Increased use of chemical process control taking as a path to increased sustainability

Irene Popova

Nova Ltd

Abstract
As a responsible participant in the modern economy, semiconductor industry shares a burden to Reduce, Reuse and Recycle, as much as possible. Our customers constantly feel this ever-increasing pressure but feel reluctant to fully embrace it. Simply because with it comes sharp need to balance improving process yields and device reliability, while controlling process costs, and optimizing resource utilization. Intense use of chemical materials in the semiconductor process flow is a given and often – aggressive replacement of process chemicals is a safest solution, offered in cases of process variations, unexplained process excursions. This invariably leads to massive amounts of process waste, burden shouldered by our communities and our environment. This is a perpetual challenge in our industry. So – why have not we solved it and is there a sustainable answer to this problem? We, at NOVA, believe that the answer is increased use of chemical process control. Process control not only allows to reduce natural process variation, improving overall process stability, but in case of chemical process metrology, directly translates to the reduced chemical consumption and optimized chemical lifetimes. With improved process stability and materials optimization, comes possibility to streamline chemical utilization in the fab, while maintaining process complexity, dictated by new integration schemes and material solutions. Electrochemical deposition is a particular sector, where applications at both local interconnect damascene and advanced packaging are intense chemical users, with high refresh rates and often, short bath lifetimes. At both of those instances, implementing unique solutions like DMR (Direct Metal Replenishment) or traditional chemical analyzers enables significant improvement of cost of ownership and reduction in waste generation – a win-win for the customer, environment, and process stability. Outside of the optimizing process chemicals, we believe that implementing more control solution on the incoming materials quality side allows to prevent excursions and process deviations from happening, leading to even more optimized use of resources.We will discuss several use cases where improved chemical process control by NOVA chemical analyzers shifts the scales sharply in favor of higher process yields, minimizes excursion risks while reducing the environmental impact of the semiconductor process flow.

Study of Diamond Coated Wire (DCW) slicing technique process parameters impacting high grade Semiconductor Wafer quality, mainly for Warp, Total Thickness Variation (TTV) and Nanotopology (NT)

Carlo Zavattari

GlobalWafers

Abstract
The study describes in detail how the technique of slicing high grade semiconductor wafer with Diamond Coated Wire (DCW) drives mechanical wafer quality, how both the slicing process parameters and tool set-up impact the quality and how one can take advantage in tuning those parameters to properly change wafer shape according to the needs.For as cut wafers, mainly focus is on warp (warpage, wafer shape,), TTV (total thickness variation), and waviness, which is a prediction of wafer behavior at the end of the line (post polishing), where NT (nanotopology) is measured. NT is a surface variation over a small area, and it can be considered as a non-planar deviation within this area, and it can be seen as a local warp. Each of these wafer parameters are driven by different saw parameters, and the optimization of the wafer ones is descending from an equilibrium and “compromise” in the saw set-up. This means there is no optimum slicing process, but there are specific processes to fulfill different wafer requirements.The major slicing parameters are wire and coolant. Being the wire the cutting agent, its characteristics in terms of diamond grain distribution, adhesion (plating or bonding) and shape are determining the cutting ability and precision. Coolant contribution comes from its property to enhance the silicon swarf removal from the wire and the way it is distributed inside the cutting room determines the efficiency of removing not only the swarf but also the heat generated during cutting.The saw set-up includes wire management, coolant distribution, feed unit and wire guide shape. New generation saws, born in the 2010’s, have been built to optimize the DCW slicing process, which is slightly different from the slurry one (original process for wire sawing), and for some extent more critical, since the DCW is more fragile and brittle. To guarantee the proper cutting ability the new wire management needs to provide double (or more) top wire speed and acceleration compared with the past. Water and surfactant (coolant) are used instead of slurry. The coolant has a different scope compared to slurry: it is not used for cutting but for cooling and for removing the silicon swarf during cutting; thus, coolant distribution needs to be different and more focused than what is done for slurry. Feed unit and wire guide shape also need to be optimized to handle the new type of wire and its different cutting ability.This study is strictly referring to semiconductor silicon

Adding Automation (SECS/GEM) Capabilities on Legacy Equipment

Nirav Thakkar

Einnosys Technologies

Abstract
OverviewSEMI's SECS/GEM standards have become the de-facto communication protocol for semiconductor equipment to interface with factory systems. These standards prevent human errors in selecting incorrect recipes and enable equipment performance monitoring. However, many smaller fabs and assembly, test, and packaging factories still have legacy equipment without SECS/GEM capabilities. Adding SECS/GEM functionality to such equipment has posed challenges due to discontinued OEM support and expensive upgrades. This hinders factories from achieving improved yields, cycle times, and automation benefits.Plug-n-Play SECS/GEMTraditionally, SECS/GEM capability must be purchased from the OEM and integrated at the source code level. Some companies offer "black box" solutions, but they have limitations and potential side effects. A better approach is using equipment PC peripherals to add SECS/GEM capabilities. Data can be extracted from the equipment's controller GUI using computer vision and AI technologies, and remote control commands can be sent through the equipment PC's mouse and keyboard interface.Enhanced Automation CapabilitiesThe peripheral-level approach allows for safer integration without side effects. Additionally, AI/ML and computer vision technologies can enhance automation capabilities beyond SECS/GEM standards. This includes sending images of wafer measurements or inspections, enabling Robotic Process Automation (RPA) on the equipment, and allowing remote desktop access to equipment without a network connection. Implementing this approach overcomes challenges associated with legacy equipment and unlocks automation benefits.

Key ingredients for Developing Superconducting Quantum Processing Units at Scale

Thorsten Last
Director
Orange Quantum Systems B.V.

Abstract
When fully developed, quantum computing will offer novel ways to solve problems intractable by classical means of computing. The potential to transform the paradigm of computing makes it a strategic technology for the world’s leading economies ([1] and references therein). But to bring the technology to this level of readiness, several developments and breakthroughs in quantum computing design and architecture are still required. Quantum processors need more and better qubits for passing the usefulness barrier for this technology. Still, even current computational ecosystems of classical supercomputers combined with general-purpose but error-prone demonstrators already provide a steady increase in computation capabilities. And although the sole unifying platform for qubit implementation is not yet apparent, superconducting qubit technology has emerged as a leading candidate for realizing a scalable platform. The current figurehead of this qubit technology is the so-called transmon qubit.However, current lab-based approaches in transmon fabrication and testing are not scalable and have already started to limit the rapid development of the field. Novel solutions are required to tackle the approaching bottleneck. Therefore, here we present aspects of how to move superconducting qubit manufacturing and testing from small-scale laboratories to large-scale fabrication facility environments. To enable this transfer, two key ingredients are demonstrated: (i) A foundry-compatible fabrication process of superconducting qubits that can benefit from the advanced process control in industry-scale CMOS fabrication facilities, and (ii) an acceleration of testing through switching techniques and parallelization of benchmarking tools with end-to-end data analytics. Although some of these elements have been explored independently, co-development is crucial to enable an efficient scalable development cycle for quantum computing technology. A full development cycle consisting of scalable manufacturing, testing, and benchmarking will enable the large-scale fabrication and control of quantum computing devices and thus pave the way to commercial quantum advantage.

Energy-Efficienct Compute For A Sustainable Future

Gaurav Gupta
VP Analyst
Gartner

Abstract
Energy consumption is one of the most relevant issues for information and communication technologies (ICT). New workloads for compute-heavy simulations/forecasting are demanding performance increases that can be achieved only with increasing levels of parallelism (and, hence, power consumption) to deliver the required capabilities. With emerging large language model (LLM) applications, such as generative AI, that require massive workload clusters, this challenge will only become a bigger concern. With worldwide ICT energy demands increasing at a rate higher than global electricity production, resources for generating electricity will feel the pressure. Hence, ICT energy consumption is becoming a key issue for a sustainable future.For more than 50 years, the semiconductor industry has managed to maintain the cadence of Moore’s Law for improvements in integrated circuit performance, and it has driven computing costs (performance per watt) down. That is all changing. Over the past 10 years or so, the cadence of Moore’s Law has slowed down, with the result that the semiconductor industry can no longer deliver improvements in device scaling and power efficiency at historical rates. This presentation will focus on various innovations in the semiconductor industry for energy-efficiency compute to ensure a sustainable future.

Ai-Based Defect Classification: an Accuracy and Efficiency Boost

Bart Van Poucke

Robovision

Abstract
The growing complexity of Integrated Circuit (IC) architectures poses a challenge for accurate imaging and detection of defects. Furthermore, the shift towards high-mix low-volume production schemes presents challenges for cost-effective automated inspections. Although the introduction of Automatic Defect Classification (ADC) solutions mitigates the heavy load on human resources in fabrication, there remains an application mismatch between low classification accuracy and the high purity needs. The presented Deep Learning AI-based classifier increases accuracy (intelligence) in defect classification for both existing and newly-found defect types from an assortment of wafer designs.During semiconductor manufacturing, classifications that do not meet the required confidence level (class threshold) for a specific class will be labelled as “Unknown” and are presented to the operator for manual classification.The result is a continuous refinement of the model providing higher classification accuracy over a broader range of class types. An ADC solution is no different than any other tool on the manufacturing floor. Just like an etcher or a polisher, ADC executes a recipe and produces a result. The AI-ADC solution is built with an intuitive UI designed to guide you through the natural steps of collecting/managing samples, configuring image detection, setting up classifiers, and verifying the results. The biggest difference versus training a human however, is that you only need to train a single ADC system, as opposed to a small army of human reviewers.Defects in the complex chip manufacturing process are specific to the process layer and may depend on the particular IC being fabricated. As such, recipes should either be capable of handling the variation, or they should be customised to the specific layer or specific IC. Rule-based ADC struggles to generalise defects over ICs and process layers due to its nature and consequently requires a consistent customisation effort by highly skilled specialists.In the process of manufacturing chips, different layers of interconnects in the Back End Of Line (BEOL) can have distinct design rules that result in varying dimensions of defects. However, the characteristics of the defects themselves are comparable across the different layers. Consequently, AI-based recipes can be generalised across multiple layers and multiple ICs, which can significantly increase the efficiency of recipe creation and tuning.

Manufacturing next generation power devices – how temporary bonding allows wide bandgap power devices to go vertical.

Elisabeth Brandl

EVG

Abstract
Wide bandgap power devices are experiencing a strong growth, especially SiC and GaN technologies are in the front seat. Reason for that growth are mainly electronic vehicles and renewable energy but also the general need for efficient, low loss power conversion. However, both SiC and GaN still face challenges. For SiC the transition to 200mm wafers is still not implemented in the extent to satisfy industry’s demand. GaN is facing technological challenges where only lateral devices with a therefor limited breakthrough voltage are commercially available yet. A novel approach is the transition to vertical devices where a higher breakthrough voltage and therefore wider application window can be expected.For better thermal management temporary bonding was already implemented for lateral GaN power devices, but for vertical GaN power devices grown on foreign substrates, temporary bonding is an essential and critical block in the manufacturing chain.SiC power devices on small wafer sizes not necessarily need temporary bonding as mechanical support during thinning because of SiC’s robust nature. Going to 200 mm wafers temporary bonding is also a necessary process enabling thinning and backside processing.In the presentation the different process flows for wide bandgap power devices with their unique challenges will be discussed and an outlook on the manufacturability on future devices will be given – a focus will be the process compatibility of the temporary bonding during growth substrate removal for GaN power devices and thinning for SiC power devices as well as metal contact formation will be reviewed.This project has received funding from the ECSEL Joint Undertaking (JU) under grant agreement No 101007229.

Enabling smart manufacturing and new processes for fab automation – Equipment control tools for longer machine lifetime and material rescue

Natalie Schulze
Product Manager Equipment Control and Integration
Kontron AIS GmbH

Abstract
Special tools in the software equipment control can help prevent failures, step in sooner or limit the damage. Depending on type of failure and the wafer and tool type, the overall damage value can reach up to hundreds of thousands of dollars.The efficient management and monitoring of equipment play a vital role in minimizing downtime, reducing maintenance costs and maximizing productivity. Equipment control software provides an array of functionalities, including real-time monitoring, predictive maintenance, and intelligent decision-making capabilities, all of which contribute to prolonging the lifespan of machines and enabling effective material rescue.To ensure longer machine lifetimes, equipment control software offers real-time monitoring capabilities that allow operators to track the performance and condition of machines continuously. By analyzing data collected from various sensors and components, potential issues and anomalies can be detected at an early stage, enabling proactive maintenance interventions. Timely identification of impending problems helps prevent major breakdowns and costly repairs, ultimately increasing the overall lifespan of machines.Moreover, equipment control tools incorporate predictive maintenance features that utilize advanced algorithms and machine learning techniques. These capabilities enable the software to analyze historical data, predict future failures or malfunctions, and recommend optimal maintenance schedules. By implementing preventive measures based on these insights, organizations can minimize unexpected downtime, reduce maintenance costs, and extend the operational life of their equipment.Another crucial aspect of equipment control software is its ability to support material rescue efforts. In manufacturing processes, scraps, or defects often occur. By leveraging intelligent decision-making capabilities, equipment control tools can identify salvageable materials, redirecting them for reuse or repurposing. This not only helps reduce material waste but also promotes sustainability and cost-effectiveness within production cycles.To address the security concerns, a set of recommended security measures that should be integrated into equipment control systems compliant with E187 and E188 is also necessary. These measures encompass various layers of defense, including network security, access controls, encryption, intrusion detection systems, and incident response mechanisms. Moreover, it emphasizes the importance of ongoing monitoring, vulnerability management, and security awareness training for personnel involved in equipment control system operations.In conclusion, equipment control software plays a critical role in optimizing equipment performance, prolonging machine lifetimes, and facilitating material rescue. Real-time monitoring, predictive maintenance, and intelligent decision-making capabilities all contribute to achieving these goals. By implementing these tools, organizations can ensure efficient operations, minimize downtime, and contribute to a more sustainable and cost-effective and secure SEMI compliant manufacturing ecosystem.

Enabling smart manufacturing in semiconductor fabs using predictive design and process insights

Srividya Jayaram

Siemens Digital Industries Software

Abstract
As semiconductor fabrication pushes the boundaries of physics and chemistry, machine learning (ML) is sought to tackle complex design and process interactions. For advanced nodes, robust process control is essential early in development cycle due to the complexity of the process flow. Additionally, during the first stage of a new product introduction (NPI) in the fab, design validation is a crucial step with only minimal margin of allowed error. Rapid advancements in ML and availability of big data have allowed semiconductor fabs to analyze large amounts of both design and fab data, to make informed decisions and enhance processes through pattern and trend identification. In this talk, we will present the details with results on using Calibre® Fab Insights tool to enable smart manufacturing in three major applications areas within the fab, that can ultimately help in accelerating the yield ramp. First area is process monitoring (PMON), where we leverage usage of design and process features to prescribe product dependent process adjustments which in turn help accelerate NPI, improve automated process control (APC), provide actionable insights to identify parameters that most impact any given process step. The second area is tool monitoring (TMON), where the ML model can help early detection of tool drifts, that cause tool to go out of control (OOC), by providing alerts to perform a predictive maintenance. This can reduce the process/tool tuning time to bring them back to spec after a preventive maintenance (PM) cycle. The final area of application highlighted is virtual cross metrology (CM) where a digital metrology twin is created that enables prediction of metrological measurements at every intermediate step along with wafer maps. Additionally, root cause analysis (RCA) to highlight non-intuitive and overlooked parameters that systematically may contribute to yield results can be obtained. These applications and use cases pave the way to use smart manufacturing concepts to decouple, isolate and quantify the individual influences each step in the fab imposes on different products at various stages of the fabrication flow. This ultimately helps provide an accelerated yield ramp curve that translates into cost and time savings.

Cost-Efficient Wafer-level SOI Process for Thermal Stability and Area Shrinkage in 3D NAND Peripheral Circuit

Seungmin Lee

Sungkyunkwan University

Abstract
In this study, we propose a low-cost implementation of silicon-on-insulator (SOI) through wafer-level processing. In the foundry industry, the FDSOI technology, which was once in competition with bulk FinFET, is currently used only in limited technology nodes due to its high wafer unit price. Using the proposed process integration, SOI can be achieved with just the addition of one photo mask, effectively solving the cost problem, which is the main drawback of SOI. However, this technology is implemented by removing the sacrificial film through the shallow trench isolation area and replacing it with an insulator, which results in the need to consider process margins during the layout design stage. Therefore, rather than using it in a foundry where design and process are separated, it is appropriate to use it for a memory device that is easy for DTCO as the design and process are conducted in one company.Considering these factors, we aim to utilize the proposed SOI technology in the peripheral circuit of 3D NAND. In the era of big data, NAND Flash, which traditionally served as a storage device with relatively low I/O speed, now faces increasing demands for higher I/O speeds. The cost-effective SOI presents a promising alternative in this regard. Particularly in 3D NAND, where the cell process occurs after the formation of the peripheral circuit, the high thermal budget during cell processing can negatively impact transistor performance and pose challenges for achieving high I/O speeds. By utilizing SOI, a thermally robust peripheral circuit can be realized, as the insulating film beneath the single-crystal Si acts as a physical barrier, preventing dopant thermal diffusion. The stability of the thermal budget was verified through dopant diffusion TCAD simulations, evaluating parameters such as DIBL and subthreshold swing, under high-temperature and prolonged annealing conditions.Furthermore, SOI offers effective scaling of the peripheral area. Because the program-and-erase operation of 3D NAND requires a high voltage of 20 V or higher, a charge pump with a large area is required. Additionally, as 3D NAND is stacked, the parasitic capacitance between WLs and that between the WL and the string increases. As a result, the area of the charge pump tends to increase. The top Si, insulator, and Si bulk structures can be formed in parallel beneath the existing MOS and MIM capacitors, resulting in a potential capacitance increase of up to 41% within the same area.

Smart data sharing enables semi-ecosystem collaboration on the path to net-zero

Chris Han-Adebekun
VP of Business Development
Athinia Technologies

Abstract
It is well recognized that throughout the entire semiconductor value chain, Scope 3 emissions make up more than 40% of the carbon emissions-often invisible to upstream and downstream players. Lack of a trusted data platform for transparency and traceability is a big hurdle currently. On the path to net-zero, the semiconductor industry needs to first align on a mechanism to identify emission hotspots along the value chain. Therefore, the shared challenge of improving emission reduction requires the collective effort of the entire community and for us to have an aligned vision and a strategy to prioritize and collaborate.In this session, we will discuss how a secure data collaboration platform can help the industry to overcome data siloes following standards adopted by Semiconductor Climate Consortium (SCC) members, including the Greenhouse Gas (GHG) protocol. We will also examine how data from certified sources can provide an accurate and comprehensive overview, and how data and methodologies can be selectively shared with upstream and downstream partners while ensuring data ownership. With more available data across the ecosystem comes improved visibility of the entire value chain and the ease of identifying emissions bottleneck, generating actionable insights that help us maintain the industry's long-term viability.

Building A More Sustainable CuCMP Process: Selective Copper Removal & Recovery

Cameron Lippert

ElectraMet

Abstract
Challenge: (1) Current Cu-CMP processes are unsustainable due to the large amounts of waste copper that end up in the wastewater, millions of kgs per year combined (2) Complicated wastewater matrix makes treatment to remove copper to meet discharge compliance burdensome and expensive, (3) Evolving Cu-CMP chemistries that produce copper laden wastewater that is unable to be treated with conventional treatment solutions. Urgency: (1) Pressure to meet ESG targets of recycling water and waste as well as decarbonization, (2) Copper demand outpacing supply and Cu-CMP produces a large amount of recoverable copper waste, (3) Increasing cost to treat more complex CMP slurry matrices, (4) Current solutions for treatment rely on chemistry or consumable media which are subjected to an unpredictable supply chain.Solution: Electrochemical device (chemical-free) to selectively remove AND recover copper form complex streams without damaging the slurry mixture.ElectraMet® is an electrochemical system for targeted metals removal from process and wastewater streams. This system uses an automated process to treat CuCMP rinse/wastewater directly at the customer site by removing and recovering Cu as high purity metal sheets while achieving discahrge limits (sub mg/L) in the wastewater. This process leaves the rest of the slurry mixture in tact potentially allowing the slurry mixture to be reused. By electrochemically recovering copper, ElectraMet has proven to be a simple and efficient on-site solution for CuCMP wastewater treatment, even in the presence of other chemicals. ElectraMet does not rely on chemicals for its treatment, the overall operation is simpler, and the footprint is much smaller, than other on-site options.ElectraLink™ is an assurance program that provides an additional layer of support by allowing ElectraMet engineers to monitor your system on your behalf in real time. ElectraLink uses a secure cellular connection to run remote diagnostics, send daily system reports, and can protect you from costly downtime. With ElectraLink, historical trends and changes to the water treatment process can be tracked in real-time including monitoring of alarm codes, tank levels, pressure drops, valve positions, pH, and ElectraMet cartridge diagnostics. The ability to actively monitor these process conditions means you can avoid possible upset conditions that result in tank overflows, lack of proper water treatment or impurity removal, or flow-limiting pressure conditions.
