3D NAND Flash

Smart technologies have gripped the world’s imagination with their promise to revolutionize the way we live and work. With the semiconductor supply chain central to these advances, SEMI Japan in October hosted 200 members for SEMI Japan Members Day as speakers from three of the world’s top device manufacturers – Denso, Sony and Kioxia – offered their perspectives on the strides the semiconductor industry needs to make in three key areas: automotive, smart manufacturing and 3D flash memory manufacturing technology. Automotive Evolution and Electronics – DensoThe automotive industry is re-inventing itself to innovate across connectivity, autonomy, sharing and electric (CASE) and ensure safe, comfortable and environmentally friendly autonomous driving, said Nobuaki Kawahara, executive fellow and director of the Advanced Research and Innovation Center at Denso. Key focus areas of Denso in CASE innovation are Extraordinary Safety and Everyday Confidence. The company’s goal is to minimize damage to vehicles involved in collisions or one-car accidents by making it easier for drivers to detect and steer clear of objects in their path.To improve automobile safety and security, the company is developing advanced driver-assistance systems (ADAS) and autonomous driving technologies as it promotes the confluence of four areas of technology – HMI (Human Machine Interface), environmental recognition, vehicle control assistance, and information and communications. One use case Denso sees as a significant opportunity is deploying sensors such as millimeter-wave radar, cameras and LiDAR to monitor a vehicle’s surroundings, using GPS and precision mapping to pinpoint its location and determine the best route for safety and distance, and then transmitting that information to a motion-control system.Denso is also out to solve the hard challenges associated with autonomous driving in dynamic road conditions. Kawahara pointed out that road conditions vary and that rules for "driving at certain intervals in a certain lane" vary depending on the time of day. Also, on public roads in Abashiri, Hokkaido, where the company is currently conducting field tests, snowfall makes it difficult to recognize road images and gather sensor information. In Asia, it is also common for motorcycles and automobiles to speed along with very little space between them.Image Sensors to Accelerate Development of Smart Manufacturing – SonyTo fulfill the promise of smart manufacturing, the semiconductor supply chain must continue to invest in sensor and imaging technology innovation, said Shigeo Ohba, deputy senior general manager of the Imaging System Business Division at Sony Semiconductor Solutions. For its part, Sony is developing imaging sensors that help network and automate factories to achieve new production and cost efficiencies. For example, the company plans to design devices to increase equipment uptime through predictive maintenance, reduce defect rates and drive other manufacturing efficiencies. The challenge with today’s factory lines that produce a number of different devices is that they are highly complex to manage and therefore prone to human error, undercutting manufacturing efficiency. In the future, AI-powered machines will leverage data analysis to help streamline operations. Adapting an image sensor with AI to machine vision applications can simplify key processes such as measurement and inspection processes while reducing safety and security costs.Of the vast amount of information on all machines connected to the cloud, only essential details will be processed at the edge since edge data processing offers stronger security and reduces data transfer time. Ohba said image sensors will evolve based on edge AI, adding that "AI will be a paradigm shift for image sensors if it’s economically feasible."3D Flash Memory Manufacturing Technology Challenges – KioxiaIncreasing connectivity in factories for smarter, more efficient operations places huge demands on memory since networked devices typically store duplicate data, said Hideshi Miyajima, head of the Advanced Memory Development Center (AMDC) at Kioxia. To meet demand for higher networking speed and capacity, 2d NAND flash memory is moving to 3D and, in particular, three 3D techniques: multivalued memory, cell partitioning and layer stacking.To increase storage capacity, the third-generation 64-layer BiCS FLASH™ stacks layers to form nearly two trillion holes with a diameter of 100nm and a depth of 5μm on a wafer and places a uniform 2-3nm thin film on the inner wall of each 5-μm hole. For its BiCS FLASH™, Kioxia uses a dry etching technique that forms a straight, elongated through-hole and atomic layer deposition (ALD) technology, which creates a uniform laminate atomic layer on the wafer surface to grow materials uniformly and with high precision on large, complex substrates.In order to meet the cost expectations of high-volume 3D flash memory manufacturers, outlays across fabs must be reduced by better monitoring plasma control, enhancing yield through particle control, speeding film formation, and reducing gas, power and water usage, Miyajima said.SMART Transportation and SMART Manufacturing in the Spotlight at SEMICON JapanPlease join us at SEMICON Japan 2019, December 11-13 at Tokyo Big Sight, for the latest developments and trends in SMART Transportation and Smart Manufacturing.

Device manufacturers continue to invest. Spending in cloud data center (compute, networking and storage), automotive (content per car increases), industrial (on content, factory automation, and positive macro trends), and consumer (gaming) end-markets is particularly strong. We see capital expenditure growth in 2018 and early indications pointing to sustainable spending into 2019. We also expect 14 percent increase (YoY) for fab equipment spending in 2018, up from the February forecast of 9 percent, and expect 9 percent increase in 2019, adjusted from the February forecast of 5 percent. 92 future facilities/lines with various probabilities are scheduled to start production in 2018 or later. Fab investment is just one indicator of how growing demand in areas such as from Artificial Intelligence (AI), cloud/data storage, automotive and Internet of Things (IoT) is driving unprecedented spending in the semiconductor industry.

The growth of China’s semiconductor industry outstripped sector expansion in many other regions in 2017 thanks in part to heavy government investments and supportive state policies. But China’s chip industry also struggled under the weight of overheated investment, inconsistent project quality, insufficient investment in research and development, a poor ability to innovate, and barriers to international cooperation. To overcome these headwinds to growth, China must identify global trends in the development of global semiconductor industry and better understand the forces it needs to mobilize to further expand its own semiconductor sector. AI and 5G fuel global semiconductor industry growthIn 2017, global semiconductor industry revenue reached a seven-year peak, expanding 22 percent to nearly USD 420 billion, and entered a new growth phase with artificial intelligence (AI), 5G and other new technologies leading the surge with greater market segmentation, diversification and decentralization. The emergence of smart automobiles, smart cities, smart medicine, AR/VR and other new markets headed the list of new applications. In the next three to five years, semiconductor industry growth is expected to remain stable, with no marked declines. In 2018, the growth rate is expected to fall to between 5 percent and 8 percent, with the expansion more comprehensive and balanced. The memory market, in particular, will find it hard to match its 2017 blistering growth rate. The market’s expected growth of 10 percent to 20 percent will be chiefly driven by DRAM and 3D NAND Flash. In 2019, NAND growth will continue but DRAM shipments could decline. Emphasis on both innovation and investment key to sustainable growth of Chinese IC Under the China government’s Guidelines to Promote National IC Industry Development, designed to provide key policy guidance and capital support for the development of China’s IC industry, the Chinese semiconductor industry is seeing particularly rapid growth that is expected to be a key contributor to continuing global industry expansion. In IC design, HiSilicon and Unigroup Spreadtrum RDA ranked among the top 10 in the world. In wafer fabrication, Chinese IC manufacturing accounted for 13 percent to 15 percent of global market capacity despite SMIC and Huahong Group lagging international competition in advanced processing. In packaging and testing – China’s strongest segment – JCET, NFME and Huatian Technology also ranked in the global top 10. The Guidelines to Promote National IC Industry Development has fueled a boom in capital investments. However, investments must go well beyond fab construction to add new capacity for China’s semiconductor industry to flourish. A strategy for sustainable, long-term chip industry growth must focus more on technology innovation while continuing heavy capital investments, though it takes time for innovation to lead to higher capacity demand and GPD growth and more jobs. Despite large investments by the 02 Special Project in semiconductor equipment and materials, China trails other regions of the world in advanced technologies. Global spending on semiconductor equipment reached a record-breaking USD 56 billion in 2017, with Korea a major driver. In 2017, Samsung alone invested USD 25 billion in semiconductor equipment, followed by TSMC (USD 10.8 billion), Intel (USD 11.5 billion), Hynix (USD 8.5 billion), Micron (USD 0.5 billion), SMIC (USD 2.3 billion) and YMTC (USD 2 billion). In 2018, Samsung’s equipment spending is expected to drop slightly, to USD 24 billion, while investments by Intel and TSMC will be remain roughly equal. China’s equipment spending will continue to grow in 2018, with SMIC and YMTC maintaining investment levels similar to last year’s and other China semiconductor manufacturers starting to ramp up investments. In 2018, China is expected to surpass Taiwan in equipment spending to claim the number two position after Korea. SIIP China dedicated to international connection and cooperation The huge investments in China’s semiconductor industry need to be supported by robust business strategies, greater international cooperation, deeper expertise in advanced technologies, and more skilled workers. China lags the global industry in all of these areas. The rapid rise of China’s semiconductor industry has raised concerns among many countries over China’s growing influence, with some, most notably the United States, going so far as to implement containment measures. Other regions including Japan, Korea and Taiwan followed suit. The continued growth of China’s semiconductor industry hinges on technological innovation enabled by international cooperation, as well as strong international communication to allay concerns and misunderstandings over the rising prominence of China’s chip sector. China must overcome these obstacles. One partial solution is for China to convince the rest of the world that its need a thriving semiconductor industry if only to meet enormous demand for electronics products within its own borders. As the largest international semiconductor industry association, SEMI enjoys a unique ability to strengthen the connection between China’s semiconductor sector and its international counterparts. SEMI is well-known for its vital support of the traditional semiconductor equipment and materials markets, but SEMI’s work also spans IC design, manufacturing, packaging and testing. What’s more, SEMI has expanded into innovative market vertical applications such as AI, smart manufacturing, smart transportation and smart automotive as it aims to bring together supply chains across these growth areas. For its part, SEMI China remains dedicated to improving communications and cooperation between the Chinese and global semiconductor industries. SEMI China will also continue to encourage deeper collaboration among individual enterprises and government institutions in the interest of industry growth while making full use of SEMI’s international, professional and localization platform to promote the development of China’s semiconductor industry. Last year, we established SEMI Innovation Investment Platform (SIIP) China to help grow China’s pool of skilled workers, promote advanced technology, generate industry capital, and expand China’s semiconductor industry while developing stronger connections with chip sectors in other regions. SIIP China is focused on the following: Promoting sustainable development of the Chinese semiconductor industry Establishing stronger connections to help take advantage of global technology and investment opportunities Providing a platform for open communications between the Chinese and global semiconductor industries Promoting greater coordination between China and its global partners Helping newly enterprises secure funds for expansion Encouraging greater cooperation with foreign semiconductor manufacturers in the interest of openness and mutual benefit will be the best way for China to overcome obstacles to the development of its semiconductor industry. Meanwhile, China will continue to strive to merge into the global semiconductor industry and become a key partner. SEMICON China has witnessed the development of Chinese semiconductor industry SEMICON China marked its 30th anniversary this year.
