sustainability

At SEMICON Europa 2025, the Executive Forum programs brought together experts from across the semiconductor value chain to address two critical challenges shaping the industry’s future in Europe: the transformation of the automotive sector and the pursuit of smarter, more competitive manufacturing.Smart Mobility in a Changing MarketKnut Krümmel, Senior Partner Automotive at Porsche Consulting, set the tone with a stark question, “Are we facing a Detroit scenario in Europe, especially in Germany?” – a reference to the decline since the 1990s of the famous “Motor City.” He pointed out that all three of Germany’s giant OEMs, Volkswagen, Mercedes-Benz and BMW, are rapidly losing market share in China in the face of a destructive price war, and have suffered large declines in reported earnings. Krümmel outlined four strategic imperatives for Europe’s auto industry: reduce complexity and increase standardization, become software-defined, design regulation that supports innovation, and build stronger partnerships across the ecosystem. He emphasized, “A new mindset is needed—people need to be hungry to win and prepared to suffer in pursuit of victory.”Knut Krümmel, Senior Partner Automotive, Porsche Consulting GmbHAndreas Aal, Head of Semiconductor Strategy at Volkswagen AG and Chair of Europe at SEMI Smart Mobility Global Automotive Advisory Council (GAAC), introduced a proactive approach to redefine the market. He shared Volkswagen’s vision for mobility-as-a-service, exemplified by its roboshuttle pilot in Hamburg. “It is very difficult for a traditional OEM to go into the full digital services world. But this is what we want to do,” said Aal.Andreas Aal, Semiconductor Strategy Volkswagen AG and Chair of Europe GAAC, VolkswagenJan-Philipp Gerhmann, Vice President of Marketing and Strategy for Automotive at NXP Semiconductors, added that the traditional value chain is being upended. The industry is shifting from a hierarchical supply chain to vertical integration, with companies like Tesla designing their own chips. Gehrmann introduced NXP’s CoreRide platform, a modular “skateboard” architecture enabling plug-and-play Advanced Driver Assistance Systems (ADAS) and infotainment features for future vehicles.Jan-Philipp Gehrmann, Vice President of Marketing Strategy, NXPA perspective on the future of semiconductors in autonomous vehicles was provided by Dieter Hoffend, Business Director for Automotive at imec: “For autonomous vehicles, you need a higher-end compute capability, which needs a transition to smaller nodes – and that is very costly. In fact, semiconductor companies will not want to commit volume to automotive customers for their most expensive leading-edge ICs. This means that a chiplet architecture will be the most cost-effective approach for vehicles, and will provide the greatest supply chain resilience. To support this, imec’s vision is of an open chiplet marketplace of heterogeneous chiplets which are interoperable.”Dieter Hoffend, Business Director Automotive Sector, imecAchieving End-to-end Manufacturing ExcellenceThe Executive Forum then shifted to a discussion of smart semiconductor manufacturing. Giovanni Notarnicola, Partner at Porsche Consulting, highlighted the untapped potential of AI in fabs. “AI requires massive amounts of data—but fabs often don’t own or control their data. And second, AI talent doesn’t typically reside in semiconductor companies,” said Notarnicola. His recommendation: “AI is not an IT issue—it’s a cross-functional technology. Isolating AI in the IT department is an old-fashioned view which will deter AI talent from joining the industry.”And Notarnicola encouraged the industry to leverage the new white paper, From Hype to Impact—Realizing AI's Potential in Semiconductors Manufacturing, produced by SEMI End-to-End Smart Manufacturing Group, which provides an in-depth report on the application of AI in semiconductor fabrication. Giovanni Notarnicola, Partner, Porsche ConsultingOliver Aubel, Corporate Lead for Automotive Solutions at GlobalFoundries, echoed the opportunity. “We have 1 billion sensors in a fab, but 30% of the signals are statistical noise. AI could help us make better sense of the data.”Oliver Aubel, Corporate Lead for Automotive Solutions at GlobalFoundriesA session on smart manufacturing brought to light other proven methods for improving the performance of fabs. Dr. Holland Smith, Director of Data Science at INFICON, described fab control technology that INFICON had helped STMicroelectronics to deploy. As Thomas Gimmig, Director for Industry 4.0 at STMicroelectronics, said, “Our model was a highway control room – a place where a single person controls 220km of road monitored by 400 cameras, and handles one alert every three minutes on average. This is only possible with a huge amount of automation.”Left: Thomas Gimmig, Director for Industry 4.0 at STMicroelectronics; Right: Dr. Holland Smith, Director of Data Science at INFICONAt STMicroelectronics, the new fab control room mimics this model, automating anomaly detection and problem solving. Smith described how the system will not be limited to detecting and handling anomalies which have already occurred. “There is a plan to look ahead at problems which could emerge in future, and to configure it to make proactive suggestions which will prevent anomalies from occurring in the first place,” said Smith. Jamie Potter, co-founder and CEO of Flexciton, showcased how intelligent scheduling tools based on real-time fab capacity are transforming operations. “In the modern fab decisions must be made more frequently, with more intelligence and with fewer people. And that is why fabs need to be made more autonomous,” said Potter.Jamie Potter, CEO Cofounder, Flexciton Ltd“Our tool is based on a dynamic capacity model of the fab, so WIP optimization is based on knowledge of what the fab can actually do now, rather than – as is normally the case in fabs today – on an abstract algorithm which is derived from operational results observed in the past.” Potter said. Robert Wallace, Solutions Architect at Seagate, which has deployed the Flexciton technology, confirmed the impact: “We increased throughput without increasing cycle times, and saw a 30% drop in deviations from forecast completion times.” Robert Wallace, Solutions Architect at SeagateAntoine Amade, President (EMEA) of Entegris, emphasized the importance of benchmarking to guide performance improvements: “We have a robust library of fab case studies. These benchmarks can become the foundation for best practices.” Antoine Amade, President (EMEA) of EntegrisRegulatory Burdens and Regional Challenges In a panel session, the discussion turned to the issues that European semiconductor manufacturing faces in particular. Herbert Blaschitz, Executive Vice President of Advanced Technology Facilities at Exyte, put a strong emphasis on the drag that European regulation imposes on the construction of new fabrication plants: “There is three times more paperwork to complete in Europe than in Asia.” Blaschitz made the contrast with Taiwan, “where they have standard codes of regulation specifically for a wafer fab. In Europe, we have regulations for skyscrapers, we have regulations for building family homes. But we have nothing for wafer fabs.”It could be worse for companies building all new fabs. According to Stephen Rothrock, President and CEO of ATREG, “We are affected by permits and politics most of all when trying to push through the repurposing of fabs.”From Left to Right: Mark Puttock, Sr. Director - Technology and Innovation, Entegris; Giovanni Notarnicola, Partner, Porsche Consulting; Stephen Rothrock, President/CEO, ATREG; Jean-René Lèquepeys, Deputy Director and Chief Technology Officer, CEA-Leti; Herbert Blaschitz, Executive VP of Advanced Technology Facilities, Exyte; Oliver Aubel, Corporate Lead Automotive Solutions, GlobalFoundriesSustainable Manufacturing Practices: A Source of Competitive Advantage?The forum ended with a debate on the value of and problems with Europe’s commitment to sustainability. As Mark Puttock, Senior Director for Technology and Innovation at Entegris, acknowledged concerns that sustainability practices could raise costs and reduce process efficiency. But Jean-René Lèquepeys, Deputy Director and Chief Technology Officer at CEA-Leti, countered: “sustainability can be a competitive advantage. For instance, the industry is under pressure to eliminate PFAS from its processes. CEA-Leti is working on this problem, and the whole world is looking for a solution.”The event concluded with a moment of celebration: Ilya Zabelinsky, Co-founder of the International Subfab Research Labs (ISRL), won a diamond prize sponsored by Nanores Lab,Left: Jakub GawczyńskiJakub Gawczyński, Head of Nanores Lab; Right: Ilya Zabelinsky, Co-founder of the International Subfab Research Labs (ISRL)On behalf of SEMI, we extend our sincere gratitude to the speakers, sponsors, and participants who contributed their expertise and vision to the programs at SEMICON Europa 2025.SEMI ContactAna Bernardo, Senior Manager of Technology Programs SalesEmail: [email protected]

The GENESIS EU project is reshaping how Europe thinks about semiconductor manufacturing. Its goal is simple but ambitious: reduce usage of harmful chemicals from chip production, cut emissions and waste, and make the industry more circular and resilient.Launched on 1 May 2025, GENESIS – GENerate in Europe a Sustainable Industry for Semiconductor – is a research and innovation project co-funded by the European Union through Chips JU and its participating member states. In addition, Swiss partners are supported by the Swiss State Secretariat for Education, Research and Innovation (SERI).Coordinated by CEA-Leti in Grenoble, GENESIS brings together 58 partners from across the semiconductor value chain: materials and chemistry suppliers, equipment manufacturers, semiconductor fabs, research and technology organisations (RTOs), universities, small and medium-sized enterprises (SMEs), recycling specialists and communication experts.

The CxO Summit at SEMICON Europa 2025 spotlighted Europe’s ongoing efforts to build a resilient and globally competitive semiconductor industry, while calling for greater ambition, speed, and unity in execution. Following global disruptions with the automotive supply chain crisis, the European Union launched a continent-wide strategy through the EU Chips Act. While the Act has already spurred significant developments, including construction of the new ESMC fab in Dresden, Europe remains far from its goal of achieving a 20% share of global semiconductor production by 2030. The CxO Summit, part of the SEMICON Europa event in Munich, provided an opportunity for industry leaders to share ideas about how to catalyze the next phase of the European industry’s growth.Ajit Manocha, President and CEO of SEMI opened the summit by describing today’s industry landscape with one word: “unprecedented.” Manocha said, “The global growth of the industry is unprecedented, with 107 new fabs set to come online by 2028, but the uncertainties are unprecedented, from geopolitics to the talent shortage to environmental concerns. So we need unprecedented solutions.” Ajit Manocha, President and CEO, SEMILaith Altimime, President of SEMI Europe echoed the mood of uncertainty, describing Europe as caught “in a perfect storm.” Altimime said, “As we face a combination of internal challenges and intensifying external competition, collaboration is not optional — it is mission critical.” Laith Altimime, President, SEMI EuropePierre Chastenet, Head of the Unit for Microelectronics and Photonics, European Commission, highlighted the tangible progress made under the EU Chips Act. “We now have a proper toolbox to handle a future crisis in the supply chain. The Chips for Europe initiative has led to the creation of five pilot lines for advanced technologies such as FD-SOI and wide bandgap semiconductors.” Chastenet added, “Europe must now capitalize on its strengths, from materials and equipment to design tools and cutting-edge research emerging from our RTOs.”Pierre Chastanet, Head of the Unit for Microelectronics and Photonics, European CommissionEchoing the call for action, Oliver Schenk, Member of the European Parliament, urged stronger regional unity. “Europe must act together, act faster, and act with much bigger ambition,” Schenk said, reinforcing the need for cross-border commitment to strengthen the continent’s semiconductor position.Oliver Schenk, Member of the European Parliament, European ParliamentHighlighting Europe’s most critical technology gap, Luc Van den hove, President and CEO of imec, unveiled plans for a new advanced fab backed by €2.5 billion in investment from the EU, the Flemish government, and ASML. Van den hove urged Europe to commit wholeheartedly to advanced technologies: “We must be more ambitious, and focus on disruptive breakthroughs rather than incremental change if we want to ensure a prosperous future.”Luc Van den hove, President CEO, imecAt the CxO Summit, CEA-Leti and ASML signed a memorandum of understanding (MoU) to deepen their collaboration and accelerate innovation in mainstream semiconductor technologies. Building on promising results in hybrid bonding, the partnership will now target 'More-than-Moore' innovations, including heterogeneous integration and novel substrates like SiC and GaN. “We aim to combine ASML’s world-class lithography expertise with CEA-Leti’s system-level innovation,” said Sébastien Dauvé, CEO of CEA-Leti. The collaboration is set to strengthen Europe’s ecosystem by shortening the path from early research to industrial impact.Left: Anne Hidma, Senior Vice President EUR US, ASML; Right: Sébastien Dauvé, CEO, CEA-LetiTurning to Europe’s industrial base, Christian Senger, CEO of Volkswagen Autonomous Mobility, emphasized the need to shift from risk-aversion to opportunity. While the region’s automotive sector faces intense global competition, particularly from China, Senger highlighted that Europe has the potential to lead in new mobility markets. “The market for autonomous roboshuttles for people transport in large cities is forecast to be worth €400 billion in the US and Europe alone,” he said. With American firms like Waymo and Uber leading the robotaxi space, Senger stressed that Europe must “act swiftly to create an environment that supports an autonomous mobility industry here.”Christian Senger, Member of the Board for Fully Autonomous Mobility and Transport CEO of ADMT GmbH, VolkswagenEurope’s Potential to Create Advanced TechnologyOne of these RTOs, CEA-Leti, is responsible for the FAMES pilot line for FD-SOI technology. Sébastien Dauvé, CEO of CEA-Leti, agreed with Pierre Chastenet that the pilot lines show great promise. He said, “FD-SOI is a big trend in semiconductors, because it enables very low power consumption in embedded devices. We think that adoption of the technology will grow in the coming years, and that is good, because most of the technology is produced in Europe.”Sébastien Dauvé, CEO, CEA-LetiEurope is also widely recognized to be the leading global voice on sustainability – a huge issue of concern to the semiconductor industry. Henri Berthe, President of the Semiconductor and Battery Segment at Scheider Electric, told the summit that 500 million tonnes of CO2 emissions per year are attributable to the semiconductor industry – “more than the whole of Mexico emits!” he said. “We need to make fabs more efficient, and that is why Schneider Electric has launched a new playbook with Applied Materials for sustainable energy abundance for the industry.”Henri Berthe, President of the Semiconductor Segment, Schneider ElectricAnother aspect of Europe’s playbook is support for new fabs. The flagship is ESMC, the joint venture between TSMC, NXP Semiconductors, Bosch, and Infineon. Christian Koitzsch, president and managing director of ESMC, reported to the summit that the project to build in Dresden a 12nm FinFET foundry and a 28nm CMOS line, requiring a total investment of €10bn, is on schedule. “We are now developing local supply chains, hosting a series of ESMC Supplier Days which are open not only to German but generally to European suppliers,” said Koitzsch.Christian Koitzsch, President and Managing Director, European Semiconductor Manufacturing Company (ESMC)As Manfred Horstmann, General Manager and Senior Vice President of Global Foundries, pointed out, the building of the ESMC fab means that Dresden is established as the center of a cluster of semiconductor industry companies. “Global Foundries has its Fab 1 and a mask center in Dresden. In fact, one-third of the chips produced throughout the whole of Europe now comes from Dresden.”Manfred Horstmann, General Manager and Senior Vice President, GlobalFoundriesAn example of ambition was given by Terence Gan, Executive Director of the Institute of Microelectronics of Singapore. Gan told the summit how Singapore has used pilot lines to stimulate research and development in new technologies. He said: “We started research into advanced packaging as long ago as 2011. Most people thought we were mad! But today, there is strong demand for our advanced packaging capabilities because of the rise of AI and its need for high-performance computing.”Terence Gan, Executive Director, Institute of MicroelectronicsBreaking Barriers to ProgressDespite momentum, bureaucratic inefficiencies continue to hamper progress. Narjiss Haddaoui, Managing Director of European Economics called for faster decision-making: “In global competition, speed is a decisive factor. To act fast enough, the EU must change its ‘software’ - the processes by which it considers and makes decisions.” Narjiss Haddaoui, Managing Director, European economicsThe stifling character of European bureaucracy is reflected in the region’s approach to building fabs. Herbert Blaschitz, Executive Vice President of Advanced Technology Facilities at Exyte, compared fab construction timelines: 20 months in Taiwan, 34 in Europe, and 38 in the U.S., attributing delays in Europe to paperwork bottlenecks.Herbert Blaschitz, Executive VP of Advanced Technology Facilities, ExyteFabio Gualandris, President for Quality, Manufacturing and Technology at STMicroelectronics raised another concern — 100% of raw materials used in European fabs come from outside the region. Christophe Frey, Vice-President for EU Engagements at Arm France, added that geopolitical tensions are clouding the path forward: “We are a bit lost in the smoke from the big fire in the world’s semiconductor industry.” Fabio Gualandris, President Quality, Manufacturing Technology, STMicroelectronics Christophe Frey, Vice-President of EU Engagements, Arm FrancePlaybooks For Future SuccessSo amid the uncertainty and global tension, what lessons can the industry learn from successful regional examples? Tuomas Korpela, Business Development Senior Manager at Nokia, credited Finland’s strategic procurement and policy tools with enabling a vibrant semiconductor ecosystem: “Finland creates demand for advanced chips using industrial policy tools, alongside strategic procurement in sectors such as defense and aerospace, and connectivity.” Tuomas Korpela, Business Development Senior Manager - Corporate Development Organization, NokiaAt a regional level, Joerg Schulze, Director of the Bavarian Chips Alliance, said that his organization was supported by the Bavarian State Ministry of Economic Affairs, as well as by companies and universities. “We help semiconductor companies to establish themselves and grow here through help with site searches, networking and contacts, funding and support, and talent acquisition,” said Schulze.Joerg Schulze, Spokesperson for the Bavarian Chips Alliance, Director of the Fraunhofer IISB, Bayern Innovativ GmbHCompanies in the European semiconductor supply chain also provided the summit with their insights into the roots of global success. André Grede, Chief Technology Officer of Comet, described how his company’s strategy is not to wait for customers to tell it what they need, but to be “ahead of the curve.” Grede said: “Is staying in sync with the customer enough? Not for us - we are deeply embedded with our customers, and constantly looking to broaden our relevance to them.”André Grede, CTO, CometChristophe Maleville, Chief Technology Officer of Soitec, provided a real-world example of how this is done. He said: “Our engineered substrates using RF-SOI technology reduce the drain on a mobile phone’s battery power, and cut our customers’ board footprint thanks to RF front end integration. As a result, our products are now in 100% of 5G smartphones.”Christophe Maleville, CTO, SoitecAnne Hidma, Senior Vice-President for Europe and the US at ASML, shared the company’s success formula: “The reasons for ASML’s success include customer focus – decide which markets you are going to be in, and which you are not. We are also all-in on innovation. We nurture an ecosystem, which for us includes imec and CEA-Leti, as well as partnerships with academia. And lastly, we have a strong supply base, which is a core strength of Europe.” In a time marked by both uncertainty and opportunity, the example of ASML shows how the European semiconductor supply chain can survive and thrive.Anne Hidma, Senior Vice President EUR US, ASMLEurope’s Path ForwardThe CxO Summit made one thing clear: Europe has world-class innovation, policy momentum, and industrial commitment. What’s needed now is faster execution, deeper collaboration, and the courage to invest in the technologies of tomorrow. As the industry heads toward the $1 trillion milestone, the decisions made today will shape Europe’s place in the semiconductor world for decades to come.On behalf of SEMI, the SEMI Europe team would like to express appreciation to the industry leaders for sharing their visions and readiness to collaborate during the CxO Summit.SEMI ContactLaith Altimime, President SEMI [email protected]

The sensor revolution is shaping the future of connectivity, with innovation in MEMS and imaging technologies paving the way for a smarter and more integrated world.As the world becomes increasingly interconnected, MEMS and imaging sensor technologies are driving transformative changes across industries, shaping the future of connectivity, intelligence, and sustainability. Powered by advances in miniaturization, AI integration, and sustainable design, MEMS and imaging technologies are enabling groundbreaking applications—from autonomous vehicles to wearable health devices—while addressing urgent global challenges like climate change and energy efficiency.

With increasing demand for personalized smart devices, the MEMS and sensor market is undergoing rapid transformation. MEMS sensors are the backbone of smart wearable devices, seamlessly integrating multiple functions to monitor and simplify our day-to-day activities. As applications in healthcare, environmental tracking, and AR/VR expand, the need for ultra-compact, energy-efficient, and intelligent sensors is more critical than ever.In an exclusive conversation with SEMI, Stefan Finkbeiner, CEO of Bosch Sensortec, shared his perspective on the dynamic landscape of MEMS sensor technology. From Bosch’s evolution to a solutions provider with a focus on sustainability and market-driven innovations, Finkbeiner offered a deep dive into how Bosch Sensortec is positioning itself at the forefront of the industry. “We have to think in terms of the end application and determine what the right hardware and software configuration should be in order to provide solutions with the greatest benefit and flexibility.”Further insights into the future of MEMS and sensor technology will be shared by Finkbeiner during his keynote at the SEMI MEMS Imaging Sensors Summit on November 14, 2024, in Munich, Germany. Registration is still open.SEMI: Welcome, Stefan, and thank you for sharing your insights on advanced sensor technologies. Let’s start with a personal question: What motivates and inspires you about working in sensor technology?Finkbeiner: Sensor technology is very diverse and has significant impacts on consumers. We take pride in prioritizing consumers’ needs and benefits. True to the Bosch motto, “Invented for life,” we are committed to making life better, easier and healthier. This is demonstrated in our sensing solutions, which provide valuable data for fitness tracking in smartwatches, enhance the audio experience in hearables, and enable real-time monitoring of air quality to help individuals make informed decisions for a healthier environment. I am fascinated by technology advancements that are enabling the scaling of sensors—and the processing power and intelligence packed into these increasingly compact devices. For instance, our latest acceleration sensors for hearables are the smallest in the world and are nearly invisible at just 1.2 x 0.8 x 0.55 mm³.We leverage innovative wafer level chip scale packaging (WLCSP) to achieve this reduced form factor. These compact, feature-rich, high-performance accelerometers are easier to integrate in the latest generation consumer products where size and functionality are critical requirements.SEMI: How has Bosch Sensortec’s approach evolved over the years and what is the company’s primary focus today? Finkbeiner: We began our success story a few years ago as a hardware supplier, with one of our first applications being the 'Portrait-Landscape' function in smartphones. Over time, we’ve evolved into one of the leading providers of MEMS sensors.Today, we no longer see ourselves purely as a sensor manufacturer, but as a technology solutions provider. Our focus has shifted to think in terms of the end application and determine what the right hardware and software configuration should be to provide solutions with the greatest benefit and flexibility.Achieving this requires significant software and artificial intelligence (AI) development. In essence, we are optimizing software through self-learning models. Hardware remains essential for optimizing power consumption, with most sensors integrating a controller alongside the ASIC to enable seamless software integration.This unique software and hardware configuration unlocks exciting possibilities and broadens our market reach. We see significant growth in head-mounted devices, and we are actively working on related acoustics solutions.SEMI: Looking ahead, what trends do you anticipate will have the most significant impact on the MEMS sensors market?Finkbeiner: We see several trends that will significantly impact the MEMS sensor market. First, there is growing demand for personal health monitoring in consumer and mobile electronics. Wearable devices, in particular, are becoming essential tools for individuals to track their health and fitness status. This trend requires MEMS sensors to become even more accurate, with solutions that include sophisticated software algorithms to ensure reliability, accuracy, and reproducibility. As a result, AI and machine learning (ML) technologies will play a crucial role in enhancing sensor performance.A second important trend is the continued miniaturization of MEMS sensors. To meet customer demands, sensors must integrate more functionality, including edge-processing capabilities. For example, what once may have been a simple accelerometer with a step-counting algorithm is now evolving into a 6-axis Inertial Measurement Unit (IMU) with an integrated microcontroller and advanced AI/ML software. A great example of this is in True Wireless Stereo (TWS) earphones, where the IMU not only tracks steps but also enables complex tasks like dead reckoning and supports 3D audio—all within the tight constraints of a small TWS earbud housing. Low power consumption, as always, is a critical factor for these mobile devices to meet CE (Conformité Européenne) standards.Finally, we believe that smart glasses, augmented reality (AR) and virtual reality (VR) devices are poised to become the “next big thing.” These devices require advanced image projection optics that offer excellent optical quality, low weight, and ease of use to ensure consumer adoption. We believe our MEMS-based LBS (Laser Beam Scanning) solution is ideal for these applications. Additionally, the successful adoption of smart glasses hinges on high-performance MEMS sensors that are compact, accurate, and power-efficient—critical requirements for all-day wearability and functionality.These trends underscore the need for MEMS technology to evolve, integrating greater functionality, precision, and efficiency to meet the demands of next-generation consumer devices.SEMI: What are some of the biggest challenges facing the MEMS sensors industry today, and how can companies overcome them?Finkbeiner: One key challenge is that the smartphone market—arguably the most attractive market for a variety of MEMS and MOEMS sensors—has become more or less saturated. To stay competitive, MEMS companies must innovate existing products while also developing new, differentiated sensors and actuators for next-generation mobile products.SEMI: How is Bosch Sensortec supporting sustainability initiatives?Finkbeiner: We are helping to mitigate climate change with our low carbon footprint solutions.Up to 20% of annual global carbon emissions are caused by forest fires. This is equivalent to carbon dioxide emitted by all the vehicles driven worldwide.

Registration is now open.SEMI: Thank you both for agreeing to share your insights. To start, can you explain the importance of inspection strategies in the context of MEMS manufacturing?Malin: As MEMS devices become increasingly miniaturized and complex, effective inspection strategies are crucial. These strategies not only accelerate the wrap-up of production processes, but also significantly enhance product yield. With tighter tolerances and various materials involved, ensuring the integrity and functionality of each component is more critical than ever. A robust inspection strategy allows us to catch potential defects early, which can save time and costs associated with rework or scrap.Stickler: The evolution of MEMS technology, particularly in AI chips, demands a higher level of inspection sophistication. Traditional methods may fall short in providing the necessary detail and speed, which is why we’re focusing on advanced solutions like our AI-powered 3D X-ray inspection.SEMI: Could you elaborate on how the 3D X-ray technology differs from conventional inspection methods? Stickler: The 3D X-ray technology we utilize acts as a bridge between traditional optical methods and standard 2D X-ray inspection. It offers high-resolution, three-dimensional images without damaging the samples. 3D X-ray technology emphasizes three main benefits: clarity, efficiency, and actionable insights. This means we can obtain detailed images that help us analyze components more effectively, allowing for real-time decision-making.Malin: Moreover, the clarity and detail provided by the 3D X-ray images are critical when it comes to defect analysis in MEMS devices. They allow us to assess mechanical, electrical, and assembly errors in ways that conventional methods simply cannot. This leads to a more reliable production process.SEMI: What specific MEMS defects can be effectively analyzed using this technology?Stickler: There are several types of defects we can analyze. For instance, we can detect mechanical defects such as stiction or fractures, as well as electrical failures like short circuits. The 3D X-ray inspection allows us to visualize these defects in detail. Additionally, we can monitor assembly errors, which are particularly important in complex MEMS devices where misalignments can lead to significant issues.Malin: I’d like to add that early detection of these defects is paramount. The faster we identify issues, the quicker we can implement corrective actions, thereby improving overall yield and reducing production costs.SEMI: You mentioned yield improvement earlier. Can you explain how your technology contributes to that?Malin: Our approach supports process optimization by providing information on product characteristics and, for example, allows us to identify trends early on that may lead to yield issues later. We also aim to accelerate new product introduction in the early phase by rapid feedback, saving time and cost. This is crucial because many defects may not be apparent until later stages of production. With our technology, we can monitor samples in real-time, allowing us to react promptly to emerging challenges.Stickler: By integrating this feedback loop, we can significantly shorten the time to market for new products. This is particularly beneficial in industries where speed and efficiency are essential.SEMI: Can you tell us about Dragonfly 3D World software and its role in this process?Malin: Dragonfly 3D World is a user-friendly software that leverages AI and, specifically, deep learning for image processing.

Ferri shared insights ahead of his keynote presentation at the SEMI MEMS Imaging Sensors Summit on November 14, 2024, in Munich. Registration is open.SEMI: Welcome, Simone, and thank you for sharing your perspective on the dynamics and trends for today’s MEMS and imaging sensors. To start, how would you describe the current market dynamics for these technologies, and what key factors are influencing these dynamics? Ferri: Right now, the MEMS and imaging sensors market is primarily driven by applications such as automotive electronics, consumer medical devices, AI-powered devices, and intelligent wake-up systems.According to Omdia, the MEMS market is projected to reach approximately $11 billion by 2027, with a CAGR of 2.8% from 2022 and 2027. Currently, automotive applications account for 50% of this market, with industrial at 15% and consumer at 35%. Notably, the automotive sector is the fastest growing, with a 5.4% CAGR, driven by the increasing use of inertial measurement units (IMUs) and microphones.In addition, Yole Group estimates that the imaging market, including optical sensing, will grow at a 4.7% CAGR between 2023 and 2029. Although mobile phone applications remain the primary driver of Complementary Metal-Oxide-Semiconductor (CMOS) image sensors (CIS) volumes, other sectors, including consumer electronics, automotive, and security imaging, are also contributing to the growth.Long-term forecasts for smartphone sales have been trending downwards, but mobile phones still remain a major driver of applications, innovation, and overall volume in the imaging market. Notably, the automotive imaging sector is one of the fastest growing markets and is expected to drive additional demand for CIS.Factors that influence the current market include global economic conditions, regulatory changes, geopolitical factors, technological innovations, and the emergence of new applications and use cases.SEMI: Can you elaborate on the growth strategies that STMicroelectronics is adopting to stay competitive in the MEMS and imaging sensors market? Ferri: ST has played a pivotal role in both the MEMS and imaging sensors markets for over two decades with its proprietary silicon technologies. We fully leverage our Integrated Device Manufacturer (IDM) business model, which allows us to support our customers through integrated capabilities for both design and manufacturing.To remain competitive, we are exploring new markets for MEMS sensors, particularly in digital healthcare with biosensors, where wearable devices are expected to exceed 500 million units per year by 2027.We’re focusing on the growing demand for automotive sensors such as accelerometers, Inertial Measurement Units (IMU), and pressure sensors, particularly with the rise of electric vehicles. We are enhancing the integration and synergy between automotive and personal devices. For example, we are combining high-g and low-g accelerometers within a single IMU, enabling accurate fall and crash detection, along with precise orientation and wake-up functionality.AI is another one of our priorities. In today's digitalized world, AI enables real-time, contextual understanding and the ability to make decisions that optimize and reduce the power consumption of the final device. Sensors are no longer merely for data collection. Thanks to AI, sensors can interact with their environment and significantly contribute to innovation and sustainability.We are also prioritizing low power consumption. Our MEMS technology operates in low-power mode with almost negligible energy use, activating only when necessary, without waking up the system to understand its environment or to be reconfigured.In addition, we’ve seen optical sensing continue to grow year over year. Optical sensing now offers features such as 3D capture, low-power and low-footprint computer vision, Near InfraRed (NIR) and even Short Wavelength InfraRed (SWIR).We are accelerating and leveraging our IDM model and broadband semiconductor supplier positioning to propose wider system offerings based on the array of sensors and microprocessors that ST develops. As the world shifts toward widespread use of sensors and data collection, the demand for secure sensing technologies is growing, extending beyond mobile and PC applications to spatial computing and AR/VR environments. For example, if we are talking about recognizing specific persons in an AR environment, we don't want the data related to these persons to be sent to the cloud before a decision is made about whether they are supposed to be there or not, as such information can be intercepted. We want all the data to be managed at sensor level and only a warning of rejection or acceptance to be transferred outside our secure sensor. SEMI: What are some of the latest technological innovations in MEMS and imaging sensors that are shaping the industry? Ferri: In MEMS, we're seeing significant advancements in three key areas:- In-sensor AI is integrating technologies in the sensors such as machine learning core (MLC), adaptive self-configuration (ASC), and intelligent sensor processing units (ISPU).- Open sensors are designed to interface seamlessly with other sensors, allowing third parties to benefit from on-sensor processing innovations, while building an ecosystem to create joint value with customers.- Accurate sensors are providing high-precision data, enabling better decision-making and smoother, more natural user interactions. These sensors also reduce factory calibration time and resources, leading to overall lower energy consumption. Because of their accuracy, onboard MLC, and ASC, the sensors can also reconfigure themselves without interaction with the processor, thus guaranteeing the proper accuracy at lower power consumption, at any time, under any condition.In the imaging sensor market, key trends include:- Higher Pixel performance is leading to improved signal-to-noise ratio (SNR), low light performance, better quantum efficiency (QE) and lower noise performance. Despite post processing, pixel performance remains the key factor as SNR performance must remain high while the pixel shrink roadmap advances.- Embedded Intelligence is providing local processing for local decision making, enhanced security, advanced image sensor processing (ISP) for improved image quality, and fusing sensor functions to deliver a better user-experience.- "Always on" capabilities are supporting mass sensorization and deployment of optical sensing solutions everywhere through specific low-power design techniques, process development, and overall system architecture optimization.SEMI: Looking toward the future, what trends do you anticipate will have the most significant impact on the MEMS and imaging sensors market? Ferri: Some macrotrends for sensors include:Electrification: Certain consumer and industrial applications are now being adopted in the automotive sector, especially with the rise of electric vehicles creating new opportunities for innovation and for new players to enter the market. As example, the predictive maintenance that has been developed for industrial electric motors is ported 1:1 to electric vehicles.AI: Regarding data transmission, distributed architecture will push AI towards edge computing, increasingly supported by advancements in 6G and foldable technologies. Additionally, as AI becomes more integrated, the maintenance and security for AI will require more attention.Smart home, buildings, and cities: As cities grow, the demand for smart homes and buildings rises, requiring more sensors to manage energy, security, and urban infrastructure efficiently. Over 55% of the global population and 70% of the EU population reside in cities. Urban areas generate more than 80% of the world’s GDP, and by 2030, it's anticipated that 68% of the global population will be urban dwellers, pointing to the growing need for smart cities.Aging population and digital health: The integration of biosensors with MEMS technology will be crucial for addressing the needs of an aging population.Overall, the use of image sensors for environmental sensing is steadily increasing. This is a major focus for ST, particularly in 3D sensing. New use cases, such as presence detection, are enhancing security and reducing power consumption due to efficient data processing. Additionally, the average number of cameras in smartphones, automobiles, and even in devices like robots and vacuum cleaners, continues to grow.SEMI: What has STMicroelectronics been working on, and what are your plans for the upcoming years? Ferri: To date, we have shipped over 23 billion MEMS sensors. Still, we remain committed to continuously improving our products and enhancing our MEMS technology in terms of affordability, miniaturization, performance, and novelty. We are striving to set the stage for a future defined by innovation and excellence with:Evolution of our current product portfolio by investing in lower power consumption, lower supply voltage, and additional and more sophisticated in-sensor AI for an effective distributed AI conceptNew sensors for presence detection, like infrared (IR) sensors, and health-focused sensors such as biosensors.MEMS sensors are also becoming increasingly accurate, open towards different ecosystems of technologies, and so intelligent that they can self-configure and reduce power consumption thanks to optimal data processing. These attributes allow us to provide meaningful and sustainable solutions across sectors such as automotive, industrial, infrastructure, and personal electronics, enabling us to improve energy efficiency, reduce waste, and support sustainable practices for a greener planet.For the past 10 years, ST has focused on depth sensing across multiple use cases. Today, ST is the number one in the world for time-of-flight solutions through our ST FlightSense product family. More recently, we launched our global shutter image sensors family, ST BrightSense, to address markets like personal electronics, automotive, industrial, communications equipment, and computers and peripherals.More specifically on the automotive side, we have the portfolio, customers, and customer program awards to lead the driver and occupancy monitoring market. We continue to secure design wins from our growing customer base while we expand our product portfolio and broaden our customer and application footprints.SEMI: What are some of the biggest challenges facing the MEMS and imaging sensors industry today, and how is ST addressing them? Ferri: The MEMS and imaging sensors industry faces several challenges, but with strategic planning and innovative solutions, companies can overcome these obstacles by focusing on the following:Integration: With our biosensors, we are doing more with less space. For example, in a standard accelerometer, we integrate an analog front end for electrocardiogram (ECG) analysis, enhancing functionality without increasing the device footprint.Performance enhancement: Ensuring high performance and reliability in various environmental conditions is crucial, especially in automotive and healthcare applications. To meet these demands, we deploy comprehensive testing protocols to ensure our sensors meet performance and reliability standards.Power efficiency: Reducing power consumption is vital, particularly for battery-operated devices like smartphones and IoT devices. We are developing low-power architectures to address this need.Data security: With the growing use of imaging sensors in surveillance and personal devices, data security and privacy have become paramount. Our solutions include encryption for data transmission and storage, as well as robust access control mechanisms to prevent unauthorized access to sensor data.Additionally, supply chain issues remain a significant challenge today. We believe our strategy and capacity as an IDM, combined with our strong innovation capabilities, give us a competitive edge in supply chain management.SEMI: What are you most looking forward to at the MEMS Imaging Sensors Summit, and what does it mean for the European semiconductor industry? Ferri: I look forward to the Summit as a valuable opportunity to connect with industry peers, share insights, and explore new collaborations. I encourage my peers to attend, as it’s a unique platform to collectively shape the future of our industry and sustain Europe’s leadership in semiconductor innovation.

Silicon carbide (SiC), with its wide band gap and high thermal conductivity, is increasingly favored for semiconductor power applications across several fast-growing industries. Its ability to operate at higher voltages and frequencies enables significant efficiency gains, particularly in e-mobility, where SiC offers key advantages in size, weight, and speed compared to traditional silicon-based power devices.However, as promising as SiC is, the industry still faces critical challenges in scaling to meet growing demand. Key barriers include cost, reliability, and manufacturing capacity, all of which must be addressed for SiC to fully mature.SEMI spoke with Entegris Senior Director - Advanced Technology Engagements, Office of the CTO Mark Puttock, Ph.D., to discuss the challenges of scaling SiC power chip manufacturing from a material supplier’s perspective. Puttock shared insights ahead of his presentation at the Entegris session, Cultivating a Thriving SiC Market: Tackling Key Challenges Across the Value Chain, taking place on November 14, 2024, at SEMICON Europa in Munich, Germany. Don’t miss the opportunity to engage with experts from Entegris and other industry leaders. Registration is now open. SEMI: Global megatrends like environmental crises and AI drive the necessity for SiC power semiconductors. What is the current status? Puttock: The increasing demand for efficient power electronics — fueled by global megatrends such as vehicle electrification, environmental de-carbonization, and the rise of power-hungry AI chips — drives the necessity of wide bandgap semiconductors. SiC offers advantages of weight, size, and speed over traditional silicon (Si) solutions, which are particularly vital in automotive applications 600V and above. However, SiC chip manufacturing has not reached the maturity of silicon-based processing. Greater maturity will help reduce costs, which will accelerate adoption in the market.SEMI: What are the main challenges in scaling SiC?Puttock: Challenges in scaling SiC power chip manufacturing to high volumes are not surprising. That’s because high volume producers have not been operating long enough to resolve early-stage issues. From a material perspective, SiC is more challenging to manage compared to Si. The challenges we identify include:Chemical Mechanical Planarization (CMP): SiC is nearly as hard as diamond and significantly harder than Si, making it challenging to achieve a high removal rate while maintaining both planarity and low defectivity. This step is crucial toward the end of the wafering process and before the epitaxial growth of device layers.Handling: SiC is more brittle than Si, making it more susceptible to damage or breakage.Implantation: SiC is more difficult to implant than Si, requiring higher temperatures and the use of aluminum instead of boron as a P-type implant species. Additionally, it is a significant challenge to achieve a reliable aluminum source with a long and stable lifetime.Thermal Processing for Wafer Growth and Epitaxy Processes: SiC processes run hotter than Si ( 2000° C for wafering, 1500° C for epitaxial growth), demanding resilient chamber parts to achieve good lifetimes.Sustainability: Because SiC is extremely hard, the CMP process requires significant amounts of slurry. Improving slurry recycling and wastewater management continues to be a challenge.On October 29, we will address these issues in our webinar, “Challenges in Scaling SiC Power Chip Manufacturing: A Material Supplier's Perspective” This session will provide valuable insights and considerations for advancing maturity in high-volume SiC power chip manufacturing. SEMI: Can you elaborate on the challenges associated with CMP for SiC wafers? Puttock: SiC wafers are challenging to process, requiring specialized materials and methods compared to traditional silicon. Defects in the SiC wafer crystal during non-optimized CMP processing can propagate into the device epitaxial layers. This leads to yield loss, increased electrical resistance, reduced performance, and wasted power.SiC wafers must be cut, ground, lapped, and polished to create the necessary surface properties before depositing active layers. As the demand for these devices grows, optimizing the CMP process is essential to ensure the desired surface quality and planarity required for device fabrication. For a deeper understanding of these challenges, we recommend downloading our latest white paper, “Solving CMP Challenges in High-Volume SiC Production,” which covers:Achieving maximum smoothness with high removal ratesReducing the total cost of ownership Optimizing CMP slurry and pads for the unique wafer chemistry and topology of SiC wafersSEMI: What do you mean by optimizing slurry for SiC CMP?Puttock: CMP slurry typically consists of abrasive nanoparticle powder dispersed in a chemically reactive solution. The objective is to achieve a smooth, defect-free surface (less than 1 A Ra) with a high removal rate (greater than 7 µm/m).Traditionally, achieving high removal rates and smooth surfaces required two separate slurries. This approach sometimes forced SiC wafer manufacturers to choose a defect-free surface over a faster, more efficient CMP process, depending on their fab capabilities. Today, optimization allows SiC wafer manufacturers to achieve both high polishing capacity and good final surface quality using a single slurry.Additionally, while the slurry is the most critical part of the CMP process, the pad must be compatible with the application. This ensures the desired planarity while also preventing scratches or contamination of the SiC wafer surface. Research shows that optimized thermoplastic polyurethane CMP pads outperform traditional thermoset polyurethane pads. The optimized pads minimize surface damage and enhance removal rates due to their bulk hardness.SEMI: What are the future challenges for SiC devices? Puttock: SiC devices are increasingly favored for their superior energy efficiency and reduced environmental impact. However, the SiC manufacturing process presents challenges due to its high-temperature operations, which consumes significant amounts of energy and shortens the lifespan of chamber components. To address this, improving efficiency in these processes will be crucial in the coming years.Recycling is another important challenge. For example, CMP slurries present an opportunity for water recycling and conservation. At Entegris, we are committed to this issue and are actively collaborating with key industry players to enhance material circularity and prioritize sustainability in our new product development.SEMI: How is Entegris contributing to advancements in SiC technology, and what initiatives or partnerships do you have planned for the near future? Puttock: Entegris is an active member of the SEMI Global Automotive Advisory Council (GAAC) and participates in a working group focused on SiC with key industry leaders such as Volkswagen, BMW, Porsche Consulting, onsemi, Infineon, STMicroelectronics, and others. Our engagement spans the entire semiconductor supply chain, collaborating with integrated device manufacturers and original equipment manufacturers in fabs worldwide. Additionally, we recently announced our latest long-term agreement with onsemi, which underscores our commitment to advancing SiC technology.SEMI: What are your expectations regarding your participation at SEMICON Europa? Puttock: SEMICON Europa is a unique platform to connect with the semiconductor and automotive ecosystems. Last year, we organized a highly successful SiC session in collaboration with SEMI at both SEMICON West and SEMICON Europa, focusing on “Connecting the Automotive Ecosystem Towards More Mature SiC Manufacturing.”This year, we will continue the discussion with industry leaders during our session, “Cultivating a Thriving SiC Market: Tackling Key Challenges Across the Value Chain.” Our goal is to provide insights and propose solutions that will enable SiC power chips to achieve their anticipated role in future technology ecosystems.We will present alongside Porsche Consulting, and the talks will be followed by a panel discussion that will explore the current state and future prospects of SiC technology in power electronics. We invite visitors to join us at the Executive Forum on Thursday, November 14, from 1:40 – 3:00 p.m. and to visit us at Silicon Saxony booth 219 in Hall C1.About Mark PuttockMark Puttock, Ph.D., is the senior director of advanced technology engagements in the office of the CTO at Entegris.
