a laser direct imaging (LDI) system for R2R lithographic patterning of interconnects and wiring schemes. Key advantage of such laser imaging system is its capability to correct the UV exposure process locally and, if necessary, individually at any chip position. Such “adaptive lithographic patterning” is supposed to bridge the gap between alignment requirements and geometric distortions in the web substrate. First results will be shown at the conference for the first time.

New device technologies and applications with their ever increasing performance and functionality are driving the requirements and innovation for assembly and packaging. The technology boundaries between semiconductor technology, packaging and system design are becoming blurred. As a result chip, package and system designers will have to work closer together than ever before in order to drive the performance for future microelectronic systems. In addition heterogeneous integration will be an integral aspect for all future advanced electronic applications.

Predictive Probing: A novel approach to minimize efforts at final test

Abstract
Quality control plays a crucial role in the manufacturing of premium products. Measures for quality control are implemented, on the one hand, right after crucial process steps to ensure single process quality. On the other hand, the application of sophisticated test procedures during final test guarantees high quality of the final product. For instance, in LED manufacturing, high effort is spent to probe every single LED chip: in dedicated probing equipment, ultra-thin needles are used to contact an LED and measure its brightness, color and electrical properties. With thousands of LED chips to be tested per wafer, this is a time-consuming and expensive step. Predictive probing aims at significantly reducing the probing time and effort in final test and follows two objectives: (1) Identify a limited set of chips that have to be tested. (2) Reconstruct the parameters also from those chips that were not probed; this includes the detection of defect chips. To achieve these objectives, up-stream metrology data is utilized. A set of machine learning algorithms (including a neural network) takes these data to identify critical chips and to predict probing results. This concept was developed and demonstrated in a 3-years R&D project together with an LED manufacturer. As a result it is possible now, to omit the measurement of 93% LED chips on a wafer, which leads to a drastic decrease in overall measurement time and cost, and still predict the brightness, color and electrical parameters of all LEDs – with an accuracy that fulfils the specification of the manufacturing partner. The principles of the approach and the knowhow gained during the development can be transferred and applied to other applications and industries, where predictive probing can significantly lower cost and efforts in quality control.

Abstract
Wide band gap (WBG) semiconductors (SiC, Ga2O3, GaN, AlN, diamond) have certain outstanding physical properties which make these materials so attractive for power electronic, optoelectronic and rf applications. However, the growth of bulk crystals with large diameters and with high quality and yield and the manufacturing of substrates from these crystals are much more complicated in comparsion to the very mature materials Si and GaAs. In the presentation the difficulties in growing bulk and epitaxial WBG semiconductors will be introduced and technical solutions will be shown which have been developed to overcome the existing obstacles. Special focus is put on SiC, GaN and AlN. The status of these materials is compared in terms of avaible crystal size, totally produced wafer area and typical crystal defects. An outlook will be given to the next scientific and technological steps which must be solved in order to accelerate the commercialization of the materials further.

Abstract
The upcoming Internet of Everything (IoE) devices demand miniaturized rechargeable batteries, who distinguish themselves through a high level of safety as well as increased energy and power density per footprint area. Thin-film all-solid-state lithium-ion batteries deposited on highly structured silicon substrates are ideal candidates to match these requirements. The technical transition to solid-state electrolytes means significant improvement of battery safety. Three-dimensional (3D) battery concepts, including deposition on structured surfaces with high aspect ratio, have been shown to improve both capacity and rate performance of all-solid-state batteries. At Fraunhofer IPMS-CNT we are driving the development of functional layer stacks by atomic layer deposition (ALD) allowing direct integration into microsystems. ALD enables conformal, pinhole-free deposition of nanometer thin films and composition control on an atomic level. However, deposition of lithium-containing materials by ALD is a challenging task. In order to make the entire 3D battery by ALD, single layers, interfaces, and the whole layer stack have to be tailored. For semiconductor compatible design and production we manufacture on 8 inch silicon wafers using standard industrial thin-film deposition equipment. For battery integration into silicon technology lithium-ion diffusion into the silicon substrate must be inhibited. Undesired lithium-ion outdiffusion would result in poor cycling stability and failure of neighboring devices. In order to enable deposition on nanostructured silicon substrates, there is demand for as thin as possible non-active battery layers. In this work, lithium-containing functional layers and ultrathin lithium- ion diffusion barriers for on-chip 3D batteries were investigated.

Abstract
Main bottleneck to the realization of next generation computing systems for all big-, secure-data applications and related industries, including System-in-Package and System-on-Chip based solutions, is the lack of off-chip (off-core) interconnects with low latency, low power, high bandwidth, and high density. The solution to overcome these challenges is the use of photonics. Photonics as an underlying technology is addressing the following main technological challenges of the next generation computing systems such as i) Off-chip interconnects, ii) Massive switching matrix, iii) Disruptive system architectures, iv) Cooling concepts, v) New peripheral component interconnect express, vi) Memory fabric, vii) Novel computing functions in order to enable Quantum- & Neuromorphic Computing, AI. Next Generation Photonics Platform will enable the disruptive computing technology and photonics enabled architectures, leading to faster, cheaper, power efficient, secure, denser solutions for applications and industries. Further, generic co-integration with all building-blocks of computing technology will be possible, since photonic based standard interfaces between building blocks are introduced and implemented.

Abstract
Semiconductors remain a fast growing market worldwide. Since 30 years, there has been revenue increases by ~ 10% yoy. Looking at the segments, memory/logic remain strong, while sensors and opto-electronics are growing. Technology scaling towards smaller structures and larger wafers is driving up costs and investments, and many semiconductor manufacturers cannot afford to pursue the smaller scale. In memory, consolidation of manufacturers who drive DRAM and Flash developments is done. Also, regionally China and America are growing, Japan and Europe are losing share. The focus of this paper is the impact materials play in this changing business. Interestingly, no technology or wafer size has disappeared from the manufacturing landscape in the last 20 years. Due to product longevity and the addition of new features and functionalities to those existing bases, high voltage, non-volatile memories, RF, Si photonics, to name a few, the products meet the demand but it is clear that these new emerging applications will drive specific demands on material development. Another perspective is that increased quality in yield and reliability drives material suppliers to provide enhancements in defectivity and quality controls. A minor quality loss can lead to massive wafer supply risk if reliability or yield is impacted. And Europe’s semiconductor industry faces a competitive disadvantage over other regions of the world. Europe’s EHS compliance and chemical legislation (EU REACH, RoHS) regulate materials differently to other manufacturing geographies. In some cases, this EU regulatory landscape drives the development of alternative materials. As China brings the mega-fabs online with the advantages they have (funding, regulations, captive customers), we will be forced to make the solutions cost effective. The demand for new materials, the requirements for superior qualify and necessity of solutions for EHS pressures will drive inventive solutions at the forefront of this business.

Abstract
The next network generation will enable high bandwidth applications like Ultra HD videos for mobile devices and at the same time support wireless Virtual Reality (VR) gears. Smart city and smart home applications are requiring a high flexibility in integration of different devices into the network. IoT and wearables are less demanding in terms of data rate, but mean a tremendous increase of connected devices and at the same time a strong demand for super low power. Beside these applications, advanced health care, connected cars and autonomous driving are emerging. These mission (?) critical applications are requiring a high data rate together with the absolute reliability of the systems. GLOBALFOUNDRIES’ new 22FDX-mmw technology is targeted to serve ultra low power, digital data processing and analog IP integration and allows system architects to design IP into one single SoCs. To package these mixed signal SoCs, our industry is facing complex challenges by a high number of digital I/Os, sophisticated power and ground networks and highly sensitive RF signal routing. The packaging integration of millimeter Wave, in combination with high frequency antennas needs new levels of chip-package-co-design and thorough usage of advanced packaging materials. In this presentation, we will show the challenges associated with mmWave based mobile networks, packaging solutions that can be adopted and how the design flow can improve system integration and overall performance.

Abstract
During the last two decades of emerging memory R&D a slow but distinct paradigm shift from stand-alone to embedded application targets is observable. For nearly all new memory concepts, independent of their time of introduction and pace of maturing, the first ambitious goals to replace highly specialized standalone memories, such as commodity DRAM or NAND-FLASH, were quickly shattered. The inability of emerging memories to intercept high density stand-alone memories is mainly caused by a slower scaling insufficiently compensated by the "value add" they provide in this particular application space. In the embedded memory world bench-marking the competitiveness of a memory solution is markedly different. Here the application focus is mainly on code-storage and the boundary conditions for the cost per bit are not solely driven by scaling, but are set by the CMOS-platform and the integration complexity required to add a memory solution. Key advantages of emerging memory concepts, such as low power and ultra-fast write when compared to FLASH as well as their non-volatility when compared to DRAM, are now weighted differently. As a consequence, CMOS-foundries are ringing in the final round for emerging NVMs to compete for a place amongst the main-stream memory solutions. In this talk the status of embedded memories utilizing ferroelectric and ferromagnetic domain reconfiguration will be reviewed. Namely the two long term NVM contender magnetic random access memory and ferroelectric field effect transistor. In recent years both concepts overcame their scaling limitations by major breakthroughs in material development and device design. The revival of ferroelectric memory devices was led by the discovery of CMOS-compatible and scalable ferroelectric hafnium oxide. In the case of magnetic memory devices the introduction of spin transfer torque as well as material and interface engineering to provoke perpendicular magnetization paved the way for a new generation of devices.

Abstract
Commercially available flexible printed circuit boards are manufactured by using adhesives for bonding thick copper foil on polyimide in a lamination process. For realization of thin foil systems without adhesives we present a highly customizable, additive process using polyimide foils, PVD technology and a maskless direct imaging process to manufacture flexible polyimide based circuit carriers in short time and small lot sizes. First, polyimide foil is used as substrate for sputtering a thin Cr/Cu metal layer. Then photoresist is applied on the metalized foil by conformal coating. Structuring of the resist is carried out by direct imaging and subsequent developing of the resist. After applying of copper electroplating for enhancing the opened tracks, the mask is stripped off and the metal layer is etched until the base PVD metallization is completely removed. Finally a suitable metal finish for assembly processes is applied on the copper tracks by electroless plating of nickel and gold. With these base substrates a thermal direction sensitive mass flow sensor element was realized using low-cost passive SMD components such as a resistor as a heater and NTCs as temperature sensors on both sides of the resistor. The development of the read-out circuit as well as the characterization of the low cost flow sensors are in progress. The presented process chain combines the advantage of maskless lithography with its short preparation time on one side and batch processing for an industrial approach on the other side. The process offers thin, flexible and individualized sensor elements with easily scalable size and configurable layout without additional adhesives.

Abstract
As electronics industry enters a new era of IoT devices, more and more sensing modules are becoming essential to make devices “smart” and "intelligent". Representative ones are camera modules, proximity and ambient light sensors, biometric (3D ID) sensors and MEMS devices. As signal sensing and processing become more advanced and demanding, the adhesives used need to meet more stringent requirements of process flexibility, application accuracy, adhesion strength, drop test and reliability. Henkel evolves together with leading sensing module makers by further developing specialized adhesives for them. For example, in camera modules, low temperature cure and low shrinkage are critical for active alignment and enabling ultra-high image quality. Hybrid resin and curative designs enable cure below 80°C while achieving ultra-low cure shrinkage and excellent adhesion to various substrates. A versatile chemistry toolbox - incl. epoxy, acrylate, silicone and hybrid resins - is used to develop new adhesives for MEMS with a wide modulus range (1 MPa up), stable modulus during operation and high toughness. Through catalyst selection, different UV and/or thermal cure mechanisms are entailed to enable different application processes with higher output. For each chemistry, the adhesive rheology must be tailored to fit challenging aspect ratios using needle dispensing, jetting, printing or laser assisted transfer. For image sensor, lid, cap and stiffener attach and grounding, various levels of electrical and/or thermal conductivity are incorporated by specially developed resin and filler systems. Finally, adhesive FILM is getting preferred over liquids due to advantages in bond line thickness control, tight keep-out zone, low warpage and low stress by low temperature cure, latent catalyst selection and B-stage processing. This presentation will give a clear overview of the sensor assembly challenges AND innovative adhesive solutions to enable Next Gen Sensing Module developments.

Abstract
Electronics market trends continue to drive innovation for higher functionality with smaller form factors and reduced power consumption. To meet these demands, the design of semiconductor devices is changing more and more from traditional wire bonded packaging to so called “advanced semiconductor packaging“ based on Wafer Level, Flip Chip and 2.5D/3D Stacking technologies. Fan-In and Fan-Out Wafer Level Packaging (WLP) and Through Silicon Vias (TSV) for instance are successfully replacing proven wire bond technology today. This has a significant impact on the typical assembly materials being typically used in the Back End Of Line (BEOL) production of semiconductors. For instance, there’s often no need for die attach adhesives and traditional transfer mold compounds anymore being currently widely used in SO, QFN, QFP and BGA type of lead frame and laminate devices. This presentation will give a high level overview of the relative new and different assembly materials being developed, qualified and used in “advanced semiconductor packaging“ as such. This includes very thin “Wafer Applied Underfill Films” for 3D Stacking of thin TSV Wafers, specialized “low stress and low warpage” adhesives/underfills for Flip Chip and Interposers and low shrinkage and ultra-low warpage wafer encapsulants for Fan-In and Fan-Out devices. As the proven wire bond technology will certainly continue to be used in high reliability and automotive semiconductors and sensors, also new adhesives with higher thermal conductivity, lower temperature cure, ultra-low modulus and pre-applied “B-stage” capability will pass by ….

Abstract
Following a current consumer trend, the demand for high-performance and highly-integrated multifunctional flexible systems has significantly increased in recent years. This has generated the need to develop hybrid systems in which printed circuitry is combined with silicon-based integrated circuits or surface mounted device (SMD) components. Flip-chip (FC) assembly of (opto)electronic components is a key technology in system packaging and integration because of the advantages it offers over the most commonly used wire bonding technique. With decreasing chip size, the density of interconnects increases, which demands advanced high-resolution interconnection technologies. Furthermore, with large-area flexible electronics on low cost polymer foils gaining significant attention lately, the compatibility of the interconnection technology with the carrier substrate has become more significant than ever. At Holst Centre, we have developed two complementary technologies that enable fast and high-resolution integration of FC assembly components onto flexible foils using light. The interconnect material (lead-free solder pastes as well as electrically conductive adhesives) is deposited onto flexible printed circuitries at unprecedented high speed using a laser-assisted digital deposition technology. In this talk, we will present the deposition of an array of 10 000 dots of conductive adhesive (< 100 µm in diameter) within less than a second. The interconnect process is then completed by soldering the components to the substrate using a novel roll-to-roll compatible soldering technology (photonic soldering), which exploits intense pulsed light generated by conventional flash lamps. In contrast to convection reflow soldering (the industry standard technology), photonic soldering is fully compatible with the integration of components on low-cost flexible substrates such as PET, while reducing the soldering processing time down to few seconds.

Abstract
3D heterogeneous integration opens new paths for System On Chip (SOC) and System In Package (SIP) to integrate computing, storage, in and output and other functions in a system efficiently. As interconnect requirements between the various components differ in terms of bandwidth and energy per bit, 3D technologies need to provide different interconnect solutions within a system. In order to realize significant wire length savings of a partitioned processor, small interconnect pitches below 1µm are required. Connections to off-processor memory are longer and have wider pitches. In this presentation, the co-existence of these different 3D interconnect technologies and their need for new materials and integration solutions is discussed.

Mongillo, Massimo

Abstract
In this talk I will present the recent progress made by IMEC in the fabrication and integration of basic quantum circuits targeting qubits into a 300mm FAB. Quantum Computing holds promise for solving complex computational problems which are intractable by classical calculators. The basic ingredient for the implementation of a quantum computer is the availability of a two-level system mimicking the classical bit “0” and “1”(the qubit), on which we can encode the basic information. The exceptional computation power of a Quantum Computer originates by the quantum-mechanical property of superposition, according to which the qubit state is defined as an arbitrary linear combination of the two constituent bit states. At the qubit level, two main solid-state implementations are currently explored at IMEC. They are based on individual spins in Silicon and Superconducting circuits. Spins in silicon have demonstrated the longest coherence time in any solid-state device as a result of the lack of hyperfine interaction coupling the spins of the nuclei and the electronic spins. Another approach makes use of Superconducting devices, which, to date, represent the most advanced solid-state implementation of a qubit. Although this technology has proven to be mature for the implementation of basic Quantum Algorithms, it presents unique challenges in term of integration of a large (millions) array of qubits, necessary for error-correction. Given the rather large foot-print of an elemental Superconducting qubit, this platform need to demonstrate its viability in terms of up-scalability. In the long term, both qubits platform need to be integrated into a larger system comprising the control electronics routing the necessary signals to the physical qubit layer. In IMEC we are pursuing these research lines leveraging the extended know-how in terms of large-scale integration and system architecture.

Abstract
Today, GaN-on-Si is accepted as a break-through power electronics technology. The favorable materials characteristics and the e-mode lateral HEMT device architecture have led to disruptive device performance. Issues with trapping effects and reliability that plagued early versions of the technology have been addressed and first products are in the market. Today imec is focused in further increasing the performance and reliability of its 200mm/8-inch GaN-on-Si e-mode devices for 200V and 650V applications. Next to improving GaN-on-Si e-mode technology, imec is also investigating the next generations of GaN technologies that will provide: higher level of integration (GaN-IC), higher performance and larger voltage rating Particularly attention is dedicated to GaN-IC that allows to unlock the full potential of the fast switching GaN-based power devices. Indeed, monolithic integration of a half-bridge, co-integration of the GaN drivers, and free-wheeling diodes offer a way to reduce parasitic inductances, while on-chip temperature sensors and protection circuits increase the robustness. Such power GaN-IC’s pave the way for unprecedented compact high-end power systems. In this talk, imec will review the status of GaN-on-Si e-mode device technology as well as its recent progress on technologies for GaN-IC.

El Kazzi, Salim

Abstract
During his memorizing lecture “There's Plenty of Room at the Bottom” in 1959, Richard Feynman predicted that surface tension and Van der Walls Forces will be crucially important in the future nanoscale applications. After nearly 60 years, the discovery of Graphene and its related 2D materials are surprisingly confirming these predictions. The use of this family of materials is opening a new era of research innovation in different fields. The imagination of researchers has allowed them to use 2D materials for water treatment, clean energy, (bio)sensing and interesting optical applications. 2D materials are also expected to help in the expected convergence of 5G communications with the Internet of Things (IoT) where faster and connected computers can be achieved by reducing the size of their circuits. All this fantastic work is however stopped at the proof of concept levels. If these materials would ever see mass production and foundries would accept to have them in their machines, technological solutions to integrate 2D on large area surfaces are fundamental requirements. In this talk, we will share on our journey to bring these 2D materials from the lab to the fab. The discussion will be first focused on the growth and transfer of 2D materials and how we are trying to understand and solve the main challenges of these Van der Walls materials. An emphasis will be given to the role of surface tension and interface engineering in the making of the 2D-based devices. In a final part, the talk will cover our strategy to integrate 2D materials in a fab production environment while using the learnings from the lab. This work is expected to offer insights on both the main challenges and solutions of MX2 integration for future CMOS technology

Abstract
ITN Energy Systems and ENrG Inc. have developed and demonstrated a promising new thin, flexible solid state lithium rechargeable battery (SSLB) for flexible electronics, smart wearables, and medical devices. Combining ITN’s SSLB technology with ENrG’s ultra-thin flexible ceramic solves the capacity and packaging issues that have thus far limited the thin film battery technology to limited niche markets. With a capacity greater than 20 mAh in a thickness less than 250 microns, including hermetic packaging, the new SSLB enables energy density greater than 1,000 Wh/l while maintaining the long recognized benefits of enhanced safety and durability provided by the all solid state chemistry. Results are also presented for a new Flexible Integrated Power Pack (FIPP) that add in-field solar recharging by combing the SSLB with Lucintech’s high efficiency CdTe solar cells. The new SSLB and FIPP products support operation across a wide range of duty cycles including high current pulses required for many wireless, display, and medical device applications.

Abstract
Abstract— Due to large topographic gaps between the chips and mold substrate, the next generation of high density FO-WLP will require fine RDL plating resists that can achieve as low as 2um line/spaces(L/S) with a wider common depth of focus (DOF) margin. In order to meet these requirements, we developed a novel chemically amplified positive tone resist. In this study, we focused on photo acid generators (PAGs) which are one of the major components of chemically amplified resists. We found that controlling the acidity of the generated acid from PAGs after exposure was a key approach to get good profiles on Cu sputtered substrates and wider DOF margins. Keywords—Plating resist, FO-WLP, fine RDL, photo acid generators.

Abstract
Mühlbauer introduces a complete solution for the Reel-to-Reel production of multicomponent products on flexible substrate in the area of LED, active RFID, sensor labels etc. The solution consists of systems that are capable of high-volume manufacturing processes. The upstream production process comprises the production of a flexible circuit, whereas the subsequent process attaches different components to the substrate which is the electronic portion of the final product. The flexible substrate production technology is a completely new development. Starting with the attachment of LEDs, the process was continuously extended to a multicomponent process. Further progress was achieved in the component attach and curing technologies according to different end applications and the substrate material selection between aluminum and copper for flexible substrate production in relation to their respective areas of use. For example, with Mühlbauer’s Reel-to-Reel RFID Antenna Production machine ACS 20000, the low cost materials PET and aluminum can easily be transformed into aluminum antennas on PET. After the launch of the flexible LED production line TAL 15000_LED in 2015, Mühlbauer further developed the assembly process towards a universal system: the Multicomponent Line. Besides the standard jetting of adhesives, the dispensing of ICPs and solder paste is now also possible. As a result, new curing requirements like the integration of an inline reflow oven, were developed. Furthermore, the component attachment has been simplified and enlarged so that now, a high variety of components can be attached: SMD, sensors, capacitors or even Flip Chips and other electrical components, which meet any future trend in flexible electronics.

Printing high aspect ratio narrow silver lines using nanoparticles

Zhang, Zhiyi

Abstract
In printable electronic device, narrow metal lines with low electrical resistance are essential. Commercial gravure, flexography or inkjet systems on the market can produce 30-100 µm wide lines by properly choosing the ink and substrate, this feature size is still about one order of magnitude larger than what is required in many electronic device applications. Other R&D printing technologies like high throughput gravure, reverse-offset printing, and electrohydrodynamic jet printing can achieve a linewidth of 1-5 µm at the expense of line thickness, which is normally characterized by a very low thickness-to-width aspect ratio, often far less than 0.05. Currently, it is very challenging to print narrow metal lines with high thickness-to-width aspect ratio and thus low resistance. In this work, we report a method of obtaining 4.6 µm wide printed silver lines with an elliptical cross-section and an aspect ratio of 0.7. The silver lines were obtained by jetting a silver nanoparticle-based ink onto an SU-8-coated PET substrate to form well-defined silver lines, and then heating the lines to transform them into high aspect ratio narrow lines through ink dewetting and receding. The simultaneous dissolution and redistribution of SU-8 by the ink results in a concave structure, which prevents the lines from bulging and allows the lines to sink into the SU-8 film. The sheet resistance of the obtained 4.6 µm lines was measured to be 0.05 ohm/□, and using special pattern designs, the method can also be used to get 0.5 µm wide silver lines, with an aspect ratio of 1.0. The obtained wires are suitable for printing high-performance electrical devices.

Abstract
Increasingly WLCSP are used as solution for packaging, especially when the area needed for I/O matches the area needed for the function. Industry trend is to go thinner devices and smaller pitches. The mechanical integrity of WLCSP’s is stressed not only in the application, but also during board assembly at the customer. The breakthrough technology presented provides protection for both the top and bottom of the product, thus protecting the 8 corners of the device during handling at manufacturing and customer. Different material sets and molding technologies for encapsulation of the WLCSP were investigated, each with their own merits. The challenges experienced to create the two side encapsulated concept and way forward to overcome them will be shared. First results on Board Level Reliability will be shared. The encapsulation concept to achieve full encapsulation is demonstrated at supplier site and the building blocks towards a true industrial solution is shared. Balancing the front and back side thickness of the compound enables reduction of the overall height while at the same time improve the BLR performance compared to more well-known 5 side protected WLCSP in the same package thickness.

Abstract
The Automotive Industry is seeing more dramatic changes in the next few years than in previous decades combined. Vehicles are becoming always connected and part of the internet. Drive trains evolve from combustion engines to mixtures of hybrid and electric vehicles with new challenges (e.g. for reach). Most dramatic is the change to more and more assisted driving up to future level 3-5 automated vehicles. All of those factors result in the development, that existing E/E architectures are not capable of supporting those requirements. Instead of small evolutionary changes some more dramatic departure is required. While the new functions demand new solutions, many of the existing functions in a vehicle (e.g. body comfort functions, …) do not require new features and therefore a new architecture, that allows the reuse of many legacy ECUs without changes can have a huge economic benefit. The presentation will show how concepts from IT and Network Infrastructure Solutions can be brought into Automotive while taking automotive specific requirements (e.g. startup times, thermal management) into consideration. The presentation will touch on several of the attributes and consequences, e.g. of different functions into one box (Virtualization, Isolation, Validation) and Communication schemes for such an architecture. Additionally we need to consider, that cars are an attractive Target for Hackers. In highly networked cars we need to be concerned about protecting privacy, increasing safety and preventing unauthorized access. Connected vehicles create a multi dimensional challenge to address vehicle safety (Zero accidents by human error), security (Zero accidents by system hacks), functional safety and also device reliability. Another topic is, that such a new architecture requires rethinking of conventional wisdom for functional safety.

Comparison of different SOI substrates from process integration and manufacturing complexity point of view. Benefits of SOI and C-SOI based approach for flatness and dimensional precision of the released structures. • Combination of C-SOI based MEMS and wafer level packaging by patterned capping wafers with poly Si TSVs. Properties of advanced C-SOI and TSV substrates. • C-SOI based approach for high performance inertial sensors, with benefits in process integration, reliability and performance optimization. • Thick SOI based optical waveguides using E-SOI substrates for maximum efficiency. Okmetic’s new turnkey solution of providing full C-SOI process flow, from silicon crystal growth to cavity patterning and SOI wafer manufacturing, from one source is introduced. Fully in-house C-SOI processing allows an industrial-scale solution to C-SOI manufacturing, and enables the sensor manufacturers to focus on their core competencies in the directly sensing-related parts of the manufacturing process. Integrating the reliability-critical fusion bonding part of the MEMS process as a part of starting wafer manufacturing enables also streamlining of the manufacturing process flow, simplified process integration, and improved long- term reliability of the MEMS devices. In-house crystal growth and substrate wafer manufacturing enable full customization of material properties, such as Si layer resistivity and orientation, of each layer of the C-SOI structure.

Paglia, Massimo

Abstract
A typical On Board battery Charger application for electric vehicles consists of a power factor correction stage (PFC) and a DCDC converter stage, both require the highest efficiency possible in order to deliver as much power as possible to the battery pack. Focus of this work is the 3 phase 10 kW PFC based on Silicon Carbide Mosfet which regulates the output voltage to 700V starting from a nominal input voltage of 230Vrms at 50Hz. Three parameters measure the performances of the system: total harmonic distortion, power factor and efficiency. Ideally they should be zero, one and 100% respectively. The configuration selected is typically known as inverter, made by 3 half bridges with each central point connected to a dedicated boost inductor, and each high side drain and low side source connected to the bus capacitor. 1200V SiC MOS 80m devices were used together with the recently released ON Semiconductor dedicated SiC gate driver, NCV51705. A digital control has been adopted by means of a mid-range microcontroller. The implemented strategy is based on a field oriented control approach where the rotating DQ domain has been selected aligning the D axes with the input voltage space vector. The selected HW together with the digital implementation represents a bidirectional system, therefore power can flow either ways by modification of the D axis reference current sign. The control strategy works on an interrupt running at 20 kHz using one ADC, 12 bits 1Mbs and one sample and hold. PWM frequency set to 70kHz. Experimental results demonstrate that the PFC was able to achieve as high as 98.7% at 6.6kW with a consistent efficiency above 98% at higher power output. THD was well below 5% from 3kW onwards and PF is above 0.99 from 4kW. All evaluated at nominal input voltage, 230Vrms.

Knoops, Harm

Abstract
Atomic scale processes such as atomic layer deposition (ALD) and atomic layer etching (ALE) are increasing in popularity with more and more applications requiring or benefitting from atomic level control. ALD and ALE provide the control they do because they are based on self-limiting surface processes. This contribution will discuss the basics for both techniques and discuss how they can be further advanced. For ALD two trends will be discussed: i) controlling the ion energy in plasma ALD to tune material properties. Generally processes are optimized to have minimal ion energies to avoid potential damage. Interestingly, for these low damage plasma sources, the ion energy can be increased by substrate biasing providing additional knobs for tuning film properties. Key examples are stress-control of oxides such as achieving near-zero stress in TiO2 and reduction of the resistivity of conductive nitrides (e.g. for TiN, HfNx, and NbN). ii) Usage of novel plasma gases. For instance H2S plasma gas mixtures have been shown to allow growth of 2D-MoS2 at low temperatures and SF6 plasma was found to allow ALD of AlF3, which could be of interest as an optical coating or for batteries. For ALE the basics will be discussed and how these can be used for applications. More and more processes are being developed (e.g. ALE of GaN, AlGaN, Si, SiO2 & 2D materials). Interestingly besides the exact control of etch depth, other aspects of ALE might turn out to be more important for certain applications. For instance ALE of AlGaN was found to reduce the surface roughness, while generally plasma etching would increase the surface roughness somewhat. Other advances for both ALD and ALE are expected to be in the form of combinations with other techniques. Therefore clustering of ALD and ALE tools with 2D materials growth can allow precise control of interfaces and allow avenues into selective growth, surface cleaning and etching.

Abstract
Gradually electronic devices are finding their way towards the human body. Body patches are being designed that provide continuous monitoring. Intelligent catheters assist during minimal invasive surgery, and tiny implants stimulate nerves with the aim to replace traditional medicines. Despite their apparent potential progress is however slow, certainly compared to the non-medical electronic industry. One of the reasons is the lack of scalable open technology platforms. In this presentation a selection of promising emerging in- and on-body electronic will be reviewed. Large European consortia supported by ECSEL and PENTA, are developing and implementing not only the essential open technology platforms, but also the necessary manufacturing infrastructure. The recently established Health.E lighthouse will further promote the open technology platform concept for medical devices to realize the “Moore for Medical” vision.

Abstract
While metrology tools are getting more advanced and providing plenty of valuable data of process and product, there is still a lack in evaluating and combining these information for an integral process analysis and real-time control. In plasma processing optical emission spectroscopy is well known and often established as a process monitor by observing a single emission line e.g. to detect an endpoint or to survey the process stability. However, using the spectroscopic plasma monitoring technique all acquired spectroscopic data is evaluated simultaneously and in real-time and thus, provides a more comprehensive insight in the plasma chemistry, the composition of the plasma and its temporal evolution. Combing the spectroscopic plasma monitoring data with other real-time plasma metrology data will complete the picture of the plasma process. In order to scope with the more complex and advanced processes for next generation products it is essential to interconnect the metrology tools and its data and data analysis as it is addressed by IoT or Industry 4.0. In an example from solar cell production the benefits of the advanced spectroscopic plasma monitoring technique are illustrated and the advantages of combining metrology tools are outlined.

Abstract
Internet of Things (IoT) is the internetworking of physical devices, vehicles, buildings and other items embedded with electronics, software, sensors, actuators and network connectivity that enables these objects to collect and exchange data. IoT represents the next step towards the digitization of the society and economy, where objects can be interconnected through simply attachable and low power consumption communication networks and report about their surrounding environment. Mobility is a strong domain of industry with potential to employ IoT solutions in huge extent with many possible use cases. Development of IoT systems oriented towards smart mobility is therefore a big and challenging field. Network of IoT systems is based on low power consumption and long lifecycle of the products as the purposes of use can require years of operation in e.g. hermetically sealed casing. In specific cases, an intercommunication of IoT nodes is required. Design, development and production of such systems requires experience and specific skills in different areas, as are the power management, communication, self-test, antennas, casing and others. Among different IoT systems there are many subgroups of mobility sensing elements – static or dynamic, with individual connection to network or mesh connection, oriented towards monitoring of traffic, parking, position of carrier etc. The speech will be devoted to different attitudes to electrical design of static sensors and dynamic sensors based on example of comparison of static parking occupancy sensor for ground integration with at least over 5 years functionality and an hobby unnamed aerial vehicle (UAV) monitoring in 3D and intercommunication of the aerial vehicles.

Abstract
There is an ever-growing interest in sustainable and renewable energy sources such as solar, wind and water power. The rapid development in this field will require new ways of storing and balancing this energy. The power output from solar cells not only varies with the 24-hour rhythm of the sun, but also on shorter timescales with the passage of clouds. The intensity of wind also varies on different timescales, and this leads to large power fluctuations in the grid. To balance the power grid, intermediate energy storage on massive scales is necessary. This energy storage must not only have high enough power density to smoothen the power spikes, but it should also be environmentally friendly and sustainable, just as the renewable energy sources. We have developed a scalable paper-supercapacitor system based on the conductive polymer PEDOT:PSS and cellulose. The cellulose forms a large surface area for the conductive polymer to self-organize onto, as well as a porous network which facilitates high ionic conductivity. We have also shown how the charge storage capacity can be further enhanced by organic forest-based redox-molecules. Furthermore, we have developed new methods of producing the active material, as well as the other device components, in a large area and high throughput manufacturing processes capable of satisfying the future demand for green energy storage.

Abstract
The demand and variety of applications for MEMS sensors has been growing steadily since the first series applications in the automotive sector in the early 1990s. Especially since the rise of fast-moving consumer markets, quick and efficient design has become increasingly important. However, in particular for MEMS, the strong interaction of product design and manufacturing processes is a major challenge. The growing number of applications for sensing of various physical and increasingly chemical parameters, often require specific solutions in MEMS production, chip level packaging and component testing as well. Fast and market-driven product development is only possible through innovative design concepts and the provision of modular process building blocks. A deep understanding of the interrelationships and the development of corresponding simulation tools are further key competencies. As market leader in MEMS sensor business and one of the first MEMS pioneers, BOSCH is continuously pushing forward the development of MEMS technology. The extension of our process platform originally defined for automotive applications to consumer products opens up new possibilities in the realization of complex 3D structures. This enables new product designs that are reflected in high-performance sensors for both automotive and consumer electronics applications. The presentation gives a short overview of the different requirements on MEMS technology compared to standard IC design and manufacturing. It provides insights into the future development in the field of surface micromechanics and highlights challenges and solutions of MEMS technology development and manufacturing as well as design methodology. In addition, we give examples of new design and product concepts and finally question: Does the old MEMS law "one product, one process" continue to apply?

SEMI Standards: Update on Fan-Out Panel Level Packaging Standardization

Amano, James

Abstract
Fan-Out Panel Level Packaging (FO-PLP) technology is an enhanced packaging technology, embedding die in a low-cost substrate which is patterned to allow higher density of IOs than would otherwise be supported by the chip size. A number of different formats – including circular and rectangular – have been proposed for the panels into which the die are embedded, with a large number of different rectangular sizes. This wide range is delaying broad acceptance of FO-PLP technologies, as the tools must be customized for each different format. Panel substrates today range from 300 mm to 920 mm. Cost advantages depend on package and substrate size, and lack of standardization is a barrier to high volume manufacturing. Despite its advantages, fan-out packaging has challenges to overcome. To address these issues, the SEMI Standards Fan-Out Panel Level Packaging Task Force is currently developing standards focusing on panels, targeting dimensions, ID marking and orientation, edge exclusion, and other parameters such as total thickness variation (TTV), bow, and warp. Created in 1973, the SEMI International Standards Program brings together industry experts to exchange ideas and work towards developing globally accepted technical standards. SEMI provides the forum for the essential collaborations that must be achieved to move new and existing markets forward efficiently and profitably.

Abstract
Detecting defects as early as possible is one of the most important needs in semiconductor device production, and there are plenty of methods and tools available to identify defects using visible or ultra-violet light with a variety of dark-field and bright-field techniques during manufacturing. High-throughput electron-beam inspection is also available to catch near-surface defects. However, sub-surface crystalline defects in the active device region, such as dislocations, stress-induced slip-lines, precipitates caused by heavy metal contamination, and similar problems can only be detected after testing, failure analysis and fauilt isolation. We present a novel method, which uses infrared imaging to capture light emitted by the defects themselves in response to an excitation. We show that using this method, certain types of yield-critical defects can be detected and potentially identified early in the front-end process, and corrective actions can be implemented immediately, thus saving valuable time during ramp-up phase. We show that the method is especially suitable for the set-up and control of processes that have a high risk of causing extensive damage in silicon, such as ion implant procedures, or aggressive etch processes.

Abstract
Globalization, Industry 4.0 and increasing price pressure are only a few impact factors influencing the competition in the capital goods industry. There is a trend for machine builders to differentiate by creating individual bundles, consisting of technical products and lifecycle-oriented services, called Product-Service Systems (PSS). Smart sensors are a key enabling technology for availability-oriented PSS. Within the German state-funded R&D project “InnoServPro”, Sensitec GmbH is working with a number of partners to develop innovative service products for individualized, availability-oriented business models. One use case studied concerns the condition monitoring of the primary conveyor belt of a potato harvester. A specially-developed magnetic MEMS sensor, based on the magnetoresistive (MR) effect, is capable of identifying damage to steel rods, which are a major component of the conveyor. This information is used to estimate the remaining useful life of the conveyor, in order to plan maintenance optimally and so increase machine available. These new technologies are already progressing to industrial applications. In tobacco cutting machines the cutters are typically re-sharpened at fixed periods. A new MR-based magnetic sensor is capable of monitoring the sharpness of the cutters to allow local, in-process re-sharpening of the cutters without stopping the machine. This solution provides significant benefits, in terms of increased machine availability due to reduced down-time for re-sharpening the cutters. There are also unexpected additional benefits for the machine builder. The magnetic measuring principle can recognize original OEM-cutters so preventing machine down-time due to use of lower quality, non-original components. New magnetic sensors, based on the MR effect, combined with new software functions for smart signal processing are proving an essential enabling technology for new product-service-systems that benefit both end-users and machine builders.

The scale-up of OTFT backplanes: The long journey from the R&D lab via prototyping lines to the a-Si fab
Brown, Beverley

SmartKem Ltd

Brown, Beverley

Abstract
During the last decade, market demand for higher performance organic thin film transistors has driven the rapid development of higher mobility and improved stability organic semiconductor materials. The short-term expectation is for OTFTs to be introduced into fully depreciated α-Si lines enabling their mass production and use in displays, sensors and printed circuits. From the R&D laboratory, impressive OTFT performance metrics are reported in the scientific literature where mobility values exceeding 5-10cm2/Vs are becoming almost routine. Whilst it is impressive to demonstrate champion OTFT data on small area substrates (10 x 10 cm), the technical challenges of transferring and retaining this performance across to an existing α-Si production line are multitude and varied. During this period, it has also become apparent that the development of a high performance organic semiconductor material should be considered merely as the starting point on the road to industrial scale manufacture of OTFTs. To realise the high performance of the organic semiconductor and the organic transistor backplane requires that materials companies develop a customised stack of interlayer inks specific to their respective semiconductor. In parallel to developing the interlayer materials stack, the compatibility of the materials must be demonstrated for existing processes used in display manufacture including exposure to plasma, to aggressive photoresist strippers and developers to name but a few. The organic materials must deliver performance and processing benefits at acceptable cost which in turn introduces further R&D challenges such as developing an OTFT stack set having a reduced number of mask steps. The discussion set out to describe some of the key scale up challenges including; the impact of a range of factors from semiconductor purity to the effects of plasma sputtering on OTFT performance and proposes a range of industrially relevant technical solutions.

Abstract
The Smart Cut ™ technology applied to the fabrication of SOI, is used in volume manufacturing by SOITEC, serving digital, RF, power and photonics markets. Application of this technology using ion implantation to transfer thin films of compounds semiconductors has also been developed. The Smart Cut ™ process has technical and economical advantages. Transfer of thin layers onto many various materials with both a good thickness homogeneity and a high crystalline quality has been demonstrated. From an economic point of view, the possibility of reusing the remainder of the implanted substrate helps to reduce costs, especially for the III-V materials. We will focus on the application of the Smart Cut ™ technology for two different materials, InP and GaN. InP is widely used for the optoelectronic market. The Smart Cut ™ technology, has been tuned to this material. In addition to the cost advantage of the recycling, different receiver substrates such as GaAs, Sapphire or Si have been evaluated to enable new functions: receiver lift off, lower fragility, better integration. Using the InP-on-GaAs engineered substrate combined with direct wafer bonding, Soitec together with Fraunhofer ISE and CEA Leti have demonstrated wafer bonded 4-junction solar cells with highest conversion efficiency of 46.1 %. We will discuss also how the Smart Cut™ technology can enable the use of InP for RF 5G products. Regarding GaN, Smart Cut ™ technology enables the layer transfer of up to 1 µm thick GaN films either from bulk GaN or GaN on sapphire. We have demonstrated up to 3 cycles of reuse of the GaN donor substrate. Different receiver substrates such as Sapphire, Molybdenum and polycrystalline Aluminum Nitride have been evaluated. Through this innovative engineered GaN substrate, we have demonstrated a 20µm GaN epi growth. This breakthrough could enable new vertical GaN devices for high power application such as electric vehicle powertrain and RF power products serving the 5G market.

Abstract
Numerous systems like automotive, IoT and many more require low latency, data processing efficiency, low power requirements, and meta-data transmission. Machine learning must occur at the sensing node. Edge and very edge computing are essential to maintain the high efficiency of a given system, as well as the mechanism to control the overwhelming data generation and subsequent flows. The sequence of sensing, processing the information, learning, and transmitting/receiving data is the sequence that builds on smart microelectronics and smart engineered substrates. The urgency with which the different applications must innovate imposes a renewal in how the supply chain industry has treated R&D, sampling and solution development. Co-optimization of architecture-technology-engineered substrate made possible the success of RF-SOI for 4G, establishing RF-SOI technology as the incumbent technology. In order to shorten the overall R&D cycle from substrates through systems a co-innovation approach is needed. In a co-innovation strategy the key actors collaborate in early stage at several levels of the value chain to maximize synergy, converge on the substrate-system solutions enabling the fastest time from development through product. This talk will discuss co-innovation, engineered substrate infrastructure and examples of substrate innovations.

Abstract
For years the IC industry has been driven by the demand of Smartphone and tablet. IoT was most expected as the next growth engine but all of sudden, high performance computing (HPC) and AI have emerged as the major driving forces thanks to the booming of crypto-currency mining and both cloud computing and edge computing. There are assembly challenges for HPC and AI, first of all, to achieve high computing performance, the logic IC is bigger and generates high thermal dissipation. And the bigger the die size, the lower the manufacturing yield rate. Secondly, the interconnection between logic IC and the memory needs to be very quick so it won’t slow down overall system performance. Finally, a variety of SiP are required to realize AIoT (AI of Things) To properly address those assembly challenges, a variety of advanced packaging solution are in development. For high power consumption, advanced silicon node is applied for large FCBGA to save the power, and advanced thermal interface material (TIM) with higher thermal conductivity is in development for more thermal dissipation. Furthermore, one big IC can be redesigned as several identical smaller ones with higher manufacturing yield rate, and by utilizing 2.5DIC technology, an interposer with fine lines is introduced for homogeneous integration. As for heterogeneous integration between logic IC and the memory, they are packaged together with 2.5DIC technology or Fan-Out MCM based on fine line requirement for faster interconnection. As for SiP, not only for small form factor, but also better EMI and antenna in SiP are in development for better and faster wireless communication. In this paper, technical risks of each advanced packaging solutions mentioned are reviewed, and possible actions of each risk are explored. And with the ready of these advanced packaging solutions, HPC and AI are off and running.

Abstract
Authors: J. Hopkins, O. Ansell, R. Barnett (SPTS Technologies) & M. Phenis, D. Pfettscher, R. Peters, M. Sistern (Versum Materials US, LLC) Plasma dicing has shown many benefits over other dicing techniques such as increased die strength, smaller/thinner die and reduced cost of ownership. This dicing process uses the established Bosch Process, with alternating etch and deposition steps to etch through the silicon wafer. The nature of the process means that there will be F residues remaining at completion due to the CFx polymer layer deposited on the wafer surfaces[1]. This can be removed by an O2 plasma however when solder bumps are present and subjected to the same dicing/Bosch process, the bumps can react with F radicals to form SnF2 which cannot be removed by an O2 plasma alone. An additional plasma process can be performed to reduce the F levels further, however, this still leaves F present. Studies are underway to determine whether this is an issue for subsequent steps or indeed whether the presence of F may help solderability[2]. However, in this work, the effectiveness of post-dicing wet cleans to remove the SnF2, and avoid any potential issues, is investigated. Tests were carried out comparing plasma DAG (dicing after grind) processes with different post residue treatments. A screening test was carried out using several different wet etch formulations, and two suitable formulations were identified. Further tests were carried out to optimise the conditions and check the tape compatibility. The F levels, measured by EDX, were reduced to <1% at a level comparable to the control sample (with no plasma dicing). The work has shown that a wet chemistry post plasma dicing treatment is capable of removing F residues and is compatible with the plasma dicing process flow.

Impact of Plasma Dicing Singulation Techniques on Die Breakage Strength and Robustness

Abstract
For all end applications where a semiconductor device is used, there is a constant demand for improved performance under all environmental conditions. One such application, which we all use regularly, is the smartcard chip. This secure microcontroller can be found predominantly in our bank or travel cards and passports, where it may receive much physical punishment in normal usage. The demands for severe robustness criteria for these card-based applications are continually increasing to ensure that the packaged chips are able to withstand more rigorous treatment without breaking. Key to achieving these exacting standards is the singulation of the chips in a way that does not generate any inherent mechanical weakness. The standard blade sawing process has so far met existing requirements but the technology roadmap for such devices has presented new challenges with the deployment of fragile ultra-low k BEOL dielectrics. This has prompted the introduction of laser grooving before dicing to minimise damage to these materials caused by the sawing blade but this, in combination with mechanical dicing can itself cause weakening of the die and a higher risk of failure. This paper will examine the relationship between die strength and some new approaches to die singulation with a strong focus on plasma dicing, in which die separation is achieved by etching the silicon in the scribe lane. As there is no mechanical element we should expect significant improvements in die strength so we will explore the inherent performance with this method as the etching output parameters and masking steps are varied. Additionally, this technique requires that the silicon is exposed in the scribe street, which must be free of metals and dielectrics before etching. Again laser grooving can be used to meet these conditions and we will describe how sequential laser grooving and plasma etch processes affect the die strength and reliability performance versus the more severe test criteria.

Abstract
What an exciting time we live in: self-driving cars, fully electric and always connected to the internet to provide the user a seamless transportation experience. Many announcements around the mobile phone on wheels have been made. Some of the most exciting innovations happening in our cars: cars are becoming our co-pilots as intelligent technologies make them safe and secure, more comfortable, and more autonomous. And with full connectivity the car becomes the new gold mine, a big data collector processing real time traffic data and millions of miles per day. To enable smart, connected and autonomous vehicles, the car’s electronic architecture, its supporting soft and hardware design and release processes must be adjusted. Any failure in the field results in very high cost and liability to the car manufacturer. Requirements for a robust, comprehensive design of a fault tolerant system must be newly formulated. A holistic view of the system failure rate along the supply chain, lifecycle of automotive development and production is necessary. Consequently, robustness, safety, and security of self driving systems must be significantly increased and be monitored continuously. Robust design begins in the early phase of car concepts. Automotive IP centers of excellence have been created, to ensure automotive compliant intellectual property for faster, smarter, low-energy chips reducing risk and development time. Automotive SoC design is meeting the highest safety integrity levels (ASIL) providing ADAS IP as design basis for the new advanced driver assistants architecture. By providing a simulation platform based on the processor models, early virtual prototyping, emulation, and functional verification from modelling to test bench deployment becomes possible. Software experts will be required to ensure fault tolerant, highly reliable, functionally safe and secure software along the automotive lifecycle.

Abstract
The ability to test the quality and reliability of interconnects of semiconductor packages conclusively through non-destructive tests gains importance with increased requirements. Sintered interconnects depend critically on the surface quality of the contact pads and metallic sinter particles. Unstable chemistry of the paste can also cause failures. While X-Ray or acoustic microscopy hardly detect these, thermal methods are sensitive to identify these failures. By TTA measurements the transient thermal impedance Zth is obtained and the thermal resistance Rth is calculated as per JEDEC51-14. But the measurement and data evaluation is time consuming and often requires experts. The relative thermal resistance measurement method is applied in the paper using the automatic tester to evaluate the thermal path and the thermal resistance, wherein the sensitivity and thermal load are not measured but are obtained by thermal path normalization to good samples whose values are known. LEDs are sintered on substrates, measured initially (0-hour quality) and subsequently after hours/cycles of accelerated stress testing (reliability) using the automated TTA tester. The measurement electronics are mounted on a movable 3-axis system to enable use of short cables with low parasitic inductance. To resolve the thermal resistance between the LED die and substrate the forward voltage of the LEDs after current switching needs to be measured well below 10μs. The developed current source allows very fast switching within 100ns and stabilize the detection current within 5μs. In addition an In-Situ tester measures thermal impedance providing additional data to support analysis. In this paper automated TTA test equipment and In-Situ tester are presented which enable to measure the transient thermal impedance and by that identify the thermal integrity of the interconnect after assembly and within accelerated reliability tests. By known good reference samples failures are automatically identified.

Abstract
The wide implementation of electric vehicles is at the moment hindered by (amongst others) the lack of intrinsically safe battery technology that could provide sufficient energy density as well as fast charging for many charge/discharge cycles. The battery industry heading towards solid-state configurations. The key challenges in next-generation all-solid state Li-ion battery technology development are related to the required energy and power densities, fast charging constraints, battery lifetime, and at the same time keeping the cost low by high-volume production. Such technology criteria require superior electrode as well as electrolyte materials (pinhole-free), and processing techniques enabling even advanced 3D designs. We report on innovative materials and 3D architectural approaches that can disrupt current Li-ion batteries, especially combining high-capacity with fast-charging capability. However, newer architectures demand newer processing techniques. A technology researched a lot in this respect is the Atomic Layer Deposition (ALD), which is well-known for its superior material quality and layer conformality over ultrahigh aspect ratio topology. But, in applications outside the advanced micro- and nanoelectronics industry, ALD technology is impeded by the economics of the low film deposition rates. Here, the scalable atmospheric pressure Spatial-ALD (S-ALD) holds the best promise for sufficient deposition rates and large-area roll-to-roll processability, which is key to battery industry. Presented will be the results on high-rate 3D Li-ion battery electrodes using S-ALD, which show charging rates of few minutes. Highlighted will be the development of new high-performance battery electrode materials (in-situ doped) by engineering material properties at the nanoscale. Next to it, we will present about the first-ever S-ALD based solid-state LIPON electrolyte material (<100 nm thick). More about our research and capabilities will be presented during the seminar.

Abstract
Low-dimensional nanostructured materials such as organic and inorganic nanotubes, nanowires and platelets are potentially useful in a number of areas of nanoscience and nanotechnology due to their remarkable mechanical, electrical and thermal properties. However, difficulties associated with their lack of processability have seriously hampered both. In the last few years dispersion and exfoliation methods have been developed and demonstrated to apply universally to 1D and 2D nanostructures of very diverse nature, offering a practical means of processing the nanostructures for a wide range of innovative technologies. To make real applications truly feasible, however, it is crucial to fully characterize the nanostructures on the atomic scale and correlate this information with their physical and chemical properties. Advances in aberration-corrected optics in electron microscopy have revolutionised the way to characterise nano-materials, opening new frontiers for materials science. With the recent advances in nanostructure processability, electron microscopes are now revealing the structure of the individual components of nanomaterials, atom by atom. Here we will present an overview of very different low-dimensional materials issues, showing what aberration-corrected electron microscopy can do for materials scientists.

Abstract
OLED displays are now in commercial production for a range of products from cell phones, tablets, UHD TV’s, and newly emerging applications such as AR/VR headsets and wearable devices. OLEDs offer excellent visual performance, and through the use of phosphorescent OLED (PHOLED) technology, lower power consumption than AMLCDs. OLEDs possess novel features such as transparency and flexibility, which will further increase their market potential over the next few years, and provide a much greater differentiation from current technologies. UDC is a pioneer in the development and supply of phosphorescent OLED technology and materials for both display and lighting applications. In this talk we will review the current status of OLED technology and discuss its potential for exciting new products over the next few years. In addition we would like to report on our recent work to develop a solvent-less, mask-less printing technology for depositing patterned small molecule organic materials to manufacture large area side by side R-G-B OLED displays. Commercial manufacture of large area (TV), side-by-side RGB OLED displays is currently challenged by lack of a suitable methodology for the patterned OLED deposition. Fine metal masks used for mobile OLED displays have not been proven to scale to greater than Gen 8, and scanning smaller shadow masks across a large area has not provided acceptable yield. Inkjet technology has been in development for many years and has yet to provide sufficient performance for volume manufacturing. Organic Vapor Jet Printing (OVJP) has been developed to print patterned OLED layers for large area displays, while avoiding issues arising from the use of fine metal masks and use of solvents. In this presentation we outline how we are ensuring that our PHOLED technology meets the ever more demanding performance requirements of future products, and we will outline how our technology can further improve their performance and lower cost.

Abstract
The POWERBASE project (“Enhanced substrates and GaN pilot lines enabling compact power applications”, 2015-2018) is an EU ECSEL project aimed at demonstrating reliable enhancement-mode GaN-on-Si power technologies, including new engineered substrates, improved materials and optimized device structures. Within POWERBASE, a significant effort has been devoted to the study and demonstration of device reliability, as failure modes and mechanisms of GaN power devices were initially still unknown and testing methods and tools had Si power devices as unique reference. POWERBASE greatly helped in developing an evaluation methodology specifically tailored for GaN: it promoted a detailed study of device failure physics, leading to the derivation of acceleration laws and to the industrial implementation of systems and tools for the assessment of GaN HEMT reliability. Origin of dispersion effects has been identified by means of pulsed and transient characterization of dynamic Ron, and improved devices have been fabricated, showing zero dynamic Ron both at 600 V DC, 150°C and under 20 A hard-switching conditions. Backgating and drain-substrate vertical breakdown effects have been studied, and mechanisms of leakage current have been identified. Due to high electric fields inherent to power switching operation, main failure mechanisms include time-dependent breakdown (TDDB) of the p-gate and of the drain-substrate epi layer, while hard switching may induce hot-electron degradation resulting into on-resistance increase and threshold voltage shift. A lifetime of 55 years 100 ppm (15 years 1 ppm) @125°C has been demonstrated for production-level 70m devices (a 3 X safety margin with respect to JEDEC standard for Si devices). Devices adopting a Schottky contact over the p-type gate can survive 10 years at 150 °C, VG=6.4 V without undergoing breakdown. Concerning GaN-on-SOI devices rated for 200 V operation., a 10 years lifetime was reached at 470 V, 175°C.

Organic Nanofibers as Next Generation Chemical Sensors for Real-time Process Monitoring
Later, Douglas

Vaporsens, Inc

Later, Douglas

Abstract
Early detection of gas phase chemicals can ensure product integrity, and human safety. New types of chemical sensors are being developed that are sensitive, selective and rapid for direct vapor detection of hazardous chemicals. These next generation chemical sensors are based on novel organic nanofiber materials that demonstrate photoconductive and chemiresistive responses to surface adsorption of chemicals. The nanofibers are prepared via self-assembly of building-block, core molecules that are uniquely functionalized with a variety of tail and head groups that enable sensitive and selective binding and electron transfer interaction with different chemical analytes. When placed on a substrate, nanofibers form a porous super-net structure with large surface area and high porosity that can capture target molecules from the air through molecular diffusion and surface adsorption. Upon capture the electron density associated with the nanofiber structures can either increase or decrease resulting in an observable change in electrical conductivity that signals a detection event. For enhanced selectivity nanofibers of different chemical functionality can be deployed in sensor arrays. In addition to selectivity, the nanofiber sensors are also highly sensitive. Certain chemical species have been detected at the low parts per trillion (ppt) level. Nanofiber sensors are particularly sensitive to amines, aldehydes, volatile organic compounds, and toxic industrial chemicals. Vaporsens, Inc. has developed autonomous nanofiber chemical microchip sensors and sensor arrays that can be deployed in small portable detectors and/or fixed distributed networks. Nanofiber chemical sensors can deliver lower limits of detection and faster response times than other commercially available chemical sensors.

Abstract
The manufacturing of power chip technologies, semiconductors and thin-film structures demand quality, precision and reliability regarding the manufacturing processes. Therefore, appropriate in-line ready, integrated and fast characterization methods are required. One of the key requirements for such a system is the ability to gather e.g. precise topography data without the need of mechanically moving parts in order to ensure a fast data acquisition and minimal uncertainties. Within this work an alternative approach based on a white-light interferometer is presented which is designed to comply with these requirements. The interferometer is equipped with a supercontinuum white-light source and defined dispersion over the given spectral range. Due to the known dispersion characteristics, it becomes possible to calculate the surface profile with nm-precision from the phase-varied spectral data. In a two-dimensional approach the surface profile is encoded in one dimension as spectral modulations (z-coordinate) while the second dimension holds information about the spatial distribution of the profile (y-coordinate). The talk explains the data analysis model, calculations of theoretical resolution as well as the experimental setup and its results. Experimental results are presented from samples such as a precision height standard, Si-wafers, MEMS pressure sensors and spin-coated polymer layers. It could be shown that the resolution in the z-coordinate during the experiments was in the order of 2 nm while the resolution in the y-coordinate was in the range of 5 µm. The results of the interferometric measurements where furthermore evaluated with other techniques such as a confocal scanning microscope. Additionally experiments under varying temperature conditions proved a high stability with only 0.15 nm/K drifts. The interferometric method has advantages in fast, in-line metrology applications as it has shown high accuracy and robustness during different experiments.

Herbig, Volker

Abstract
How the CMOS foundry business model runs is well understood: a process technology is developed, a corresponding PDK is created and given to customers, followed by the product development at their side. At this point many customers can be served at the same time. This helps to achieve a high level of fab utilization and to minimize costs and risks. This model does not apply exactly for MEMS – the MEMS business model is different. Process as well as product development are very mostly customer specific and take place simultaneously for different customers within a running foundry production fab environment. On the one hand this is the key to short time to market and to robust production processes as no extra industrialization stage is needed after technology development. On the other hand this is generating various special challenges. This presentation especially talks about those challenges the fab team has to address besides the ongoing CMOS and MEMS production: - tool dedication and tool stability / matching in relation to production and empty costs - advanced metrology concepts including PCM and automatic optical outgoing inspection - process engineering support model in complex and fast running MEMS development projects … and many more. These challenges can be mastered by a deep process understanding and good process integration schemes, both based on intensive collaboration of production and development departments.

Abstract
This presentation will show the challenges seen from the viewpoint of a silicon foundry for analog/mixed signal devices developed and manufactured for Smart Mobility Systems. Smart Mobility Solutions require a wide range of semiconductor solutions. In addition to the main processing units and software solutions multiple sensor interfaces and actuator drivers are required in Smart Mobility Systems which are the interface to the analog world. These interface chips need to be designed on robust and highly reliable semiconductor processes. Such devices have to cope with the harsh automotive environments and often have to include high voltage, non-volatile memory (NVM) and extended temperature ranges on one chip. This needs to be considered not only already by the foundry at semiconductor process and NVM IP development stage but also during manufacturing in automotive certified semiconductor factories. To enable IC designers developing such high reliable products specific foundry support with simulation models which behave as close as possible to the real silicon, but also tools for lifetime calculation based on user defined mission profiles are available as well as memories with built-in ECC are just a few examples what the foundry has to offer in addition to a very close collaboration between the foundry and its clients to ensure highest possible quality with zero incidents during lifetime.

Abstract
Decisions should be supported with verifiable and repeatable performance data. This is true when selecting contactors, test sockets, and probe heads for test. This intent of this paper is to describe and define the data used to specify contactors, test sockets, and probe heads for test. This includes the source methodology and process for developing the lab data describing the performance of contactors, test sockets, and probe heads for test. With this the paper will lead the way to interpret and apply the statistically predicted field performance of the test probe as qualified in a test lab. Presented will be lab data describing the performance of several mainstream probe architectures for contacting Wafer Level Chip Scale Packages (WLCSP). The goal of this paper is to create a common understanding of how to read, interpret, and communicate data for selecting the right probe technology for WLCSP test applications. The paper goes beyond the probes and speaks to other factors that contribute to the overall performance of the contactors, test sockets, and probe heads for test. For example, the probe head housing design and materials used are important aspects that need to be understood for optimized performance. The success of the data-driven probe selection approach is reliant upon the quality of the supplier data. The paper will describe the reports provided including the WLCSP Metrology reports. Focus Content: • Interconnect technologies for improved performance and reliability • The role of material, and material development for higher reliability • Metrology and inspection methods

Abstract
Automotive electronics will show an annual 2-digit growth until 2025. One driver of this development is the increasing number of sensors and actuators in vehicles. This is not only due to additional functions of driver assistance systems, but also due to the demand for lower-emission and more efficient drive systems. New sensor functionalities also require new or diversified sensor designs with partly new components and materials. Here, magnetic materials also play an important role. The results are heterogeneous systems, which require new manufacturing technologies. The classic back-end sensor packaging is facing new challenges. The processing of magnetic materials creates several problems. These are among other things the clean feeding of magnets and a damage-free handling. Adhesive technologies must be adapted to different materials, including a desired short curing time. Despite the processing of roughly tolerated magnetic materials, a high accuracy in the placement must be achieved. Furthermore, the automation concept should enable a high production rate with short cycle times and continuous data tracking during the packaging process. XENON has many years of experience in the development of product-specific equipment, especially for sensor and actuator mass production. In the context of an EU-funded project "IoSense", preliminary studies were carried out for special technologies to produce magnetic sensors, how process safety can be realized together with high quality requirements. Some results will be presented.

Rosina, Milan

Abstract
The market for Li-ion batteries for e-mobility and stationary energy storage is strongly growing, driven mainly by electric and hybrid electric vehicles (EV/HEVs). According to Yole Développement estimates, for the largest Li-ion battery market segment - battery electric vehicles (BEVs) - the market value will reach almost $52 billion by 2023. There is no big technology breakthrough expected in coming years regarding battery cells. The product differentiation will be sought on the battery pack level, by optimizing the battery pack design and its components. The existing solutions from other applications will be modified to fit the EV/HEV requirements, such as low Electromagnetic Interference (EMI) issues and vibration resistance to vibrations. The bigger changes are associated with the battery pack voltage trends towards 800V for BEVs and towards 1,500V for stationary energy storage for grid applications. The use of higher battery pack voltage will impact the choice of electronic components in Battery Management System (BMS) and in car converters and inverters and battery chargers. Silicon IGBTs or SiC MOSFETs rated at 1,200V will be used with 800V vehicle battery packs. The electrical interconnections and connectors and safety devices such as fuses and contactors must also be adapted for higher voltages. The energy capacity of battery packs will continue to increase, resulting in needs for faster charging capability. Ultra-fast chargers providing charging power up to 350kW have already been developed. The power electronic components and systems rated for high currents will enable fast vehicle acceleration. The battery pack as the key element of an electric vehicle is closely interlinked with other elements such as inverters and converters, and motors. The synergies between different sub-systems and mechatronics solutions are sought more than ever, to obtain compact, lightweight and reliable solutions and to reduce the system costs.

Abstract
Wafer demand (including MEMS & sensors, CIS, and power, along with RF devices) for More than Moore (MtM) reached almost 45 million 8-inch eq wafers in 2017. Wafer demand is expected to reach more than 66 million 8-inch eq wafers by 2023, with an almost 10% CAGR2017 - 2023. Numerous megatrend market drivers will contribute to MtM devices’ growth : 5G (wireless infrastructure & mobile), mobile (including additional functionalities), voice processing, smart automotive, and Augmented Reality/Virtual Reality (AR/VR), artificial intelligence. Regarding semiconductor material, although silicon is by far the most dominant, alternative non-silicon-based substrates like SiGe, GaAs, GaN, and SiC are increasing their importance within the MtM industry. Choosing the right substrate technology will strongly depend on the technical performance associated with the megatrends’s requirements, as well as the cost.The presentation will highlight the market trends and the impact on the wafer start for the different wafer substrates.

5G - Who has the most to win (and lose)?
Troadec, Claire

Troadec, Claire

Abstract
5G will totally redefine how the radio frequency (RF) front-end interacts in-between the network and the modem. Indeed, new radio frequency bands, sub-6 GHz, and mm-wave (as defined in 3GPP release 15) pose big challenges for the industry. However, with these challenges comes opportunity to disrupt the market’s leadership. LTE evolution has led to complex architecture in today’s mobile phones, mostly due to carrier aggregation. Meanwhile, RF’s board area and available antenna space have been reduced, leading to a densification trend with more handset OEMs adopting power amplifier modules and implementing new technics, i.e. antenna-sharing between LTE and WiFi. In the low frequency band, the inclusion of the 600 MHz band (for which T-Mobile recently acquired licenses) will pose new challenges for low-band antenna design and antenna tuners. 5G will add even more complexity, with new radio bands released in ultra-high frequencies (N77, N78, N79). Band re-farming (early bands are N41, N71, N28, N66, with more to come) with dual connectivity will also contribute to increasing constraint for the front-end. More densification in front-end modules will be required to enable new band integration, which is the approach followed by Broadcom with its innovative mid/high band module. On the sub-6 GHz side, the current front-end leaders (Broadcom, Qorvo, Skyworks, and Murata) have already begun adapting to these changes. Along with sub-6 GHz, the mm-wave front-end module will completely disrupt the front-end industry, representing a completely different technology mindset that could create a new path to high data-rate access. In our presentation, we will define and analyze the RF Front-End ecosystem for cell phone. We will provide market and technology trends and illustrate who has the most to win (and lose) with 5G.
