Realizing vision of smart transportation with AWS: How Metropia makes Taiwan's MaaS smarter
MaaS (Mobility-as-a-Service), which combines cloud computing, AI, big data, and other technologies, is regarded by national governments and businesses as necessary for realizing a future with smart transportation. Taiwan's MaaS project, which will go online in 2022, integrates various transportation services into a single, convenient platform. The development of this platform was led by Dr. Yi-Chang Chiu, the Founder, and CEO of Metropia. He believes that MaaS needs to aggregate and compute a large amount of information and provide various innovative functions that can quickly respond to user demand. To meet these requirements, Metropia adopted AWS cloud services with the assistance of CKmates.Metropia was founded in the U.S. by a primarily academic team nearly ten years ago when Dr. Chiu was teaching at the University of Arizona. Its core innovation was the creation of a MaaS smart transportation platform that combined mathematical models and modern artificial intelligence (AI) algorithms. They set out to help plan operating models for system integrators, and as such, Metropia has robust technical ability in the field of smart transportation. Since its establishment in 2012, Metropia has been devoted to R&D. In 2015, the first version of Metropia's behavior engine was launched, upon which the company was ranked in the Top 100 Government Technology companies by GovTech in the United States. After a decade, Metropia has expanded to many cities in the United States and was invited by the Taiwanese Ministry of Transportation and Communications to return and assist in planning and constructing a smart transportation platform. Currently, its MaaS platform is the largest such platform in the United States and Taiwan.Dr. Chiu further explained how a MaaS platform works. The platform will integrate various traffic data into a single location. If users want to travel to a certain destination, they are presented with information regarding driving, cycling, public transportation, walking, and other modes of transportation. The platform also considers transfer times and the tradeoffs between time and money. While this concept sounds relatively simple, building a service that can accurately and efficiently fulfill this design is incredibly complex and difficult. For example, Dr. Chiu provided an example of a group of students that wanted to travel with a small budget but plenty of time. The platform would provide them with options that mostly included public transportation, such as the Taiwan Railways or passenger transport, with low fares but longer travel times. Conversely, the options would focus on High-Speed Rail and ride-hailing for business professionals with larger budgets but tighter time requirements. In addition, Metropia's MaaS AI engine can learn from its users' travel histories, recommend suitable modes of transportation, and meet travelers' on-the-road payment needs via the integration of third-party cash services and mobile payment platforms.A powerful MaaS platform that integrates food, accommodation, travel, shopping, and transportation can create diverse business models. For example, lifestyle MaaS operators understand users' travel behavior, meaning their data can be used to recommend more accurate products and greatly increase transaction rates. Tourist-type MaaS operators can offer packaged itineraries that combine transportation plans with meals/accommodations/travel/shopping/etc. By working with overseas travel companies, this platform can greatly expand the foreign tourist market and boost revenue.Integrating these technologies has many more applications, such as understanding consumer travel behavior and instantly pushing discounts to consumers for food, accommodation, travel, shopping, and travel. In its latest report, the market research organization Juniper Research predicted that MaaS platform providers would bring in US$53 billion in revenue by 2027, which shows that the appetite for MaaS will only continue to grow.Dr. Chiu pointed out that a fully functional MaaS platform must integrate a large amount of continually updated traffic data and execute AI algorithms that typically require many computing resources. At the same time, the service has to be able to connect with third-party platforms. This all involves very high requirements for IT system performance. In its early days, Metropia's US office used AWS cloud services to deal with rapidly increasing traffic data volume and the computing needs of MaaS. The Taiwan office was originally set up with an onsite backend system. In order to smoothly connect with the US branch, AWS was later imported with the assistance of CKmates.Metropia chose to use AWS mainly due to its focus on diverse services and scalability. Dr. Chiu pointed out that MaaS uses a huge amount of real-time traffic data that can change rapidly. Therefore, it requires an IT system with sufficient storage and computational resources. Building an independent system that can operate smoothly would require a hefty investment of both time and money. Organizing a professional team to develop various functionalities and upgrades and maintaining the software and hardware is quite burdensome for new startups. It is in these very circumstances that AWS helps tremendously.Since AWS already has its own hardware resources and various functional modules, Metropia only needed to select the appropriate software and hardware according to its current needs, which could be immediately brought online. If the user load changes in the future, the service could be increased or decreased accordingly. This feature helped optimize the IT budget efficiency of Metropia, allowing them to expand their IT system according to demand flexibly. Dr. Chiu mentioned that Metropia frequently used the AWS Auto Scaling expansion plan. This function allowed Metropia to automatically search for relevant resources and set expansion plans within a short period of time. This functionality would take a lot of time for an onsite system to develop. The AWS platform comes completely ready to use. In addition, the stability and information security offered by AWS is virtually unmatched.Dr. Chiu advised how to start using AWS based on his experience introducing it to Metropia. He said that with AWS' many functions, it is inevitable that first-time users may be overwhelmed by the many choices. He suggested that businesses cooperate with vendors with professional experience in this area. Metropia sought out CKmates, a business familiar with AWS with long-term experience coaching enterprises to build IT systems. They assisted Metropia in choosing suitable software and hardware services to maximize ROI.With the assistance of CKmates, Metropia has been able to make good use of the various cloud services provided by AWS. Ever since it has focused its enterprise resources on its core business. For future planning, Dr. Chiu revealed that he would continue using AWS's power to improve Taiwan's MaaS platform and provide a convenient and smart transportation service for the people of Taiwan.If you want to know more about metropia, please click the link. https://www.metropia.com/Metropia's Director of Mobility System Jeff Lin (left), Metropia's Technical Director Sibu Wang (middle) and CKmates' Senior Sales Representative Chun-Cheng Zhao (right)

Investing in talent in the short term and for the long game
The word "shortage" has figured prominently in the semiconductor industry over the past several years. From automotive to industrial, very few businesses found themselves with enough chips to keep up regular production. Alongside the chip shortage, an even larger scarcity looms – a rapidly shrinking workforce.As competition for talent intensifies, the US' government and manufacturers with plans to expand domestic semiconductor production are looking for creative ways to close the employment gap. The solution they are pursuing is to invest in programs now to pave the way to the future. How We Got Here and Where We Are GoingIn the 1960s, the US semiconductor industry was bolstered by fiscal spending and contracts from the Department of Defense (DoD). The DoD enforced open communication, which meant technology was shared by large and small firms alike — enabling rapid, cost-effective innovation. This created a healthy labor market responsible for producing groundbreaking technologies.The industry eventually grew beyond a point where the government could regulate firms' agreements and government contracts dropped dramatically in the 1970s. But technology was swiftly integrating into businesses globally, so there was no lack of profit for the semiconductor enterprise.As policies shifted, "champion" and asset-light design firms took over, favoring larger companies. This created supply bottlenecks for those who lacked funds for substantial orders. As global competition increased, fabless firms, which concentrated on design and sale while outsourcing fabrication to semiconductor foundries, were born, and supply chains became further dedicated to aiding more well-funded companies.Other countries increased their design capabilities, and gradually the US market share of electronic component production dropped to today's level of just 12%.However, expansion plans and changes in US policy are shifting the tides yet again.Some of the biggest developments include:Intel pledging upwards of US$20 billion in fabrication plant construction. Micron announcing plans to finance US$40 billion for memory chips. Samsung, Texas Instruments and GlobalFoundries revealing domestic expansion plans for the next 3-5 years. Qualcomm improving domestic production by upwards of 50% over the next five years.The Stats Stacked Against UsThese developments are exciting, but questions remain about where to find employees. Reports from talent management company Eightfold.ai project that the US semiconductor industry needs between 70,000 - 90,000 new workers by 2025. These numbers only satisfy the most critical workforce needs.These positions require highly skilled and trained talent. The semiconductor electrical engineer workforce has grown three times faster than electrical engineering overall, with 78% more job posts in 2021 compared to 2020.The competition from companies both in the US and abroad makes finding trained individuals daunting. The question is, how does the US bring the global talent closer to home and expand the number of candidates to fit the industry's needs?How to Invest in the Future WorkforceOn August 9th, 2022 President Biden signed the CHIPS and Science Act into law, allocating US$52.7 billion in federal subsidies to domestic chip manufacturing, with funds earmarked to upskill and expand the industry's workforce.Incentives include US$39 billion for manufacturing and US$13.2 billion for R&D and workforce development. Additional allocations are earmarked to create regional innovation and technology hubs, with the goal of increasing private investment and providing country-wide job opportunities.The burden of investing in education also falls on the manufacturers; Intel has joined with universities and community colleges to devote around US$100 million over the next 10 years for science, technology, engineering and mathematics (STEM) programs.If companies hope to encourage students to pursue a career in the industry and work for them over the competition, they should invest in work training programs, and where possible, allocate charitable giving to education programs.Bridging the Talent GapThere are no quick-fix solutions to the semiconductor and manufacturing workforce shortage. It will take a significant investment of time, money and patience to bridge the gap between demand and personnel availability. If the US hopes to reinvigorate the industry, the government and manufacturing companies will need to work together to build a strong future.

Tokyo Electron advanced patterning technologies for EUV lithography address yield and environmental impacts
In 2022, as global inflation has been revised up and with the threats of the conflict in Eastern Europe, the world economy is facing an increasingly challenging and uncertain outlook. Although the market seems to be lessening demand for PCs and consumer electronics, the demand for leading-edge process nodes seems to remain high and continues with high attention because this technology powers high performance computing, 5G/6G, advanced servers, and mobile phones in our pockets.According to the SEMI survey report published on July 12th, 2022, titled "GLOBAL TOTAL SEMICONDUCTOR EQUIPMENT SALES ON TRACK TO RECORD $118 BILLION IN 2022", Global sales of total semiconductor manufacturing equipment are forecast to reach a record US$117.5 billion in 2022, rising 14.7% from the previous industry high of $102.5 billion in 2021, and increase to $120.8 billion in 2023.This interview with Peter Karl Loewenhardt, Senior Vice President at Tokyo Electron Taiwan (TEL in Taiwan), takes a closer look at the new development of leading-edge nodes and how TEL is fulfilling their customers' demand. For example, the industry has moved towards more three-dimensional transistor structures such as the upcoming introduction of Gate-All-Around (GAA) or Nanosheet FET technologies for producing logic chips of the 3nm or 2nm technology generations.Manufacturability and cost become the key to EUV technologyAs extreme ultraviolet (EUV) lithography has moved into the mainstream in advanced semiconductor production, the technologies surrounding it such as spin-on resist and post-exposure development continuously are becoming technically more demanding. The industry is developing advanced exposure technologies for the next process nodes. As one keeps moving down the technology process nodes, EUV patterning becomes more and more critical. The leading foundries have moved EUV lithography into production starting at versions of the 7nm node. Nowadays, the 3nm process node is transitioning into the manufacturing stage. The technology is employing further EUV layers to print smaller features and to reduce masks. In fact, High NA is also on the horizon, and TEL should be able to support this effort well as we have our Coater/Developer equipment installed in imec with their high NA EUV tool.There are many challenges for EUV patterning. For example, resist application and pre-treatments as well as the development after exposure are particularly challenging processes that need to be developed very carefully. The process involves many steps before and after EUV exposure that must be done the right way to solve the technical concerns. Additionally, upstream and downstream technologies like vertical etch, deposition and wet cleaning are essential. Furthermore, there has been a growing need for improvements in the trade-off between photoresist sensitivity, resolution, and line edge roughness. With the exploration of upcoming Metal Oxide Resists (MOR), many performance considerations such as EUV dose, line wiggling/roughness, pattern collapse, bridging defects, etc. present opportunities for further EUV performance improvements. TEL has a very good market position for EUV patterning tools including deposition, Coater/Developer, etch, and cleaning systems and continually invests in improvements in both technology and manufacturability.One must not only deliver leading-edge process technology but also excellent manufacturability to be able to have repeatable performance in every manufacturing process. Additionally, for any technology added to the EUV patterning process, the cost is a major factor that must take significant priority. "With respect to manufacturability, focal areas are how to maximize the output of production, minimize the cycle time, and reduce cost. These are all areas where TEL is focusing," he adds.Meanwhile, there is a growing importance of Advanced Packaging and System Integration. 3nm process node can be integrated with other chips manufactured using different technology nodes, continually advancing on-chip technologies. Heterogeneous integration of different dies together in 3D can help continue the density increase in a more economically feasible way. This approach will make future chips more affordable, which will benefit the chip industry and does make it very exciting. This momentum will continue to next process nodes.Continuing ESG initiatives aimed at continuous corporate value enhancementSemiconductor Fabs consume large amounts of electricity, water, and chemicals. While foundries are getting pushed for improving the performance of EUV lithography in the advanced nodes, there are many photoresist materials and specially designed chemicals to be used for solving stochastics defects as a significant concern to enable yield improvement. As a leading equipment manufacturer, TEL contributes by focusing on leading-edge semiconductor production equipment that can solve difficult technical problems and manufacture devices with a continual focus on reducing the impact on the global environment. This way at TEL we can continue to provide differentiated solutions to customers.In the current technological evolution, one of the notable ESG initiatives is focused on the development of EUV lithography in high-volume manufacturing. There are several areas of focus, particularly in the areas of working with various organic photoresist materials and reducing the doses of EUV exposure. These improvements could be very beneficial, most notably shortening the EUV scanning cycle time and maximizing the EUV production output.EUV scanners are especially expensive. Improved usage of EUV scanners is very valuable for customers. TEL helps customers to increase EUV output performance through technical innovation. Technologies such as ESPERT are enablers for driving down EUV related costs and carbon footprint.Future generations of EUV lithography are expected, and there are several challenges to be overcome. The optimization of the many steps of applying photoresist to wafers (including treatments, etc.) with the optimization of the many steps in post-exposure development focus on improving these challenges, improving yield, etc. Additionally the new technologies could potentially reduce chemical and electricity usage to increase environmental performance through the collaboration of supply chains.With sustainable investments becoming more mainstream, in addition to medium-term environmental goals for 2030, TEL set a long-term environmental goal of reducing greenhouse gas emissions to net zero by 2050 to take the lead in achieving Sustainable Development Goals (SDGs) in industry-wide. For example TEL's Digital Design Square located in Sapporo city in Japan, is a new base for further digital transformation activities enabling various Artificial Intelligence technologies that have demonstrated reduced resource usage in R&D.TEL will continue to strive to fulfilling its sustainability roles and drive SDGs throughout the efforts to match the targets for improving both technical performance and the environmental performance. At SEMICON Taiwan 2022 Forum events, Loewenhardt is an invited speaker to talk about the EUV patterning technologies and performance improvement. The audience could join the event through the registration of SEMICON Taiwan websites at https://www.semicontaiwan.org/zh/node/4671Peter Karl Loewenhardt, Senior Vice President at Tokyo Electron Taiwan

Are tiny microLEDs the next big thing for displays?
KLA is proud to be part of the most significant technological breakthroughs that help create the devices and ideas that transform our current life and shape our future. One of the latest emerging trends is a renewed focus on microLED technology.What is a microLED, and why is the industry focusing on this technology?As the name suggests, a microLED, or µLED, is a light-emitting diode (LED) – roughly 100 times smaller than conventional LEDs. MicroLEDs can be arranged into arrays to make high-resolution displays for applications ranging from smartwatches to very large displays – unlike conventional LEDs, which are suitable only for very large displays like billboards or stadium screens.MicroLED technology was invented in 2000. However, it wasn't until 2012 that a major consumer electronics company demonstrated a 55-inch, high-definition microLED TV. Other companies followed with their own demonstrations in 2018 and 2019 at retail prices of $80,000 for 89-inch models, making the technology out of reach for most consumers. Although microLED can potentially offer significant advantages over LCD or organic light-emitting diode (OLED) screens, technology issues and production costs have prevented widespread commercialization.KLA – which has supported the global display industry for more than 40 years – has during the past decade been helping leaders in microLED technologies to overcome many of the obstacles to mass production and reduced costs."Our proven process and process control products are designed to meet the unique and demanding challenges of the complex microLED production flow to help accelerate wide market adoption," said Chet Lenox, KLA fellow, industry and customer collaboration.While more products, based on slightly larger "miniLEDs" (typically ~50µm-300µm square), have been brought to market successfully in recent years as a way to improve on traditional LED backlighting for LCD displays, screen manufacturers and their supply chain are still committed to developing the more advanced microLED technology. In addition to the key goal of reducing product cost for consumers, companies are investing heavily in microLEDs for use in small products like watches and augmented reality (AR) headsets because they deliver better energy efficiency, consistent pixel quality and other key benefits as shown in the graphics below.The potential market is huge. Shipping for microLED displays is expected to total 5 million and generate $7 billion in revenue by 2025, rising to more than 11 million units shipped in 2027, according to global technology research firm Omdia.A key factor behind the industry's focus on microLEDs is that LCD and OLED displays are produced on large substrates, where all layers are deposited one after the other. The larger the substrate, the more efficient the process – but large single displays can be difficult to handle and ship. MicroLEDs displays, however, can be produced using seamless tiling of small modules into larger displays.Comparison of MicroLEDs, OLED and LCD DisplaysThe schematic cross-section of a typical microLED display (below) shows the simpler and thinner structure of a microLED compared to a thin film transistor liquid crystal display (TFT LCD) or OLED display, with the red/green/blue LED chips and a single electrode encased between the substrate and glass cover. The precise arrangement of the red, green and blue sub-pixels will vary among models and may even be stacked on top of each other.Schematic (not to scale) cross-section through a typical TFT LCD, OLED and microLED pixel illustrating the relative simplicity of a microLED display.MicroLEDs offer viewing performance equivalent to or, for some criteria such as brightness and refresh rate, better than OLED and LCD technologies. They also offer a longer life than OLED, thinner packaging and generally better energy efficiencies.Relative benefits of microLEDs versus TFT LCD versus OLED technologies and where they overlap.The industry must overcome significant manufacturing challenges to achieve acceptable yields and a viable cost point, including:*Baseline yield optimization at each process step*Selecting known good die with fully functioning red/green/blue microLEDs to be transferred*Flawless backplane circuit design and patterning – in-process inspection, testing and potential repair*Mass transferring millions of micro-sized red, green and blue microLEDs in the desired arrangement and precise locations (Solutions to avoid this might include the use of white or blue microLEDs with color conversion, growing uLEDs directly on silicon backplanes or using wafer-bonding of epi layers on the backplane.) *New manufacturing technology adoption, new supply chains and cost of changeKLA Solutions for MicroLED ManufacturingEach of the above would seem to add cost and make LCDs and OLEDs more economical. However, KLA's metrology, inspection, wafer processing and repair solutions are critical to helping microLED manufacturers address these challenges, optimize yields, reduce the need for built-in redundancy and reduce expenditures to help microLED displays become a viable alternative to the established technologies.KLA's comprehensive portfolio of solutions for microLED manufacturing provides a pathway to yield improvement throughout the entire process – from epitaxy wafer to final display. KLA's proven process and process control products are designed to meet the unique and demanding challenges of complex microLED production.Author: Carolyn Short, technical communications manager, EPC Group, KLA

HOLTEK 32-bit MCUs to make serious inroads into the smart wall-mounted and portable EV charging equipment area
The electric vehicle (EV) industry has developed a wide range of multi-wheeled electric vehicles, including self-balancing unicycles, two-wheeled scooters, electric motorcycles and bicycles, three-wheeled tuk-tuks and also four-wheeled new energy vehicles. According to TrendForce data, the total global sales of new energy vehicles in the first quarter of 2022 will reach 2 million units, with pure battery electric vehicles (BEVs) seeing the strongest growth, with sales reaching 1.5 million units. However, the problem of insufficient charging piles and the inconvenient location of charging stations has created what is known as user "range anxiety". Therefore, the demand for smart home charging and portable EV charging equipment in commercial and residential facilities is rapidly increasing. According to Grand View Research, the global electric vehicle charging infrastructure market size was valued at USD 19.26 billion in 2021 and is expected to grow at a compound annual growth rate (CAGR) of 30.6% from 2022 to 2030.Holtek Semiconductor has already released and entered volume production of several generations of 8-bit ASSP MCUs directly aimed at one to three-wheeled electric vehicle chargers. This device range is known as the HT45F5Q-x series, for which more information on these complete charger solutions can be found on the Holtek website. To complement this, Holtek also provides a "Charger Development Workshop" which greatly assists customers to rapidly develop their charger products. When used together with the "Charger Volume Production Tool Fixture", it can significantly reduce the time required for factory calibration, thereby increasing production capacity and reducing costs. For four-wheeled electric vehicle charging equipment, HOLTEK has already released different types of Arm Cortex-M core 32-bit based MCUs. These 32-bit devices, such as HT32F50230, HT32F50241, HT32F6771, meet the needs of portable charging guns, wall-mounted chargers and standalone charging pile applications for various types of AC charging equipment. Holtek's HT32 MCU and its NFC Reader controller, the BC45B4523, have already been successfully used in charging equipment products of well-known EV charging companies both in Europe and the US.There are four main common EV charging modes. According to the IEC 61851 specification, the external charging equipment includes:*Mode 1: here the EV is directly connected to a standard home electrical socket via a charging cable (current ≤ 16A). As such cables have no protection features, many countries have banned or restricted their use in public localities.*Mode 2: here the EV is connected to the household AC power grid (current ≤ 32A) via a charging cable equipped with a control and protection device (IC-CPD). This protection device can detect and monitor ground connections, over-current, over-temperature and other protection conditions. This not only ensures safer charging but also complies with electrical specifications. As for common products on the present day market, these include portable charging guns which offer slow AC charging. Mode 3: here the EV is connected to stationary AC power supply equipment (EVSE) through a charging cable. These offer PWM communication, various types of control and a range of protection functions which can meet public safety requirements.*Mode 3 (current ≤ 250A) charging is compatible with Mode 2 (current ≤ 32A) charging. Here common market products include wall-mounted charging piles which have a power of 7KW~11KW and include both AC fast charging and AC slow charging.*Mode 4: this is an external charging device mode which has a DC output. The DC current directly charges the battery without passing through any on-board charger (OBC). Generally, the power provided by EVSE is much larger than that of OBC, which can greatly reduce the required charging time. It requires a higher-level of communication and more stringent safety features. The charging cable is permanently connected to the power supply equipment. A representative product here would be DC super charging piles, which have a general power capability of around 30KW or more, which puts it into the fast DC charging category.Although DC charging piles have high power capabilities and faster charging features, their installation costs are higher and with the number of installation sites being limited, this will make them more difficult to expand. Contrary to this, AC charging equipment has the advantages of lower cost and easier equipment installation. For this reason, wall mounted and standing charging piles will continue to see an increased presence in households, communities, office building and car parks, etc. As for portable AC chargers, in being able to be conveniently carried and the ability to effectively charge almost anywhere, this greatly resolves the mileage anxiety pain experienced when using electric vehicles.HOLTEK is a professional leading MCU IC design company with highly proficient and experienced technical support teams and a global sales and business service system. Holtek's full series of Arm Cortex-M 32-bit MCUs have already entered volume production and have passed UL/IEC 60730-1 Class B software certification, therefore they can provide relevant and complete self-inspection procedures. All of these combined advantages gives Holtek the drive to make serious inroads into the home smart wall-mounted EV charging pile and lightweight portable EV charger market area.HOLTEK 32-bit MCU electric vehicle charging equipment solution
