Singapore

I recently spoke with Chan Pin CHONG, Executive Vice President and General Manager of Products and Solutions at Kulicke Soffa, about how smart manufacturing is driving new production efficiencies in the semiconductor industry. During our conversation, he also provided practical steps for factory operators to follow in evaluating their smart manufacturing needs in order to ensure successful implementation and discussed the potential payoffs. Based in Singapore, Kulicke Soffa is a leading global provider of ball bonding, advanced packaging, wedge bonding, and electronic assembly equipment for the semiconductor, power and automotive industries.Ng: Industry 4.0 and smart manufacturing are critical to the growth of the semiconductor industry. What does the smart manufacturing movement mean to you or Kulicke Soffa?Chong: The future of smart manufacturing is the vision of building a digital connected factory to drive new manufacturing efficiencies by combining physical and cyber technologies. Industry 4.0 integrates discrete systems and harnesses the power of large volumes of data to move towards greater automation.At K S, we define smart manufacturing across the following four key areas embedded in our roadmap for all K S products, from wire bonders and advance placement tools to pick and place machines: Interoperability – This is about machines, devices and sensors connecting to each other. In fact, the very basis of smart manufacturing is that all devices are connected. Information transparency – Through simulation, various artificial intelligence (AI) tools use contextual information to emulate the actual world. Technical assistance – Robots or machines support humans in making decisions or solving problems. Autonomous decision-making – This is our vision that robots or machines can learn from machines to make decisions on their own. Ng: Please elaborate on some of these areas and how they’re the relevant to smart manufacturing. Chong: The need for machines, devices and people to communicate with each other forms the basis of connectivity, the idea of all machines communicating with each other or a host. Connectivity protocols now in place for machine-to-machine connectivity include SEMA, SECS/GEM, SEMI-ELS and IPC-CFX. Machine technology uses various sensing technologies. For example, for a pick and place machine such as SMT platform on K S Hybrid, the algorithm to recognize and align processes is part of the sensor needed in each machine before to can process and add thousands of components to the substrate or panel. In a wire bonder, the ultrasonics or EFO signal can provide some form of sensing technology for a machine to detect process conditions. Importantly, these sensing technologies can be used to collect feedback for process improvements.One example of how K S machines are connected to the host is our use of an intermediate server or host named KNeXt to connects to all assembly equipment in the fab. The equipment can then, in turn, connect to an external secured cloud or K S Global Cloud.Ng: What are the objectives for smart manufacturing?Chong: The ultimate goal is to achieve higher factory productivity or better OEE (Overall Equipment Effectiveness) by improving machine yields, productivity and efficiency. The key is to leverage AI, 5G, the Internet of Things (Iot) and other industry 4.0 technologies to drive automation and process improvements. Ultimately, each factory must meet productivity, yield and cost goals. Smart manufacturing enables factory operators to meet these goals. That is the focus of smart manufacturing.Ng: What is the biggest potential benefit of smart manufacturing?Chong: Smart manufacturing uses data to predict outcomes of a process step or machine operation. Once data is available in the global cloud, analytics can start to build data sets to run statistical modelling and examine factory operation trends. We can also use the data to identify past machine behaviors in order anticipate outcomes, including undesirable ones that we can then prevent.In the SMT example, if we can systematically examine days or weeks of historical performance, we can plot some statistical variations in the process specifically to a pick or placer or a robot and anticipate or avoid problems. However, all sensors must be in place in the bond head or the robot so that we can detect changes or variations in the robot’s movements.Kulicke Soffa smart manufacturing facility Ng: What are some recent factory improvements smart manufacturing has enabled? Chong: Kulicke Soffa has contributed to the hierarchical architecture of the smart factory and key technologies. COVID-19 is driving demand for greater factory connectivity, and K S offers solutions that are key to remote management and full control of smart equipment from a central control and embedding Internet of Things (IoT), big data, cloud computing and sensors in manufacturing. Using these technologies, a small smart factory can be remotely operated and managed.With COVID-19 limiting air travel around the world and access to support engineers, the need has grown for remote machine access to reduce the downtime per machine. Remote factory access enables off-site engineers to remotely identify and diagnose machine problems.Ng: What are barriers to faster adoption of smart factories?Chong: While most smart factories are capable of network connectivity and data collection, a key challenge is the lack of a business model for smart factories and smart equipment. Most factories must justify major capital investments by demonstrating ROI (Return of investments) potential. Capital improvements for every factory usually take several years to implement and are based on a complex business model. Factory connectivity requires substantial investments and years to implement. The same is true of the cloud infrastructure buildouts necessary to generate big data and meaningful analytics. The executive mandate for factory management to install capability usually calls for specific business targets in the planning stage.Another longstanding barrier to entry is the lack of compatibility of existing tools with new factory protocols, raising the question of whether the cost of replacing legacy tools justifies the need for a smart factory. If new factory investment is required for the latest tools to support the production of new products, the ROI will be much easier to justify.Ng: How is AI is important in smart manufacturing?Chong: AI interprets and learn from data to perform tasks and meet specific goals. Good examples of AI implementations include Amazon’s Siri and Alexa voice-command devices and self-driving cars being developed by Google and Tesla.At K S, over the years we’ve implemented AI in our smart wire bonders to reduce human intervention in our ProCu-7, PSP-2, ProCu Loop 2, Pro Bump and overhang processes.Thanks to AI, with senses of signals from the bonder, we can reduce the amount of parameters that an engineer or technician have to do trial and error. With on bonder metrology, PBI, loop height, wire sway features, AI allows us to measure process efficiency and provide feedback.Over several years of AI development, we have leveraged the technology to monitor machines and provide real-time performance feedback in order to provide better closed loop control such as short tail recovery in our bonder process. We can also use the data to predict machine behavior, monitor its health and track maintenance. Ultimately, AI enables fabs to improve manufacturing efficiency, productivity, yields and device quality.Ng: What’s an example of how AI has solved your manufacturing equipment problems?Chong: We’ve used AI to set RPM (real time monitor) limits, identify defective P-parts and monitor various conditions such as wire size and capillaries. These types of cases can arise in any manufacturing environment as humans make process mistakes or use the wrong part for a machine. With AI, we can prevent these problems and reduce the risk of further material lost from the wire bonding process.Ng: What advice do you have for factories looking to implement smart manufacturing systems?Chong: To build a smart factory, start by focusing on a clear set of business objectives and how smart manufacturing will help minimize or eliminate current factory inefficiencies. In other words, start with the end in mind – the problems that needs to be solved and the business goals – and identify the information you need to demonstrate ROI. Do you need to resolve, automate or improve processes or just to be more efficient? Before investing millions or billions of dollars to build a smart factory, identify those clear goals upfront. Then map out the particulars of implementation to avoid major problems around standards, protocols and connectivity.Bee Bee Ng is president of SEMI Southeast Asia.

Teck Khiong, WOI, senior manager of Factory Integration at Infineon Technologies Asia Pacific Pte Ltd, recently shared with me how the Infineon backend plant in Singapore has benefited from its journey to qualify for the lighthouse certification.WOI is driving Infinion smart manufacturing projects with a strong focus in the area of connect and control using IoT (Internet of Things) and analytics technologies. Ng: How did the Infineon backend plant in Singapore distinguish itself to qualify for lighthouse certification? WOI: The Infineon Singapore backend manufacturing plant is proud to be a Lighthouse Certified Smart Manufacturing site as part of the World Economic Forum’s (WEF) Fourth Industrial Revolution platform. Our Industry 4.0 (I4.0) implementation reduces labor costs by 30% and improves capital efficiency by 15%. We drove this successful digital transformation continuously investing in our people development and digital backbone.Of the many initiatives under our I4.0 Smart Factory platform, five were selected for WEF Lighthouse submission and certification. Digital foundation with integrated connectivity and workflow execution We implemented an Internet of Things (IoT) framework to connect machines to manufacturing system more than two years ago. The digitization of our Work-in-Progress (WIP) management systems provides full traceability and gives us better control of the four Ms (Man-Machine-Method-Material). Material handling and process automation We progressively deployed automated solutions starting six years ago using autonomous transport, robotic material management systems and automation of packing processes. This eliminated non-value touches in areas of WIP storage and retrieval. Advanced algorithms enabled WIP scheduling and dispatching As our product mix and volume grew in complexity, our advanced algorithms has enabled us to increase our machine uptime, thus reducing idle and set-up time. Manufacturing control tower Our control tower provides a real-time pulse of the entire manufacturing process, from machine efficiency to quality. The tower also improves data integrity and collaborative information sharing while issuing early-warning alerts that enable exception management and timely decisions. Running a global virtual factory Our Global Production Network deployments allows us to connect and manage a growing contract-manufacturing network in real time, with the same transparency, traceability and control as if the manufacturers are our internal sites.About Teck Khiong, WOITeck Khiong, WOI graduated from Loughborough University in the UK with a Master of Science degree in Computer Integrated Manufacturing (CIM). For more than 20 years he has delivered manufacturing IT solutions to global backend (assembly and test) semiconductor manufacturing, ranging from equipment, factory, process control, material handling automation and manufacturing execution systems (MES).

Making Strides TogetherKnowledge is power – especially when it is shared. This principle formed the foundation for Micron’s Go and See virtual visit of its Singapore manufacturing plant on 26 August 2020 as 27 companies including GLOBALFOUNDRIES, ST Microelectronics, Infineon, TEL, ViTrox , IBM, HP and UTAC joined the first-of-a-kind virtual factory visit. The chip industry powerhouses gathered to see how Micron’s Lighthouse frontend wafer fabrication facility leverages Fourth Industrial Revolution technologies to drive new production and cost efficiencies.They saw clear markers of a transformed organisation and spoke with working-level staff, managers and front-line employees. Company representatives also met virtually with Micron management teams from organisations that led its digital transformation – from pilot programs to integration at scale – to realise significant financial and operational benefits. The mix of technologies they deployed to make it all happen included artificial intelligence (AI), big data analytics and the Industrial Internet-of-Things (IIoT).Micron’s Singapore-based fab facility earned Lighthouse certification earlier this year from the World Economic Forum’s Global Lighthouse Network. The Go and See tour was co-sponsored by SEMI Southeast Asia and McKinsey Company.Transformation is CrucialBy embracing Lighthouse principles, semiconductor sectors and companies can accelerate their digital transformation to boost operational and financial efficiency while helping increase productivity across the electronics supply chain. It will take time for Southeast Asia semiconductor manufacturers to transform to digital operations, though we’re seeing growing interest in Industry 4.0 practices as they begin to understand that the deployment of new technologies and applications will help them better understand real-world benefits of smart manufacturing use cases and solutions. SEMI believes shining the spotlight on companies like Micron can illuminate the way forward for other companies to help drive the industry’s digital transformation. We look forward to seeing companies build on this momentum as they start to leverage leading-edge technologies to improve efficiencies and promote sustainability.Bee Bee Ng is president of SEMI Southeast Asia.

The COVID-19 pandemic has inflicted major impacts on manufacturing operations worldwide including in the semiconductor industry. The virus has left millions of people confined to their homes, resulting in a massive shift to virtual work and online engagement. In Singapore, where AEM is headquartered, our management team took proactive measures to protect our workers by implementing best practices ahead of the Singapore Circuit Breakers.AEM is globally deemed an essential service, requiring us to maintain operations and minimize impact to our customers. Business continuity plans that include work-from-home and safe-distancing guidelines are in place. As of the time of this writing, we are very fortunate that all of our employees are safe and that we’ve seen only minimal impacts to our customer commitments. AEM has confined this impact by spreading operational risks across our facilities in Asia, Europe, the U.S. and divisions in Singapore, Malaysia, China, North America, Central America, Finland, France and Vietnam. All told, these facilities employ more than 550 people (Figure 1).Figure 1 – AEM Global Presence As a global leader, AEM offers application-specific intelligent system-level test and handling solutions for semiconductor and electronics companies that serve the advanced computing, 5G communications and artificial intelligence (AI) markets.Leveraging our decade of experience, the latest AMPS solutions provide asynchronous, modular, massively parallel and smart system-level testing to meet the new test challenges of complex ICs. The modularity and scalability of these systems enables customers to scale their existing engineering device validation solutions into high-volume, massively parallel production solutions that increase faults coverage, reduces time to market, and decreases cost of test and ownership (Figure 2).Figure 2 – AMPS System-Level Test Solution In meeting 5G infrastructure test needs, AEM developed a field-deployable fiber optics tester. Called WideOptix SR4, the system was initially developed in collaboration with a world leader to support the 5G fiber infrastructure deployment in China and has now been adopted for some Ethernet standards testing. With our WideOptix SR4 development, we cultivated Silicon Photonics (SiPh) testing expertise that complements our AMPS system-level test capability. As part of our business continuation and risk diversifications plan, we had also set up factories in Penang (5,200m2) and Suzhou (3,600m2). Penang’s rising influence in the Southeast Asia semiconductor industry has prompted AMM (AEM Malaysia) to expand its scope to include value-added services with a Center of SSD Excellence and Center of Photonic Excellence.ASZ (AEM Suzhou) will continue to focus on the domestic market in China for further expansion and penetration with products ranging from cost-sensitive testers to state-of-the-art test measurement instruments. In Europe, AEM is focused on wafer-level test and cost-effective ATE test solutions. Finland-based AFORE specializes in MEMS and application-specific wafer testing with the ability to add physical stimulus. The company's state-of-the-art instruments enable the testing of devices such as diced IMU’s (Inertia and Motion Units) in continuous rotation on a wafer mounting ring. Our process increased test throughput by 3X compared to the traditional pick-and-place methods (Figure 3).Figure 3 – Wafer-Level Test Throughput Advantage A specialist in application-specific wafer handling, AFORE developed its latest design to support quantum computing in collaboration with its partner BLUE FORS. The company’s probing equipment features a handling solution with temperature tolerances to 2K (-270’C) to support cryogenic testing (Figure 4).Figure 4 – Cryogenic Quantum Computing Probing Solution AFORE also gained critical insights into creating total darkness, enabling us to further explore opportunities for dark matter testing. AFORE is currently in talks with a member of the LUX Photonics Consortium funded by the National Research Foundation (Singapore) to provide a dark body testing environment and handling for its IR detectors.In Europe, our acquisition of Mu-TEST in France helps diversify our product and service offerings while spreading our business continuity risks. Mu-TEST enjoys collective test-development experience of more than 320 man-years thanks to various ATE suppliers including Schlumberger and Credence. To help combat rising costs of traditional ATE, Mu-TEST developed cost-effective solutions using FPGA-based instruments supported by a full suite of test development, debug and production test software with links to EDA and standard interfaces. This provides Mu-TEST an agile platform that can be easily re-configured for different customer needs.This Mu-Test acquisition expands AEM’s system-level testing capability to include Functional Test, allowing BIST, SCAN, JTAG to test structural failures and perform other application-level test that interface directly with the DUT using the EVM (Electronics Validation) boards to increase fault coverage within the same test environment. Mu-TEST has also enabled AEM to form the recent partnership with UTAC to develop a cost-effective CIS test solution that addresses UTAC’s test needs and complements its CIS advanced packaging solutions. Our U.S. headquarters based in Chandler, Arizona has expanded its capabilities to provide application engineering.In summary, AEM has been expanding its global footprint while managing risk and has been fortunate to be positioned to manage the recent COVID-19 excursions. While each geographical location specializes in core technologies, all sites have access to one another’s manufacturing facilities in times of need and a pool of IP available to address new opportunities. We believe this risk diversification positions us well to serve the needs and interests of our customers worldwide.Lo Wee Tick is Director, Business Development, and Stuart Pearce is Senior Director, Field Marketing, at AEM Holdings Ltd.

The world’s most advanced manufacturing factories are leading the way in driving efficiency and sustainability.In advance of its 2020 meeting, the World Economic Forum welcomed Micron into its Global Lighthouse Network, a group of advanced manufacturers “that are showing leadership in applying the technologies of the Fourth Industrial Revolution to drive operational and environmental impact.”For years, Micron has been helping clients integrate artificial intelligence (AI), big data analytics and the industrial internet of things (IIoT) into their factories. And now Micron’s factory is one of the first facilities in Singapore, along with Infineon, to be recognized by the Global Lighthouse Network.In a recent interview with Channel News Asia, Manish Bhatia, executive VP of Global Operations, explained how Micron has been practicing what it preaches: “Our products enable new technology trends such as IoT, 5G, cloud computing and autonomous driving. Applying these technologies in our own manufacturing facilities demonstrates the enormous potential in driving business value. Industrial IoT and artificial intelligence are part of the biggest revolution since the advent of robotic manufacturing productivity 50 years ago.”For Micron, this journey started with the need to “keep pace with the technological advancement of our semiconductor processes,” Manish said. “We wanted to provide higher-capacity, higher-performance, lower-cost and lower-power chips.”This meant embarking on the same journey they guide clients through: “We started by focusing in 2014 on simple statistical analysis to improve our production processes,” Manish said. “Following that, we developed more complex deep learning and AI capabilities to draw insights from our data. Most recently, we introduced IoT sensors — like cameras and acoustic sensors — to gather even more data that allows us to further improve our production processes.”The Singapore factory plays a critical role in developing leading-edge NAND. Micron’s Singapore presence, composed of two wafer-fabrication facilities and one assembly and test facility, serves as the base for worldwide operations. With over 500,000 square feet of cleanroom space, the location is also a designated NAND Center of Excellence, driving the implementation of the company’s leading-edge 3D NAND production for use in mobile phones, solid-state drives, digital cameras and more. Micron employs approximately 8,000 people in Singapore.The World Economic Forum says the results of the Singapore transformation have been spectacular: Micron’s “semiconductor fabrication facility has integrated big data infrastructure and IIoT to implement artificial intelligence and data science solutions, raising product quality standards and doubling the speed at which new products are ramped.”Below are notable achievements that Micron was recognized for: Automation of production and maintenance produced a 4% tool availability improvement. The IIoT-enabled smart factory led to a 22% scrap and product downgrade reduction. Advanced analytics for process optimization with OEMs reduced time to ramp new products by 50%. Deep learning optical-defect detection created a 2% yield improvement. The integrated deviation management platform reduced time to resolve quality issues by 50%. Micron was a natural choice for the Global Lighthouse Network, an organization whose creation is timely. The World Economic Forum points out that “global production industry is lagging in its adoption of Fourth Industrial Revolution manufacturing technologies, with more than 70% of companies stuck in pilot-phases … [There is] a need for a neutral learning platform to showcase top-use cases, roadmaps and organizational approaches to adopting and scaling technologies from which other companies globally could benefit.”As part of the Global Lighthouse Network, Micron will be able to share knowledge and best practices with peers, support new partnerships and help other manufacturers deploy technology, adopt sustainable practices and transform their workforces. We can all build on this community of like-minded organizations, levering technology to improve efficiencies and promote sustainability.This recognition from the World Economic Forum is a win-win. We look forward to joining the club of lighthouse factories around the world and to helping propel the entire global manufacturing industry into the Fourth Industrial Revolution. At Micron, we are at the forefront of this transformation and welcome the opportunity to serve as a lighthouse.Koen De Backer is responsible for driving Micron’s smart manufacturing initiatives and digital operations including capabilities with IoT, artificial intelligence, advanced analytics, cognitive computing and machine learning to enhance Micron’s business, global operations and product development. Prior to joining Micron, Mr. De Backer led large-scale operations projects for more than a decade to help clients reduce inefficiencies and achieve excellence in manufacturing, procurement, supply chain and support functions.Most recently, De Backer was a partner at McKinsey Company, where he steered the semiconductor consulting practice in Southeast Asia and was one of the firm’s leading experts on applying artificial intelligence and automation techniques across operations and support functions such as finance, human resources and procurement.

Part 1 of 2Read Part 2. While companies navigate the ongoing COVID-19 crisis, corporate leaders should be evaluating a number of key business continuity issues as well as steps they can take to not only react to business disruptions but also reshape their business and recovery plans.We spoke with Dan Steele, Senior Director and the APAC Head of Environmental, Health, Safety, and Security (EHS S) at GLOBALFOUNDRIES (GF) Singapore, via teleconference for insights into the best practices he and his team have implemented from their Business Continuity Plan (BCP) to guide them through the health crisis.SEMI: How did GLOBALFOUNDRIES Singapore first respond when the country reported its first COVID-19 case?Steele: Since the early days of our company, we have had a Business Continuity / Crisis Management (BCCM) team in place that is responsible for business continuity planning for the site. At the beginning of this journey with the coronavirus, we believed in two truths: maintaining the safety and well-being of our employees and consistently communicating precautionary measures the company has taken to protect them and our business. These actions are critical to keeping our employees safe, while keeping the anxiety level low. By informing and updating employees in a timely manner, we ensure that they are well-educated about the crisis as it unfolds and the foreseeable circumstances that could be ahead of us. Once the world was well into the coronavirus outbreak, our CEO declared in a message to all employees that “we entered this pandemic crisis together, and we will exit it together.”We have also established links to pertinent government websites and made them conveniently available to ensure employees have access to the latest available information for their personal lives.SEMI: What actions has GF Singapore taken in response to the crisis so far?Steele: On January 29, our BCCM team activated the first line of defense by initiating temperature checks at all building entrances for every individual including employees, contractors, visitors, and customers who come into our facilities. We asked each to declare their state of health and travel history and issued a temperature card to every employee and resident contractor. They are all required to record their temperature twice daily – once before coming to work and again at midday – and they present the temperature log to security upon their arrival.The following week, our teams split into an A/B work arrangement to ensure continuity of our operations. We proactively pared down our teams to the staff essential for our on-site operations, while enabling the rest to work from home. We also advised our most vulnerable employees with impaired immune systems or who are pregnant to work from home. Concurrently, we moved all meetings of 10 or more people to virtual communications and only allowed meetings with fewer than 10 to be held in rooms with participants sitting at least one meter apart. We informed our customers of our efforts and moved all planned on-site visits to online visits.In line with Singapore’s efforts to curb the spread of COVID-19 within the community, GF restricted site access of people who had recently traveled to countries with sustained community transmission and regularly updated the restriction list. To conduct contact tracing, we created our two degrees of separation list that we used to track employees with families and close associates who were linked to a COVID-19 case. Employees provided the information voluntarily. On our campus, we enforced strict safe distancing measures by limiting access to meeting rooms, marking off-limits tables and removing chairs in the cafeteria, limiting the number of elevator riders to no more than four, and placing boxes or other spacing indicators at smoking zones, bus stops and temperature-taking lines. We also initiated a daily log of employees taking the company buses tagged to the bus number, time, and employee identification numbers in anticipation of the need for contact tracing.Most recently, when the Singapore-Malaysia border closed, we activated the next phase of our BCP that was already in place – housing over 450 Malaysian employees in Singapore hotels.Throughout this crisis, we continuously monitor and evaluate possible impacts to our supply chain to ensure the continuity of our business. This is a standard element of our ongoing business continuity management system.Most importantly, we frequently communicate with our employees and tell them everything the company is doing and why we are doing it. We encouraged employees to monitor their health, stay home if they are unwell, and seek immediate medical treatment if necessary at one of our panel clinics or other medical facilities.SEMI: What are your top concerns amidst this health crisis?Steele: At GF, we are managing through the crisis with an unwavering focus on two guiding principles: the safety and well-being of our worldwide team, their families and communities; and delivering on our commitments to our clients. As the world’s leading specialty foundry, GF has a unique role in the global supply chain. Our semiconductor technology is vital to a range of industries including health care, communications, infrastructure and security. With these priorities in mind, the company undertook unprecedented steps and has adapted to the crisis by dynamically adjusting its protocols, health and safety measures, and business processes to protect its teams while maintaining manufacturing excellence.We are committed to safeguarding the well-being of our employees while supporting and sustaining our on-site operations and protecting customers’ products. A major concern is the impact on our employees. We understand that COVID-19 can be infectious even if an individual is asymptomatic – we are always concerned that temperature screening alone is not sufficient. This is the reason that from day one we have encouraged our employees to monitor their health, follow all government advice for proper hygiene and seek medical attention if unwell as early as possible, and not come to work.Dan Steele has over 25 years of experience in environmental, health and safety, and security operations. He has also held other leadership roles in facilities engineering, quality, reliability and assurance, and risk management.Bee Bee Ng is president of SEMI Southeast Asia.

Flexible hybrid electronics (FHE) is innovation and modern technology at their best, giving rise to lighter, more malleable sensors that better conform to the human body while breeding new applications across a number of markets. For the semiconductor industry, FHE technology is enabling the development of a new generation of chips with the high performance, light weight, scalability, softness and flexibility usually seen in printed electronics. The technology is a boon to chipmakers, giving them novel ways to innovate for the Internet of Things (IoT) market.“The global printed electronics market is expected to garner 14.9% GAGR from 2018 to 2023,” said Stanley Wong, Director of Asia Business Development, Brewer Science, said in his presentation at FLEX Taiwan 2019 in late May. Representatives from industry, government, academia and research institutions gathered at the event in Taipei to explore flexible electronics innovation and growth opportunities.One shining star of FHE innovation is the foldable smartphone. So bright is the future of the bendable devices that not even recent trade tensions between the United States and China have dimmed prospects for the fledgling industry.“While the US-China trade war might slow down shipments of Huawei’s phones, the industry remains bullish on foldable phones,” said Stacy Wu, Principal Analyst at IHS Markit. “When the first generation of flexible AMOLED displays was launched in 2016, the rolling radius was 3mm and it could be folded 200,000 times.”For foldable phones, the 200,000 mark was a major milestone – the industry’s consensus standard for foldable phone display reliability. The industry reasoned that phones capable of being folded and unfolded 200,000 times without distorting color or images or the display itself cracking was a safe bet for consumer adoption. Earlier this year, both Samsung and Huawei announced foldable phones using the thin-film-display technology, ushering in the era of mass-market availability of the devices. Steve Chiu, Division Director for Electronics, IC package, Industrial Technology Research Institute (ITRI), believes that breakthroughs in the next generation of flexible AMOLED technology will allow thin films to be folded 100,000 times with a rolling radius up to 30mm and electric resistivity of less than 10 percent. The rolling radius of 30mm, 10 times higher than today’s phones, will give foldables a higher bending radius, while the lower electric resistivity will help maintain the brightness of the AMOLED panel after tens of thousands usages and extend the service life of foldable smartphones.The biggest challenge facing the foldable phone industry remains developing new materials that are flexible yet durable, stressed Francesco Lemmi, Business Development Director, Flexible Display, at DuPont. Today, the prevailing practice is to layer polyimide (PI) and hard coating on the display module. These stacked protective films replace traditional glass panels but present technical challenges related to impact resistance and the durability of the display as it is folded and unfolded over time.Smart clothing market is another hot market, with 33 percent global growth annually and revenue expected to reach US$ 3.26 billion in 2026. Yet for all the promise of smart clothing, reliability and accuracy remain a big challenge chiefly due to a lack of industry standards. Another gap is the unanswered question of whether consumers will embrace light and energy-efficient products.FLEX Taiwan 2019 speaker Satoshi Maeda of Toyobo is confident they will, pointing out that in the future consumers will enjoy a wide selection of comfortable smart clothing products and applications. The industry is still working to better understand how to develop human-machine interfaces, the essential seam between the human body (the outer layer of skin) and electronics, said Dr. Reinhold H. Dauskardt of Stanford University. Still, he sees great promise in an innovative somatosensory communications platform involving human skin. Human-computer interactions have historically been defined by human touch and vision (for example, typing at a computer keyboard and checking our monitor for the accuracy of our inputs). Dauskardt believes that, in the future, electrical impulses from the skin (conductance) will interact with signals from electronic devices to establish a more intimate human-machine interface that could be adapted one day to extend the visual and auditory abilities of humans.David M. Yeung, co-founder and CEO of Lionrock Batteries, pointed to another challenge in wearables: battery size. Today, large and heavy batteries account for 50 percent to 70 percent of the space in wearable devices, making many of the products too cumbersome to wear. Nanofiber lithium-ion batteries now under development can be as small as ultra-thin 2mm with a rolling radius of up to 20mm in radius and support for high electrical currents, significantly lightening their weight and improving comfort.Nardev Ramanathan, Lead Analyst, Digital Health and Wellness at Lux Research, predicts that, of all flexible electronics products, smart watches will win the largest market share and with the fastest rate of adoption. The devices will get a boost when they shrink as flexible batteries are integrated with the bands. The next wave of smart wearables will feature devices for exercise or medical monitoring. Already, FHE materials have led to advances in medical devices. One example is that smaller hearing aids are now possible thanks to flexible electronics and dressings used to promote skin regeneration, reduce wrinkles and remove scars.Gillian Ewers, VP Marketing at PragmatIC, sees fertile ground for FHE applications in IoT solutions. As FHE manufacturing costs drop, she believes IoT technologies will significantly deepen their penetration into a broad range of industries. For example, the number of electronic tags used in convenience stores worldwide will exceed 100 billion in 2025. Thinner than human hair and more durable than traditional wafers, these tags are expected to spawn a host of new business opportunities. FLEX Taiwan attracted more than 270 attendees from more than 30 fields including smart healthcare, e-paper, displays, system integration, automotive electronics, textiles, wearables, and avionics. On the first day of the event, industry, academia and research center representatives from the United States, Japan, China, Singapore and Taiwan gathered to discuss common goals on a range of FHE-related issues and deepen cross-regional cooperation. Like the FHE industry itself, SEMI-FlexTech remains focused on the future by strengthening cross-border cooperation to help manufacturers find killer applications and test profit-making models. For Taiwanese companies, the event will continue to provide insights on market trends, equipment, materials, advanced manufacturing technologies, product applications and new business opportunities, helping the organizations hone their competitive edge in the global market.Emmy Yi is a marketing specialist at SEMI Taiwan.
