In a world where technological advancements move at lightning speed, the semiconductor industry is facing unprecedented challenges. The demand for smaller, faster, and more energy-efficient devices is growing, and traditional manufacturing processes are being pushed to their limits. Enter Spin-on Dielectrics (SOD), a breakthrough material technology that offers a cost-effective, scalable solution for micro-gap filling and high-performance dielectric films. As the industry evolves, SOD is expected to play a pivotal role in enabling the next generation of chips that power everything from AI to everyday electronics.To learn more, SEMI Europe and Merck KGaA, Darmstadt, Germany, held a joint webinar that focused on semiconductor device process evolution by SOD. The session featured insights from three technology experts in the company, including Dr. Surésh Rajaraman, Executive Vice President and Head of Thin Film Business Unit, along with Atsuko Yamamoto, R D Manager for Spin-On Dielectric, and Go Nakano, Global Marketing Manager for Dielectric Materials.SEMI: What is SOD, and how does it fit within the broader semiconductor manufacturing process?Rajaraman: SOD, Spin on Dielectrics, is a unique class of materials used to deposit thin layers of dielectric films, which act as insulators or other functional films, on semiconductor devices. The fabrication of a semiconductor chip involves thousands of intricate steps that incorporate conductors, semiconductors, and insulators. SOD is a versatile technology that supports device performance and miniaturization by enabling better gap fill and film uniformity, all while offering attractive cost of ownership.SEMI: Why is there so much focus on SOD materials, and how are they evolving to meet future industry demands?Rajaraman: As semiconductor devices become more complex—such as 3D NAND scaling to more than 300 layers and DRAM incorporating pillar capacitors—there’s a growing need for materials that can address challenges like interconnect delays, power consumption, and heat generation while maintaining optimal performance. Traditional dielectric materials are reaching their limits, making Spin-on Dielectrics (SOD) a critical solution. SOD offers advantages like bottom-up and seam-free gap filling, enabling ultra-thin insulating and other functional layers that enhance electrical and thermal efficiency and support next-generation device scaling.The industry is pushing the boundaries of scaling, with increasing aspect ratios and complex structures in Logic, 3D NAND and DRAM. Modern devices now require deposition in features which are not only incredibly narrow but also increasingly deep due to going into the third dimension. This creates new challenges, such as stress buildup and cracking in conventional SOD materials. To overcome this, we are developing enhanced formulations with improved mechanical stability and polymer backbone engineering. These innovations enhance gap-filling properties and resistance to process-induced stress, ensuring SOD remains a key enabler for advanced semiconductor manufacturing.SEMI: What are the current industry trends driving the adoption of SOD?Nakano: SOD is becoming a key technology because of its excellent gap-filling performance. Unlike gas-phase deposition methods like Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD), SOD is a liquid-phase process. This makes it more efficient for high-aspect-ratio structures. It also helps reduce costs while maintaining high-performance dielectric properties.With increasing demand for high-density memory and logic devices, SOD is crucial for applications like DRAM and NAND flash, which require precise dielectric layer formation. In DRAM, we’re witnessing a shift from planar to vertical transistors, and even to monolithic 3D DRAM. These changes require new materials for gate insulators and electrodes, alongside improvements in aspect ratio gap filling.For NAND memory, manufacturers are increasing the number of memory layers, leading to taller memory stacks and deeper trenches. As lateral scaling progresses, narrower and more complex structures demand high-aspect-ratio trench fills to maintain performance and reliability.Logic devices are also evolving, with transistor structures moving from FinFETs to nanosheets and forksheets. This transition enhances performance, but it also introduces challenges in wiring density and electrical properties. The narrower pitch of wiring requires advanced dielectric solutions, like SOD, to enable reliable, high-performance semiconductor architectures.SEMI: With all these recent innovations, what role does Merck KGaA, Darmstadt, Germany play in supporting these advancements, and what does the company offer its customers? Rajaraman: As the semiconductor industry pushes the boundaries of scaling, doing so requires materials that can support increasingly complex structures. We are the only materials company in the industry to possess the full spectrum of process technologies for gap-filling capabilities, including SOD, ALD, CVD, and Flowable CVD. Our strategic acquisition of Versum Materials has expanded our capabilities with organosilicon precursors. Combined with our SOD expertise, it allows us to reengineer material backbones with more material choices and tailored properties to optimize performance in high-aspect-ratio applications.To support this, we’ve expanded our global R D footprint. We now operate in various application labs, enabling close collaboration with customers for material customization and fine-tuning properties to address specific manufacturing challenges. Last year, we inaugurated a new R D center in Korea as part of our commitment to being near our customers and accelerating time-to-market for next-generation semiconductor solutions. As semiconductor roadmaps become more complex, customization and collaboration also become more critical. The key to innovation lies in working closely with our customers, understanding their challenges, refining materials, and optimizing processes together. By fostering this ongoing partnership, we can accelerate technological advancements and ensure that new solutions align seamlessly with evolving industry demands.SEMI: Can you share some technical insights on SOD?Yamamoto: SOD is a key material used in semiconductor manufacturing to create insulating layers with high precision. One of the essential components in SOD is PHPS (Perhydropolysilazane), a polymer composed of silicon, nitrogen, and hydrogen. This material is applied as a liquid solution and transforms into a high-quality silicon oxide film through a series of thermal processes.PHPS is essential because it enables precise gap filling in extremely small structures, helping to improve device reliability. The process involves spin-coating the polymer onto a wafer, followed by pre-baking to remove solvents. Then, it undergoes high temperature curing in an oxygen and steam atmosphere, forming a dense silicon oxide film. This method ensures uniform coverage and cost efficiency compared to traditional dry film deposition techniques.Our Spinfil® product line has evolved over the past two decades, starting with the Spinfil® 400 series and advancing through the Spinfil® 600 to the widely used Spinfil® 800 series. These improvements have enhanced gap-filling capabilities and film uniformity, making them ideal for high-aspect-ratio trench structures. The critical baking process involves spin coating and pre-baking before wafers undergo batch processing in a high-temperature furnace. Controlled temperature and moisture conditions transform Spinfil® into silicon oxide films, optimizing properties such as refractive index, shrinkage, and etching resistance and ensuring reliability in semiconductor applications.SEMI: What are the latest trends in new polymer development for SOD?Yamamoto: Our research focuses on three key areas: enhancing film quality, developing SOD for high-aspect-ratio trench filling, and advancing low-k SOD for semiconductor processes.To improve film quality, we introduced the Neofil®series, an evolution of the Spinfil® 800 series. This innovation reduces film shrinkage, lowers stress, and enhances wet etching rates, making it ideal for next-generation semiconductor nodes.Our latest Neofil® series for high-aspect-ratio trench filling is targeted for traditional dry processes like CVD and ALD, which can often lead to void formation and require multiple deposition-etch steps. Our latest SOD materials address this by improving polymer elasticity, ensuring uniform filling of deep trenches up to 16 microns without cracks, making them suitable for emerging 3D nanostaircase designs.In low-k SOD development, we’re focusing on siloxane-based polymers, which provide excellent trench-filling capabilities while maintaining strong mechanical and electrical properties. Compared to flowable CVD and ALD, SOD offers a more cost-effective and efficient alternative. With continued advancements, we anticipate SOD will become a key material for future semi-damascene processes, enhancing embedding performance and overall device reliability.SEMI ContactSitong He, Communications Manager Email: [email protected]

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. Our sensors can detect forest fires before they develop into wildfires by measuring various gases such as carbon monoxide and hydrogen. In parallel, we are working with our production partners to reduce our carbon footprint over the coming years, while also replacing or minimizing the use of environmentally hazardous chemicals, such as PFAS.SEMI: What are you most excited about for the MEMS Imaging Sensors Summit, and how do you think it will impact the European semiconductor industry?Finkbeiner: The European semiconductor industry has deep expertise in MEMS and sensor technologies, positioning it to make a significant impact in markets such as consumer health, optical sensing, and AR displays.

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.

Adapted from the Computer History Museum’s “Celebrating the Birthplace of Silicon Valley” invitation. Work that sowed the seeds of the digital, hyper-connected world we know today all started in a squat, unremarkable building in Mountain View, California. Long before the structure’s foundation was laid, Santa Clara County flourished with orchards, not chips. Between the 1880s and 1940s, eight million fruit trees carpeted Silicon Valley. By 1939, San Jose, with a population of 57,651, was the largest canning and dried-fruit packing center in the world, with 18 canneries, 13 dried-fruit packing houses, and 12 fresh-fruit and vegetable shipping firms*.In 1956, silicon sprouted from new fertile ground.That’s when startup Shockley Semiconductor Laboratory, employing some of the most brilliant young minds in the business, produced Northern California’s first silicon transistor prototypes and formed the technological and cultural bedrock for today’s Silicon Valley.Fed up with William Shockley’s hard-nosed management style, eight Shockley employees – including Gordon Moore, Robert Noyce, Julius Blank, Victor Grinich, Jean Hoerni, Eugene Kleiner, Jay Last, and Sheldon Roberts – resigned in September 1957 and founded Fairchild Semiconductor Corporation. Fairchild was the seedling from which companies valued at over $2 trillion have grown and the source of the integrated circuit “computer chip” that has revolutionized our world.Now, more than 60 years later, the site of Shockley Labs, already an IEEE Historical Milestone, is being formally recognized by the IEEE and the City of Mountain View for its historical significance in a special dedication ceremony on August 15. Thanks to the efforts of many, especially developer Merlone Geier Partners, newly commissioned public sculptures – in the likeness of two early semiconductor devices and a mammoth silicon crystal monument that symbolize the work to come out of the lab – now permanently mark the site, along with various plaques that describe and commemorate the site’s history. The event’s featured speaker is Professor James F. Gibbons, former dean of engineering at Stanford University. Professor Gibbons’ first task at Stanford in 1957 was to work with Shockley and his team to transfer their knowledge of silicon fabrication to Stanford, which could in turn train future engineers for the coming boom in the semiconductor industry. He will share his personal experiences and memories of those early days. Join early semiconductor pioneers, the president of the IEEE, SEMI president and CEO Ajit Manocha and local officials on August 15 to commemorate this legendary Silicon Valley landmark. Guests are invited to enjoy a series of presentations and exhibits and view the stunning sculptures and plaques.The event is free to attend and open to the public. Space is limited so please sign up here to guarantee a seat.Location: 391 San Antonio Road, Palo Alto, California (Phase II of San Antonio Village).

Updated Global GDP ForecastThe World Bank just updated its multiyear forecast for GDP growth both globally and by country (Chart 1).It noted: “Despite recent softening, global economic growth will remain robust at 3.1 percent in 2018 before slowing gradually over the next two years, as advanced-economy growth decelerates and the recovery in major commodity-exporting emerging market and developing economies levels off.“This outlook is subject to considerable downside risks. The possibility of disorderly financial market volatility has increased, and the vulnerability of some emerging market and developing economies to such disruption has risen. Trade protectionist sentiment has also mounted, while policy uncertainty and geopolitical risks remain elevated.”www.worldbank.orgSemiconductor Growth Outlook Strong (Chart 2)The WSTS updated its world semiconductor shipment forecast. This new forecast (endorsed by SIA) projects worldwide semiconductor sales will be a record $463 billion in 2018, a 12.4 percent increase from 2017. WSTS projects year-to-year increases across all regional markets for 2018.This revised semiconductor forecast coupled with very robust global semiconductor capital equipment sales (Chart 3) paint a positive outlook for 2018.www.semiconductors.orgwww.semi.orgVery Strong End Market Growth in First Quarter (Chart 4)Based upon the combined 1Q’18 financial reports of 213 large, global OEMs, electronic equipment sales (consolidated into U.S. dollars) increased globally an estimated (and very robust) 10.6 percent in 1Q’18 vs. 1Q’17. While this world growth result is very heartening it was significantly inflated by exchange rate effects as stronger non-dollar currencies were converted into weaker dollars. Looking at world electronic equipment sales consolidated into both dollars and euros, 1Q’18 growth rates are MUCH different (Chart 5). 1Q’18 vs.1Q’17 electronic equipment sales grew 10.6 percent in dollars but declined 4.3 percent in euros! Certainly the first quarter was strong globally but the currency chosen for analysis can have a BIG effect.U.S. Supply Chain Expansion ContinuesLooking at the U.S. market (in dollars - therefore not distorted by exchange rates) domestic electronic equipment orders rose 6.7 percent in February-April 2018 versus the same three-month period in 2017. The U.S. electronic industry is doing reasonably well at present.www.census.gov/manufacturing/m3/Expect the recent exchange rate based amplification of dollar denominated global growth to taper off quickly.Keep a careful watch on the geopolitical situation.Walt Custer of Custer Consulting Group is an analyst focused on the global electronics [email protected]
