For the past several months, U.S. Department of Commerce officials have been developing proposals to amend the foreign direct product rule to require a license for the use of U.S.-origin semiconductor manufacturing equipment or technology in producing semiconductor devices for Huawei and its affiliates. Commerce has also advanced proposals to amend the de minimis rule to expand license requirements for shipments to Huawei and its affiliates of semiconductors produced outside the U.S. and incorporating minimal amounts of non-sensitive U.S. content.The expansion of both rules is among the many Huawei-related actions the administration is pursuing that include a government procurement ban, replacing Huawei equipment in rural U.S. networks, and prohibiting imports of technology and services from unspecified foreign adversary nations. The de minimis proposal was under final interagency review, and the direct product rule next in line for further action, when on February 18 President Trump issued a tweet saying that “The United States cannot, will not, become such a difficult place to deal with in terms of foreign countries buying our product, including for the always used National Security excuse, that our companies will be forced to leave in order to remain competitive.”Speaking to reporters later that day, the president, referring to chipmakers and Huawei, said “I think people were getting carried away with it… Things are put on my desk that have nothing to do with national security.”This week, SEMI President and CEO Ajit Manocha sent President Trump a thank-you letter for his comments and warned that the proposals could severely impact the U.S. and global semiconductor and electronics industries, create confusion and uncertainty in manufacturing supply chains, reduce investment in new capacity, and lead to the design-out of U.S. technology and U.S. components. SEMI also stressed that unilateral controls on U.S.-origin semiconductor devices, equipment, materials and technology could significantly and disproportionately harm U.S. companies, serve as a disincentive for further investments and innovation in the U.S., and impact non-U.S. companies as well. SEMI continues to work with policymakers to build awareness of the damaging and far-reaching effects of these proposals. The 2020 sales forecast for the global semiconductor manufacturing equipment market, excluding the U.S. (since the proposals only directly affect non-U.S. fabs), is approximately $53 billion. With U.S. producers accounting for roughly 40 percent market share, over $21 billion in U.S. equipment sales to non-U.S. fabs could be affected. Non-U.S. companies whose equipment incorporates U.S.-origin components and technology could also be impacted, and every fab worldwide using U.S.-origin manufacturing equipment or technology to produce items destined for Huawei would need to stop their use immediately and file for a license and/or remove U.S.-origin equipment and technology from production lines used for Huawei and its affiliates. The president’s remarks, along with the resignation of two key officials supporting the proposals, have created uncertainty around the next steps. SEMI is holding regular conference calls to keep members up to date and developing strong messages for members to use in their communications with government officials. SEMI Advocacy in Washington remains actively engaged with executive and congressional officials to ensure that U.S. export controls are narrowly tailored to specific national security concerns and applied at the multilateral level with major trading partners.Joe Pasetti is Vice President of Global Public Policy and Advocacy at SEMI.

MEMS technology has changed human interaction with electronic devices. Introduced in the 1990s, the first mass-market MEMS devices were used for inkjet printheads and automotive airbag crash sensors. Today, MEMS are ubiquitous, with billions of the tiny devices adding intelligence and interactivity to smartphones, smart speakers, wearables, automobiles, biomedical devices, remote monitoring and event detection systems, and countless other applications. Integrating MEMS with Flexible Hybrid Electronics (FHE) is an important step in the evolution of this miniaturized intelligent sensing technology, paving the way for its use in new classes of flexible, conformal devices.The integration of the two technologies promises to breed new applications in small form factors but also presents challenges inherent to FHE design and fabrication processes. SEMI’s Nishita Rao caught up with Nathan Pretorius, prototyping and automation engineer, NextFlex, to discuss MEMS-FHE device integration challenges and opportunities ahead of his February 26 presentation, Integrating MEMS Devices in FHE, at FLEX|MEMS Sensors Technical Congress (MSTC) 2020, February 24-27, 2020, at the DoubleTree by Hilton in San Jose, California.Join us at FLEX|MSTC to meet Nathan and other industry influencers advancing innovation in FHE and MEMS sensors. Register now to connect with him at FLEX|MSTC or visit him on LinkedIn.SEMI: Why is integrating MEMS devices into FHE systems important? What new use cases might it enable?Pretorius: The main value proposition of integrating MEMS devices into FHE is that it allows MEMS devices to exist in a different form factor than was possible previously, giving us high-quality MEMS sensors on the flexible and conformable platform of FHE.Ease of application, flexibility, lower cost and rapid iteration on a design are just some of the benefits of FHE devices. And because there are few robust FHE sensors that overlap with MEMS’ capabilities, when you combine the two, you get a lot of compelling uses. That’s why NextFlex is working with agencies and companies to evaluate MEMS’ integration, including using bare MEMS die with microfluidics and promoting new ways of attaching and packaging MEMS die for use with FHE. SEMI: Why is FHE an ideal platform for integrating various types of sensors?Pretorius: MEMS integrated with FHE devices are ideal for rapid design and deployment of data-gathering sensor nodes — which we can iterate for specific applications. A few examples include on-body health monitoring devices for bio-fluids analysis, medical pressure sensors for monitoring blood pressure, and peel-and-stick sensors nodes for infrastructure monitoring. In terms of design and production, FHE devices support rapid prototyping, allowing for instantaneous design-iteration cycles. This speeds design-to-production over traditional rigid PCBs and copper flex because the feedback cycle time between design, manufacturing and testing is shorter, accelerating time to market. What’s exciting about FHE technology is that a variety of sensors or components, including MEMS, can be designed into the base system to easily customize it for a specific application. In addition, our experience shows that when compared to a traditional rigid PCB, an FHE board reduces manufacturing steps and device weight by two-thirds and, perhaps most importantly, converts the device to a thin, conformal shape that makes possible products in new form factors. SEMI: What are the primary challenges to integrating MEMS with FHE? What is NextFlex doing to help device manufacturers address these challenges? Pretorius: There are a few challenges, some of which are device-specific. Most recently, I’ve been focusing on inertial and timing devices, including accelerometers, gyroscopes and resonators. There are a few technical challenges involved in the process of getting the devices from the wafer to an FHE substrate. The wafer processing is very important, especially the dicing and thinning steps. After thinning and dicing, the die is placed onto the FHE substrate. The stresses caused by bonding to the substrate have to be understood and characterized. After placing the die, you then have a calibration step, which is normally performed after the device is packaged. With a MEMS die placed onto directly onto an FHE substrate, calibration then must be done.Finally, the device encapsulation is important, since on an FHE substrate the hard-to-soft material transition is very important to mitigate stresses to rigid component interfaces. We have also been looking at how to work with devices that have damping vents. Flexible encapsulants are inherently more permeable to gases and water vapor than hard encapsulants, so studying the encapsulation of MEMS devices on FHE is another area of interest. NextFlex has been working in a supporting role to evaluate best design practices and best attach and integration methods. In addition to our ongoing collaborative programs, NextFlex is developing the FHE manufacturing ecosystem to include system and component manufacturers and designers, product developers, and materials and equipment providers.SEMI: How do we facilitate closer collaboration between the FHE manufacturing ecosystem and MEMS suppliers such as MEMS device manufacturers, product developers, and materials and equipment providers?Pretorius: It’s important to include manufacturers early in the design process so we can identify challenges up front. That’s why NextFlex spearheads technology road-mapping efforts that include representatives from across the manufacturing ecosystem. We use the roadmaps to prioritize challenges that we can address effectively through collaboration, focusing the industry on solving problems through Project Calls that reveal integration challenges and results from real devices and that tell us how the materials and equipment actually perform with a real device.NextFlex keeps the information flowing, holding quarterly project update webinars to share results. As current devices are optimized for the process in which they will be used, we learn a lot from the project performers who make FHE system demonstrators — and we share that information with the member community. SEMI: Can you point to an example of a successful MEMS-FHE device integration?Pretorius: MEMS-FHE integration is still in the early stages, but we are working on several projects including a DARPA Seedling project for which we have integrated MEMS sensors into FHE systems for testing and evaluation. We plan to continue this work by integrating MEMS and FHE devices using methods that support mass production.SEMI: What would you like FLEX|MSTC attendees to take away from your presentation?Pretorius: We would like to see the FHE community work more closely with MEMS device manufacturers. For example, NextFlex often works with manufacturers to gain access to bare die, which is still a significant hurdle in making devices.The best way to speed things along is to get involved. We encourage FLEX|MSTC attendees to join NextFlex. As a prototyping and automation engineer at NextFlex, Nathan Pretorius explores new print methods for prototyping and automation using novel materials and processes. Pretorius currently focuses on how best to apply software scripting and machine learning to streamline FHE processes. Prior to joining NextFlex, he researched the strengths of roll to roll and screen printing on printed electronics designs, including capacitive touch interfaces, FHE passive component design, and antennas. Nathan holds a Bachelor of Science degree in Graphic Communications from Clemson University.

Critical subsystems technologies for semiconductor applications are highly engineered and specialized pieces of equipment. Only a select group of companies are able to produce these products to the high specifications demanded by the semiconductor industry and in the volume required.

The march of innovation in semiconductor microfabrication technology over the past 60 years has produced electronic devices and information systems that have transformed industries and lives around the world. And while advances in chip technology continue to make it possible to collect, transmit, store and process more data for a rapidly growing universe of applications, the pace of innovation is now facing strong headwinds. Powered by chip innovation, data centers have become massive centers of information processing but, on the downside, enormous consumers of electricity. Today, the power-hungry hubs account for five percent of the world's electricity usage, a proportion that is growing every year, raising important questions about sustainability. Compounding the challenge, the pace of Moore's Law, for decades the engine of electronic device and information system innovation, has slowed. While the research and development of state-of-the-art semiconductor fine processing technology remains robust, developing the advanced manufacturing technology for mass-producing more sophisticated electronics devices is becoming harder, as is ensuring business profitability."It has become difficult for semiconductor technology to continue to evolve as it has in the past," said Akira Minamikawa, Research Director of Technology Research at IHS Markit, who moderated the Semiconductor Executive Forum – View by Top Two in the Era of Digitalization on opening day of SEMICON Japan 2019 at Tokyo Big Sight. Held at the SuperTHEATER, the forum featured Terushi Shimizu, representative director and president at Sony Semiconductor Solutions, and Atsuyoshi Koike, president at Western Digital Japan, two industry powerhouses that could figure heavily in the future of digital technology. SuperTHEATER, the main stage at SEMICON Japan 2019 Image sensors evolve to become eyes of AIImage sensors are becoming eyes of artificial intelligence (AI) and intelligent systems that monitor people and events worldwide, collecting data that one day could help puzzle out growing social challenges such as energy conservation and traffic congestion. With 51 percent market share on the strength of its industry-leading technology, Sony Semiconductor Solutions dominates the image sensor market. Despite last year’s global semiconductor industry slump, the company’s “business continues to enjoy strong growth and we are very busy,” said Shimizu, who attributed the company’s robust performance to the rising importance of the social role of image sensors and the expanding number of applications they support.The success of the company’s image sensors can also be traced to its division of the image sensor market into two application categories: "Imaging" focuses on capturing beautiful image data, while "sensing" aims to collect data that accurately describes the state of a subject and its surroundings."In 2019, sales of imaging products for smartphones grew rapidly,” Shimizu said in his market overview. “This is due to the average annual 15 percent growth rate of multi-camera smartphones, with some phones today featuring seven cameras, and an average annual growth rate of 20 percent in sensor size to produce higher image quality."But Shimizu cautioned that Sony Semiconductor Solutions doesn’t expect the smartphone sensor market to maintain that fast growth rate."The imaging market is expected to grow until 2022, but after that, the sensing market will drive market growth,” he said, adding that the company’s “capital investment plan is based on this scenario."AI will be key in catalyzing growth of the sensor market as integrations of AI processing engines and sensing images grow in sophistication to capture images undetectable by the human eye, Shimizu said. AI will extract insight from captured image data. For its part, Sony will apply its layer stacking technology to sensing products."By stacking an AI processing engine, we want a significant portion of the recognition processing done within the sensor chip," Shimizu said.One sensor the company already offers collects in-depth information for indirect time-of-flight (ITOF) 3D ranging for new user interfaces relying on autonomous or gesture control for robotics. The sensor “was first used in smartphones in 2018 and saw widespread adoption in 2019," Shimizu said.Sony Semiconductor Solutions plans to focus on developing new sensors for integration with their ultrasonic cousins. Aided by optical deflection technology, the sensors will be used for product quality inspections during manufacturing.With the company’s growing strengths in sensor technology, it hopes “to increase sales of sensors from a few percent of the company’s total sales in 2018 to 30 percent in 2025,” Shimizu said, pointing to its goal "to capture 60 percent share of the image sensor market by 2025."Data as one way to spread happinessAt the heart of consumer devices such as smartphones and computers and also cloud servers, NAND flash has made it possible to process vast troves of data anytime, anywhere. In recent years, the technology has enjoyed stronger adoption for use as the storage medium of choice for edge computing, stationed between end devices and the cloud to help streamline data utilization. But the technology isn’t merely about making smarter use of bits and bytes."We would like to promote the technology development that can support the use of data to bring happiness to people around the world," Koike of Western Digital Japan said. The company calls data that contributes to individual happiness and helps solve social issues "data for good" and, like the Sony Semiconductor Solutions bifurcated classification of the image sensor market, categorizes information into “big data” and “fast data.”For example, big data can leverage AI to drive dramatic improvements in the interpretation of test data and, ultimately, the diagnostic accuracy of mammography for breast cancer screening, aiding in early detection to help save lives, Koike said. Fast data can be harnessed to analyze data collected from a manufacturing equipment line in real time to improve production efficiency. The company’s plant in Yokkaichi, Mie Prefecture, which the company operates in cooperation with Japanese memory manufacturer Kioxia, already uses fast data to bolster production.More NAND flash innovation and greater supply capacity are critical to developing "data for good," Koike said. "It is difficult to expand clean rooms at the same pace as data usage grows. In order to continue to advance technology and enhance supply capacity, we need to adopt new ideas for building production lines. We need a smaller equipment footprint, shorter cycle time and higher throughput."Semiconductor market shows signs of recoveryIn their discussion of the short-term outlook for the semiconductor market, Shimizu and Koike pointed to the importance of strengthening the talent pool of Japan’s semiconductor industry as global competition heats up with China’s pursuit of semiconductor independence and the industry pulls out of the 2019 slowdown fueled by weak memory prices. While Sony’s business has been buoyed by strong image sensor demand for smartphones, the devices “did very well, but other applications didn't," Shimizu said. Even the image sensor market stagnated.Despite the 2019 slump, market conditions and capital investments by semiconductor manufacturers have been on the upswing."In the second half of 2019, the Chinese market showed signs of recovery triggered by 5G,” Shimizu said. “In 2020, this movement is going to be in full swing around the world and we will be busier than last year."Koike agreed: "The semiconductor market for data centers will recover with 5G. The hard disk shortage is already an indication of a recovery, a turnaround that will undoubtedly extend to solid state drives (SSDs). In addition, advances in autonomous driving technology will ensure continued growth of the automotive semiconductor industry.”Japan should embrace international competition, not fear China's pursuit of chip independenceIt's no secret that China is investing heavily in its semiconductor development capabilities to move up the microprocessor value chain. Minamikawa posed the question: How should Japanese chip companies navigate the shifting regional balance of power? "It is natural for China to strive to establish domestic procurement of semiconductors that are fundamental technologies for various industries,” Koike said, “I think the efforts of Chinese companies are outstanding in that they are not pursuing short-term results, such as improving yields in the near future, but are making efforts with an eye to achieving results in 10 years. Japan has a variety of options including working with China to create joint ventures and competing head-on. Regardless of which choice we make, however, it is imperative for the survival of domestic companies that Japan maintains its technological competitiveness to remain ahead of China."Shimizu said that Sony’s “Chinese customers are quick to take action and study extremely hard. We often have opportunities to share our roadmap with them and explore innovation opportunities together. Before, they were passive and relied on us for insights into new technologies, but now they are more assertive and I sense that they will start to drive innovation.”Koike added that "although Japanese companies often talk about business globalization, neither Chinese nor American companies say much about it. While global expansion is a major requirement for business, I think Japanese companies need to focus more on the Japanese market overall, not just when they think about the growing competitiveness of Chinese companies." L-R: Akira Minamikawa, Research Director of Technology Research at IHS Markit; Atsuyoshi Koike, president at Western Digital Japan; Terushi Shimizu, representative director and president at Sony Semiconductor Solutions Talent key to bolstering competitiveness of Japan’s semiconductor industryMinamikawa of IHS Markit didn’t mince words in describing the talent shortage in the Japanese semiconductor industry as “grave,” saying that “the workforce challenge is not endemic to the electronics industry as evidence grows that the number of people obtaining doctorates in Japan is falling and the educational level of the Japanese population as a whole is in decline.”Three years ago, Shimizu interviewed professors on Kyushu island for insights into Japan’s talent shortfall. He came away feeling that “Japanese semiconductor companies were not sufficiently communicating the industry's talent and innovation needs to professors. To help professors and students better grasp the appeal and potential of the industry, we have started to send frontline engineers to universities to educate students and instructors about their work and careers. Expecting corporate HR departments to alone solve the talent shortage won’t work.”"In Japan, if you advance to a doctoral course, you will have a hard time getting a job, which is a strange situation,” Koike said. “Companies and universities need to work together more closely to better understand how to attract and hire doctoral graduates."Minamikawa said companies must have strong leaders with clear missions to attract the right talent, but Koike pointed to the drawbacks: "The image of a company with a strong leader seems to be cool, but it also has a downside because engineers stop thinking for themselves and wait for instructions from the top. I believe it is important for company leaders to have ongoing discussions at all organizational levels and lead the way in times of confusion."Shimizu agreed, citing his own company as an example."Thankfully, our company is very busy right now,” he said. “However, some employees are starting to request more time to think about how to improve the quality of their work. To maintain and strengthen our competitiveness and continue business growth, I believe it is important to cultivate an environment that encourages each employee to take more time to think for themselves."Motoaki Ito is the CEO of Enlight, Inc. and a reporter for SEMI.

We are now in the recovery phase of the current business cycle with SEMI equipment already in a growth mode. However significant economic and geopolitical concerns persist.

Augmented reality (AR) tyrannosauruses towered on-screen as I interacted with the creatures in a mix of prehistoric and cutting edge. Or, rather, my AR double was doing the playacting. Minutes later, virtual doppelgangers of a small lineup of chip industry executives cut the ceremonial ribbon. Seemingly sweeping away the winter chill, the opening of SEMICON Japan 2019 dazzled with smart technology and the promise of lives, cities and workplaces transformed, with uber-intelligent applications in full display at Tokyo Big Sight. But what resources does the industry need to harness to drive the next era of innovation? The semiconductor industry’s unwavering passion and young talent are key, said Hiroshi Imano, Chairperson of the SEMICON Japan Initiatives Committee, in his opening keynote. And hardly any region of the world is in a better position to help realize that future than Japan, Imano said. The region supplies one third of the equipment and more than half of all materials to the global semiconductor manufacturing industry.Talent was also top of mind for SEMICON Japan 2019 keynote speaker Makiko Eda, Japan's Chief Representative Officer at the World Economic Forum (WEF). Serving as a platform for public-private partnerships, the organization's mandate is to tackle global issues such as climate change and geopolitical strife in making world more resilient to risk and, by extension, more sustainable.Spanning ecology, economy, technology, society, geopolitics and industry, that mission includes reskilling and upskilling a billion people over the next decade, a high priority for WEF, which hosts a conference every January in Davos, Switzerland. The theme of this month's conference – Stakeholders for a Cohesive and Sustainable World – reflects the vital importance of building the international partnerships and global consensus necessary to achieving WEF's goals.One key to that sustainability will be technology and Arm, a global chip design company, will play a key role, with the company’s chips touching over 70 percent of the world’s population, Arm president Yuzuru Utsumi said in his keynote. Today, Arm is driving toward an ambitious goal: Ship 100 billion chips from 2017 to 2021 – the same number produced over the previous quarter century – by powering advances in mobile computing, server and networking infrastructures, and automotive applications.Arm’s innovation ecosystem of more than 1,000 partners will deliver these chips as they continue to work together to develop differentiated technology. Arm plans to increase investments not only in its primary processor business to accelerate market share gains but in the company’s new IoT business to create new revenue streams. The goal: Deliver long-term sustainable growth, Utsumi said. SEMICON Japan 2019 showcases SMART manufacturing and transportation Billed as a showcase of smart technologies, SEMICON Japan 2019 delivered with an array of eye-grabbing exhibitions in the popular SMART Applications Zone. In the SMART Transportation area, the automatic operation pavilion featured a car equipped with open-source software for autonomous driving. The exhibitor, Tier IV, aims to help lead the early commercialization of self-driving vehicles through the adoption of its software, Autoware, which makes it easier to develop self-driving vehicle prototypes using low-power platforms.Sony Semiconductor Solutions demonstrated a vision sensing processor designed to guide autonomous drones. Using two cameras, the processor measured the changing distance between visitors moving about the exhibit and stationary objects in real time, indicating proximity in hues of red (nearby) and blue (at a distance). Many visitors were wowed, describing the multichromatic display as futuristic.Others rode a simple wooden swing hanging by two ropes, but from dizzying heights thanks to Solidray’s Duo-Sight, a virtual reality (VR) system that projects 3D images stretching from wall to floor for immersive experiences. One visitor thrilled at how riding the swing, suspended only a few feet from the floor, felt like soaring on a flying trapeze. Target applications for the technology include virtual rides at amusement parks and presenting interior design options to homeowners.In the SMART Manufacturing area, one highlight was the demonstration by the National Institute of Advanced Industrial Science and Technology (AIST) of a remote-controlled Minimal Fab System designed for low-volume, high-mix chip production with little staffing. Designed to increase production efficiency, the system allows a circuit designer to manufacture a semiconductor by singlehandedly operating equipment up and down the production line. Controlling nearly 50 pieces of equipment, the Minimal Fab System on display manufactured chips that were verified for functional operation and exhibited afterwards.On the SMART Applications stage, exhibitors DENSO and Toyota Motor Corporation announced a new joint venture to conduct research and advanced development of the next-generation in-vehicle semiconductors critical to electric and autonomous vehicle innovation. The venture, operating as MIRISE Technologies, will combine Toyota’s mobility expertise with DENSO’s in-vehicle component prowess. The goal is to build a rapid, competitive development system by 2030, said Yoshifumi Kato, executive director of the DENSO Research and Development Center, and president and representative director of the venture. On track to begin work this year, MIRISE will span three fields of technology development: power electronics, sensing and SoC (System-on-a-Chip). The name MIRISE combines word the Japanese word "mirai" (future) with "rise."Business Continuity PlanningNatural disasters and other emergencies are an ongoing threat to uninterrupted business operations across the semiconductor manufacturing supply chain and particularly in earthquake-prone Japan. To better prepare for business disruptions and restore normal operations as soon as possible after disaster strikes, more companies are teaming on Business Continuity Planning (BCP).THK's Seismic Isolation Experience Car demonstrated one technology designed to help – a seismic isolation device. The car shakes like an earthquake to give people inside a taste of how a building heaves and sways during a quake with and without the device deployed. Visitors were struck by how much the isolator dampens tremors to prevent or minimize damage. In the BCP seminar, representatives from Sony Semiconductor Manufacturing, THK, DISCO and Team Engineering Consulting shared lessons learned from actual disasters and discussed the critical importance of daily disaster drills. Yukihide Keigo, Executive Engineer in charge of Products and Development at Sony Semiconductor Manufacturing, recounted how the company’s Kumamoto Prefecture plant struggled for 96 days to restore full operations after the facility sustained heavy damage in the 2016 earthquake. Keigo said the plant lacked the structural reinforcements necessary to withstand the impact and fell prey to poor planning and accountability. The Kumamoto plant has since implemented measures – structural and procedural improvements – that more accurately account for seismic risks to ensure full recovery within 56 days. The plant’s new procedures include emergency drills for staff including night-shift workers.Innovation abounds at six SuperTHEATER forumsSEMICON Japan 2019 was held in the West and South Halls of Tokyo Big Sight as organizers of the Tokyo Olympics occupied the East Hall, the exhibition's usual home at the venue, to prepare for the 2020 games. For the first time, the main stage, SuperTHEATER, was set up in the cavernous arena near the main entrance. The SuperTHEATER featured six forums over three days. Semiconductor Executive Forum – View by Top Two in the Era of Digitalization with thought leaders from IHS Markit and Sony Semiconductor Solutions SMART Connectivity Forum – Infinite World Brought by 5G Innovation with experts from Softbank and Nokia Solutions Networks SMART Transportation Forum I – Front-line of Automated Driving featuring speakers from Intel and DENSO SMART Transportation Forum II – Revolution of Sky Transportation, supported by the U.S. Commercial Service in Japan, with presenters from Ministry of Economy, Trade and Industry (METI), Subaru and Bell Helicopter Manufacturing Innovation Summit – Issues and Innovation: What will Drive Growth to 2030 featuring thought leaders from VLSI Research, Applied Materials, KLA, Nikon and Tokyo Electron Mirai Vision Forum – Future Relation of Technology and Body 2.0 with speakers from Leave a Nest, Ory Lab and Autonomous Control Systems Laboratory The Mirai Vision Forum highlighted advanced technologies that could lead to societal improvements. One presenter, Kentaro Yoshifuji, CEO at Ory Lab, recalled how, as a child, he once stayed home from school while recovering from an illness. His imagination in full flight, the youngster imagined having a clone that could attend school and be with his classmates. The experience eventually inspired him to develop OriHime, a robot that gives socially isolated people a way to communicate with friends or colleagues remotely. Originally developed for physically impaired people, OriHime today is used to help the able-bodied. The robot is situated with the companion and the user operates OriHime remotely. A camera and monitor in OriHime’s face provide the visual and audio connection and the user controls the device with a smartphone or tablet or, for those who are paralyzed, through eye movement. One potential application: With OriHime stationed at a business office, working mothers could use OriHime to telecommute to better balance their careers with their parenting responsibilities at home. The robot would be a mother’s go-between, enabling her to communicate directly with colleagues.The next generation of innovators also took the stage as five teams presented innovative business ideas in friendly competition. The top prize in The TECH CAMP Hackathon went to the group that hatched an ingenious plan to develop a jacket that trains users to move their bodies in preprogrammed ways. For example, legendary Japanese professional baseball player Shigeo Nagashima could wear the gear while batting to program the device, then give the jacket to someone who’s never swung a baseball bat. The jacket would help the user replicate Nagashima’s swing. Now comes the real work of any innovator – executing on the vision.And then came two soccer-playing artificial intelligence (AI) robots that squared off and ... Scored! The demonstration by the Toyota National College of Technology started as a research project by Toyota National College students in 2002. The young innovators designed and developed all the robotic hardware and software from scratch. Looking ahead to SEMICON Japan 2020!SEMICON Japan 2019 not only gathered leading Japanese semiconductor materials and manufacturing equipment providers to demonstrate their latest innovations. The premiere regional event also provided insights on key trends critical to the entire electronics manufacturing supply chain. This year’s event drew more than 51,000 visitors and 695 exhibitors from 15 regions filling more than 1,700 booths.SEMICON Japan 2020 returns to East Hall at Tokyo Big Sight in December 2020. I look forward to seeing you there!Jim Hamajima is president of SEMI Japan.

Sapphire is a precious gemstone, consisting of aluminum oxide (α-Al2O3) with occasional traces of other elements such as iron, titanium, chromium, vanadium or magnesium. While sapphire stones found in nature mostly go to jewelry applications, the lab-grown sapphire – produced in a scale of up to several hundred tons per year – is widely used by the electronic industry. Now one can hardly find a branch of technology where this crystal is not used.Sapphires are mainly applied in infrared optical components, high-durability windows, wristwatch crystals, and the very thin electronic wafers used as the insulating substrates of solid-state electronics. High thermal conductivity, low reactivity, and appropriate unit cell size make sapphire an ideal material for a wide range of such electronic substrates for manufacturing of components such as LEDs and CMOS chips.SEMI spoke with Ivan Orlov, CEO of Scientific Visual, after his presentation at SEMI Strategic Materials Conference at SEMICON Europa, 12-15 November, 2019 in Munich, Germany, to learn more about the future of sapphire.SEMI: Why is sapphire an ideal material for a wide range of electronic substrates? Orlov: Sapphire undoubted advantages are its chemical inertness and ability to withstand high temperature, radiation and mechanical loads. In addition, it exhibits low dielectric loss and very good electrical insulation that makes sapphire a good candidate for substrates for LEDs and laser diodes or wafers for epitaxial growth. However, the most important advantage is that sapphire crystal lattice does very well matching semiconductor materials deposited to its surface, in particular nitrides of group III elements. To plainly benefit from these features, the grown sapphire must have as few macro- and micro-defects as possible, as substrate defects are inherited by semiconductors layers grown on the substrate surface. Hence the importance to detect defects in the raw sapphire material. This is the area where our team at Scientific Visual contributes. SEMI: Flaws are usually identified only after costly wafering and polishing steps, because rough surface of raw crystals prevents detection of the defects. What can be done to prevent defects?Orlov: Today, major players are investing in growing larger crystals without mastering in depth the growth process. Let’s face it, the semiconductor substrate industry, which is primarily based in Asia, is using empirical research methods. The raw sapphire boules are still inspected manually, and this qualitative assessment is exploited in two folds. The first step is to further process the boule. Furnace operators then adjust the growing parameters depending on the results of the manual inspection.Due to the lack of visibility into internal crystal defects, the crystal growth and its downstream processing remain an art rather than a science. The primary reasons are the difficulty to measure, locate and quantify precisely the defects in the full crystal volume. Scientific Visual equipment enables defects in raw boules to be fully quantified and categorized. With such objective measurements and knowing the full set of growth parameters, the Process Engineering (PE) team can, with the assistance of deep learning algorithms, considerably improve the growing process. Our quality control tools give Process Engineering team the “eyes” to see complete defect distribution in raw crystals, enabling it to make minor modifications in the growth process to improve yields, reduce costs and shorten the time to market for products.SEMI: What lead to those advancements and what problems did your team set out to solve? Orlov: Breakthroughs in immersion tomography, machine vision and parallel computing drove advancements in automated quality control technology. Previously crystal inspection accuracy was limited by the acuity of the operator’s eye and subjective bias. Light distortion and the diffusion of crystals made it impossible to accurately identify internal defects.Scientific Visual equipment give operators an undistorted 3D view of all defects in a crystal boule or ingot. However, only deep learning technology can correlate a hundred thousand growth data points to identify a final defect pattern.Defect pattern in non-processed item cored from EFG sapphire plate. Well visible is a typical wavy pattern of surface layers and sandwich structure in the volume. Color code marks sapphire defect density: from deep blue (non-defective material) to deep red (highest defectiveness.) SEMI: What challenges are addressed by your approach? Orlov: Increasing the yield of semiconductor substrates like Sapphire, Gallium Nitride and Silicon Carbide is paramount to reducing the price of wafers while increasing their quality. The upstream growth and downstream wafering processes are not deterministic. So far, most of the producers can only determine the quality during the late stages of the process. This condition creates huge constraints for teams in charge of production and processing. Automated Quality Control (QC) at the early stage of the production chain relieves all the unknowns, ultimately reduce the cost of material.SEMI: And what are the main opportunities?Orlov: There are massive opportunities to increase the yield and to ease the full processing chain from growth to the wafering process. Objective Quality Control (OQC) paves the way to industry-wide standards that categorize crystal quality at each step of growth to enable full certification of the defectiveness of the material and facilitate its trade and exchange.SEMI: What’s one of your predictions for the future of new materials?Orlov: The explosion of e-mobility and electric vehicles and the development of other green technologies will drive rising demand for low-defect sapphire, silicon carbide and gallium nitride substrates thanks to the streamlining of the full processing chain. Manual quality control will soon give way to full automation as quality control in sapphire and other raw crystals production is the only missing link in a fully automated semiconductor production chain. I believe that in five years, automated raw crystal inspection will become standard in the industry. Our mission is to empower every crystal grower to achieve this important milestone.Dr. Ivan Orlov obtained a Ph.D. in Crystallography from the Federal University of Technology in Switzerland EPFL and an MSc in Solid-State Physics in Moscow, Russia. Ivan co-founded Scientific Visual in 2010 to answer the challenge of the synthetic crystals industry struggling with high defect yield. Prior to this he worked in a company specialized in diamond optics. He has more than 10 years of experience in R D with focus on optical materials, industrial crystals and non-destructive quality control technologies. Dr. Orlov was a SEMI Task Force member for sapphire standard development in China and collaborates with ISO committee in Switzerland to establish industry-wide sapphire quality standards.Serena Brischetto is senior marketing and communications manager at SEMI Europe.

High-tech industry clusters in the bustling northern Taiwan port city of Hsinchu look set for an upgrade. Long a world-class hub of the semiconductor and optoelectronic technology industries, Hsinchu City is laying out plans to work with SEMI to attract more international companies, generate more jobs, promote Hsinchu’s development and help grow Taiwan’s microelectronics industry. High-tech heavyweights such as TSMC, UMC, MediaTek, Realtek, and AUO are all headquartered in The Windy City. The Industrial Technology Research Institute (ITRI), a leading Taiwan research center and incubator, also calls Hsinchu home, and the city boasts one of the highest concentrations of educational institutions in the region, a roster that includes National Chiao Tung and National Tsing Hua universities. Hsinchu’s thriving relations with these industry, academic and research partners have made it a hotbed of innovation, with numerous large Taiwanese and foreign companies having opened local offices. No less than these partners, the city – like SEMI – is committed to innovation.In a recent visit to the SEMI Taiwan office in Taipei, a Hsinchu City government team led by mayor Lin Chih-Chien, met with Terry Tsao, global SEMI chief marketing officer and president of SEMI Taiwan, to explore collaboration opportunities in areas such as technology subsidies, policy, education, and infrastructure. The meeting built on a relationship between the city and SEMI Taiwan that sprouted after SEMI executives and Hsinchu officials joined ITRI to host the Autonomous Driving System Platform in Open Fields kick-off ceremony – an initiative to accelerate Taiwan’s adoption of smart transportation technologies – at SEMICON Taiwan 2019.At the meeting, Mayor Lin highlighted that Hsinchu has long attracted high-tech companies by cultivating a business-friendly climate through incentives such as subsidies for infrastructure buildouts. He hopes to work with SEMI to promote to members the benefits of setting up local offices in Hsinchu City.With both Hsinchu’s high-tech clusters and SEMI’s global members deeply reliant on skilled workers for sustaining innovation and growth, Tsao and Mayor Lin agreed that inspiring students to pursue an education and careers in science, technology, engineering and mathematics (STEM) is vital to building a high-tech talent pool. One collaboration opportunity SEMI Taiwan is eyeing is to launch Taiwan’s first SEMI High Tech U (HTU) program in Hsinchu to spark the interest of school-age children through STEM educational activities at school camps or art and cultural centers. SEMI’s STEM discovery program offers hands-on activities and experiential learning led by industry volunteers. Since 2002, HTU has reached some 8,000 high-school students in 12 U.S. states and nine countries.Emmy Yi is a marketing specialist at SEMI Taiwan.

The White House and House Speaker Nancy Pelosi announced that the United States has reached final terms on the U.S.-Mexico-Canada free trade agreement (USMCA). The USMCA provides important modifications and updates to the 25-year old North American Free Trade Agreement (NAFTA), and SEMI supports its timely ratification in the U.S. Congress. The USMCA includes significant provisions to protect continued innovation and North American market access across product design and manufacturing supply chains for the electronics industry. The agreement strengthens requirements for the protection and enforcement of intellectual property rights, including trade secrets. The U.S. microelectronics industry will benefit greatly from USMCA’s strong enforcement mechanism for the misappropriation of trade secrets including civil procedures and remedies, criminal penalties, and judicial procedures to prevent disclosure of trade secrets in litigation.The agreement also establishes new rules to enhance and protect digital trade to benefit companies of all sizes and consumers. The USMCA prohibits tariffs, taxes and other barriers to cross-border data flows and minimizes restrictions on where data can be stored and processed. These provisions establish important precedents for data and digital technology in future trade agreements. The USMCA aligns with SEMI’s core principles including open global markets, fair competition and the protection of intellectual property rights. Mexico and Canada are two of the United States’ most important trading partners, and strengthening the three countries’ mutual obligations under USMCA will greatly benefit SEMI members. SEMI welcomes final passage of the USMCA and the critical certainty it will bring to trade rules within North America going forward.Joe Pasetti is Vice President, Global Public Policy Advocacy, at SEMI.

Despite a tough year for critical subsystem suppliers, their overall expenditure on R&D has remained at near record levels– evidence that critical subsystems are indeed critical to the semiconductor manufacturing equipment industry and that high R&D spending on these products is essential.
