Abstract
High Performance Compute (HPC) and AI/ML have been realized by advanced nodes IC and advanced system integration technologies. Device /chip scaling and heterogeneous system integration, eg. TSMC 3DFabric^TM, which consists of CoWoS^®, InFO and SoIC^®, become the twin engine to drive semiconductor technology. Recent new wave of generative AI with LLM showed that HPC and AI/ML have tremendous room for future growth. In the meantime, higher performance compute with higher energy efficiency become even more critical requirements than ever to support the demand. We will continue the scaling of both device/IC and advanced system in classical m-electronics based computing system. Furthermore, photonics-based system integration technology will be added which are complementary to the classical system integration to meet the ever-increasing energy efficient performance requirements for future HPC and AI/ML.

A European 3D Heterogeneous Integration Pilot Line – a Leap ahead to Achieve Technology Leadership

Michael Töpper

Fraunhofer FMD

Abstract
The digital transformation of society and economy creates an increasing demand to transfer, process and store vast amounts of data generated in the context of technologies such as artificial intelligence (AI) and the Internet of Things (IoT). Therefore, future electronic systems like autonomous systems using high-performance computing (HPC) and edge computing systems, sensor-integrated systems and bio-integrated devices will require more and more functions that cannot be managed by a single chip, even if advanced system on chip (SoC) concepts are used. Therefore, advanced 3D heterogeneous integrated systems are the next step of evolution of the IC scaling. To support this a roadmap for required technology developments in heterogeneous integration has been defined by a joint working group of FMD and industry partners with a horizon of 2030 and beyond.It includes lithographical scaling that supports sub µm hybrid bonds pitches. The thermal management of extreme heat dissipation and topological limitations by STCO measures, new materials and new cooling methods. Comprehensive testing of dies to achieve an economically reasonable yield in a complex heterogeneous integration process containing a higher number of dies. To improve the processes and to understand failure mechanisms an appropriate failure analysis has to be codeveloped together to address fails in 3D stacks. Without the possibility to manufacture parts throughout a complete assembly process the full assessment of the impact of these topics is not possible. By looping in wafer or dies of leading-edge CMOS or special technologies like GaN from industry partners or collaborating research and technology organizations advanced processor devices can be realized through an innovative pilot line. Such a pilot line also allows to explore an automotive grade technology along with other industrial applications requiring high robustness. Together with the planned investments into Silicon frontend manufacturing and assembly in Europe as announced e.g. by Intel the heterogeneous integration pilot line at the chip, package and organic substrate level plays a key role to excel the position of Europe as hub for assembly and test.The paper will be presented together with Intel and Siemens EDA.

It is all about Cost of Test? New Duties for Packaging and Test

Ralf Montino
VP PLI
Elmos Semiconductor AG

Abstract
In the past, the processes “Wafer Sort”, “Assembly” and “Final Test” were considered as more or less independent processes with limited duties: Assembly should cover the silicon and the two test processes took care about the functionality of the product. Efficiency increase results from reducing test effort and increasing the parallelism of the test.Today, more and more of the products are customized during the test. This includes flashing customer specific software as well as adjustments at sometimes several temperatures. A more integrated view on these three different steps is necessary. Moreover, there are new demands to the machines. In addition to that, increasing of parallelism is very limited by the handling systems available on the market.

Bare Copper Lead Frame Compatible Die Attach Developments for Automotive Applications

Tony Winster

Henkel Ltd

Abstract
Many semiconductor devices using SOIC, QFP and QFN format are packaged by mounting and wire bonding a die onto metal lead frames using conductive die attach adhesive. Such lead frames have traditionally been fabricated from copper, with a surface of Ag or Ni-Pd-Au (PPF) plating to provide good and stable adhesion and electrical contacts. However, the elimination of the plated finishes would offer significant reduced costs; and also improved reliability, due to higher adhesion of molding compounds to the metal leadframe. To enable this trend, the die attach industry has been engaged in developing new adhesives which offer excellent compatibility with bare copper. In addition, package performance has been improved by formulating for enhanced electrical & thermal conductivity to allow higher power ratings. This has been achieved partly by using increased Ag contents, but mainly by introducing Ag sintering mechanisms. Lastly, package reliability has been improved by optimizing formulations to withstand stresses imposed by higher AEC Q100 automotive requirements, in particular passing 2000 or even more thermal cycles from -55 to 150 Celsius (Grade 0). This has been done by optimizing the polymer chemistry, but also by introducing additives to act as “crack stoppers” to absorb stresses and prevent cracks & delamination from propagating.The paper will describe how a test vehicle was selected to quantify improvements in packages, using automotive industry standard tests. And then go on to describe how changes in chemistry have been introduced to enable significant improvements to package specifications, while controlling and reducing overall package costs, and providing compatibility with materials currently adopted by multiple semiconductor makers, and maintaining capability of being processed using existing equipment and processes.This development work has produced many successes, and continues with a program of further improvements. A “roadmap” showing targeted future developments will be outlined.

Biography
Tony Winster studied Metallurgy & Materials Science before researching materials for high reliability electronics. After some years involved with design and manufacture of Defence/Aerospace packages, Tony joined Ablestik, supporting and growing their respected range of die attach materials. Since Henkel took over Ablestik in 2008, Tony is technically deeply involved with the wide portfolio of Henkel products for semiconductor packages, by supporting new semiconductor packaging developments & “design-in” programs around Europe.

How to Achieve Upcoming Bump Requirements by Optimized ECD Plating Processes

Stefan Pieper
Global Application Manager for Semiconductor Processes
MKS/Atotech

Abstract
Next to Cu-to-Cu hybrid bonding technology for upcoming packaging requirements, the rapid advancements in advanced packaging technologies demand the development of cutting-edge microbump structures with smaller pitch sizes in the range of < 10 µm. Hence, optimized electrochemical deposition (ECD) plating processes will be required to fulfill the needs for this microbump structures. This presentation focuses on the deposition of Cu, Ni-alloys and SnAg, each of them crucial for device miniaturization and performance. We will first give insights into the optimization of the process parameters to allow shape control and the simultaneous deposition of Cu bumps of different sizes on one die (i.e., “hybrid bumps”). Additionally, due to ever decreasing form factors, next generation plating requires Ni-alloy-based barrier layers, which form minimal intermetallic compounds. We will present novel results of possible barrier materials with minimized intermetallic layer thickness. The final part of the presentation focuses on SnAg plating and the optimization of coplanarity and surface roughness, other crucial bump features for smallest, next generation packages.

Optimization of Advanced Packaging Process: Concept of Maskless Dual–Layer Lithographic Patterning

Ksenija Varga

EV Group

Abstract
The integration of advanced packaging features in heterogeneous integration, 3D stacking, and miniaturization of electronic devices is enabled by FO WLP. It offers several benefits, including improved electrical performance, reduced form factor, and enhanced thermal dissipation vs. conventional packaging technologies. The cost–efficient solution to the industry established dual–damascene process in the interconnect formation was investigated in the present paper in relation to the FO WLP application. For this purpose, the concept of maskless exposure patterning of the novel dielectric materials by using two exposure dose levels was set in the DoE.The lithographic patterning was performed by dual–dose exposure of VIA and RDL traces using a single coating and development step without intermediate alignment. The objective was to achieve low resolution, low dielectric layer thickness having half–thickness of the first layer in the dual exposed patterns. A newly developed, low–temperature cure positive tone polybenzoxazoles (PBO) dielectric is cured at about 200 °C and thus is compatible with epoxy materials used in FO WLP packages.The low–temperature cure dielectric was also developed for markets like MRAM, RF, MEMS, and backside RDL applications where the base substrate, other materials, or the device packages themselves are temperature sensitive and require a low–cure dielectric material.At first, an understanding of dose dependency on the dielectric penetration depth in dual–layer exposure needed to be proven. Maskless exposure technology offers a simple exposure dose/wavelength/focus matrix. The parameters can be easily adjusted via recipe enabling efficient process evaluation. The contrast curve proved the linear behavior of exposure dose vs. removed thickness layer after the development. By patterning with the most optimal dual–exposure parameters, the resolution 3.8 µm (via within via opening), min. dual–layer thickness of 8 µm (first layer thickness 4 µm) after cure was proven by SEM images and stylus profile measurement. The spectral reflectance images reveal uniform film thickness (FT) distribution after spin coating, while the FT non–uniformity increased after the cure and the development processes.In conclusion, the newly established concept can support continuous efforts of the BEOL semiconductor industry in the total cost–of–ownership optimization.

High Efficiency Cleaning for Permanent Bonding-Based 3D Applications

Donald Dussault

ProSys, Inc.

Abstract
Bond defectivity due to particle generated voids in the bond interface is a limiter in direct bonding yield. This issue is growing exponentially with the reduction in interconnect pitch making the killer defect particle size smaller and smaller. An effective cleaning process should remove all contaminates (if removeable), but must not add particulate or damage the substrates to be cleaned. The cleaning method should also be applicable to singulated die on tape frame and address the die edge/kerf contamination without displacing the die. In this presentation we will present a unique Megasonic Cleaning device that meets these emerging cleaning challenges. We will also present pre-bond cleaning results achieved with this device in several direct bonding applications evaluated both through classical particle detection (SP-X) as well as actual void detection with acoustic microscope. We will further describe how this device can be applied to the evolving cleaning challenges in W2W and D2W Hybrid bonding process sequences.

An Overview of Silicon Carbide Packaging for Power Electronics

Ashley Lobo

Automotive

Abstract
There has been a rise in the use of Silicon Carbide (SiC) in Power conversion applications in the photovoltaic, automotive and wind industries due to its low switching losses. This enables higher switching frequencies compared to conventional silicon devices. Recently there has been a large-scale adoption of SiC because of manufacturing breakthroughs resulting in cheaper semiconductors which can be produced on a relatively larger scale. With the shift from 150mm to 200mm wafer size, the economies of scale will be enhanced even further, leading to even greater adoption of SiC in newer industries. While SiC properties make it an ideal replacement for Si in power conversion and power electronics, to extract the full potential from SiC, innovative packaging will be required because most of the current packaging is based on Silicon and not SiC. This presentation addresses the trends, innovation, and challenges in the manufacturing of power module packaging solutions like interconnections, encapsulation, die and substrate attachment, baseplate, etc. The presentation will also analyze the manufacturing implications of new packaging topics of SiC, such shift to diode-less SiC MOSFET module from antiparallel diodes. Case studies on newer innovations like the 4-lead TO-247 Kelvin source pin by different SiC manufacturing companies will be discussed. Supply chain players of different components and their business models including product portfolio of different manufacturers, trends, and comparison of different substrate materials as well as system level trends will be evaluated. Manufacturing of newer module packaging such as the use of dual side flex foil for interconnections, substrate attachment by silver sintering of the die or newer substrates for SiC like Si₃N₄ and AIN will be the focus of analysis. Key requirements and innovations in packaging of SiC semiconductors from various industries like Electric Vehicles, Wind, and Photo Voltaic have been identified.AbbreviationsSiC- Silicon CarbideMOSFET- Metal oxide semiconductor field effect transistors
