At the recently concluded ICCAD 2017, a set of impressive data once again showcased the remarkable growth of China’s integrated circuit (IC) design industry. In 2017, the sales revenue of China’s IC design sector is expected to reach 194.598 billion yuan, marking a year-on-year increase of 28.15%! According to the “National Integrated Circuit Industry Development Promotion Outline,†the total sales of China’s IC design industry are projected to reach 350 billion yuan by 2020, already surpassing the initial target of 150 billion yuan. To maintain this rapid growth, China’s IC design sector must continue to develop more advanced technologies and expand into new markets. With China emerging as a global automobile manufacturing hub, the automotive semiconductor market is expected to play a significant role in this growth.
Research firm IC Insights’ latest report on semiconductor industry drivers highlights that the automotive semiconductor market will be the most dynamic chip application area by 2021, outpacing PC, communications, and consumer electronics sectors. In 2017, automotive IC sales volume increased by 22%, and this growth is expected to continue at 16% in 2018. This booming market is of great importance to Fujitsu Semiconductor Co., Ltd., which participated in ICCAD 2017. Automotive IC foundry is one of the company’s key business areas.
Luo Liangfu, Marketing Director of Triple Fujitsu, shared insights during the “FOUNDRY and Process Technology†special forum at ICCAD 2017. He emphasized that the increasing demands from new energy vehicles and autonomous driving technologies have raised the bar for chip quality. “Chip design capabilities, IP resources, and the stability of the foundry process are now critical factors for automotive-grade chips,†he said. As a leading global foundry company, Triple Fujitsu remains optimistic about China’s automotive design and manufacturing prospects and aims to support the rapid growth of the domestic IC design industry.
The rise of the Internet of Vehicles and autonomous driving has led to a surge in diverse product forms and applications, such as vehicle control systems, smart rearview mirrors, tire pressure monitoring, and ADAS radar. Behind these thriving automotive terminal markets, China’s IC design industry is witnessing an influx of new players entering fields like sensors, low-power MCUs, and wireless connectivity solutions. This trend is reflected in the approximately 1,380 IC design companies operating in China today.
Triple Fujitsu has implemented a 55nm process AEC-Q100 Grade 1/2 standard LSI platform, ensuring high-quality and reliable automotive-grade chips. Luo Liangfu highlighted that functional safety is the top priority in automotive chip design and production. “Ensuring high quality from design to chip flow and maintaining close collaboration with OEMs are extremely critical,†he explained. The company provides customers with a comprehensive automotive-grade LSI development environment, including proven AEC-Q100 Grade 1/2/3 IP, ISO26262 IP, 5V I/O support, precision PDK, automotive DFM, and embedded storage technology.
Triple Fujitsu also offers a rich IP library, including DDC technology, embedded memory (eNVM), and RF series IP, all designed for high efficiency. For example, image processors used in autonomous driving functions (ISP) are widely manufactured by the company. In terms of automotive radar, Triple Fujitsu has developed its own technology and collaborates with the Fujitsu Research Institute to create millimeter-wave MMIC using CMOS technology. The company has also prepared a millimeter-wave Process Design Kit (PDK) for vehicle radar development, positioning itself as a competitive player in this growing market.
Triple Fujitsu currently supports low-power CMOS technology from 40-90nm nodes, offering unique eNVM, RF process options, and millimeter-wave RF technology—key elements for many automotive ICs. The company has strengthened partnerships with Synopsys, Kilopass, and Faraday to fully meet the IP resource needs for IoT chip manufacturing. These collaborations are vital for supporting Chinese companies during the early stages of their design processes.
As a veteran in the industry, Triple Fujitsu has over 30 years of manufacturing experience, with its 55nm process being particularly mature. The company has also achieved ISO26262 certification and provides an automotive LSI design environment, including DFM programs, high-precision PDK, and SPICE models, ensuring both quality and stability in its foundry services.
In addition to meeting the manufacturing needs of various chips, Triple Fujitsu offers vehicle-level chip quality management solutions and BCM (Business Continuity Management) disaster prevention measures. These services form the foundation of the company’s 93%+ wafer process yield. The company employs advanced manufacturing management technologies such as Lot/Wafer Tracking, Preferred Tools, WAT Management, and defect rate zeroing targets. For car-level chips, Triple Fujitsu goes beyond standard AEC-Q100 and operates within a temperature range of -40~125°C, achieving CPK ≧ 1.67 and optimizing SPC regulation.
In terms of BCM disaster prevention, especially earthquake response, Triple Fujitsu was the first in the semiconductor industry to adopt a mixed-isolation structure (AVS), minimizing microseism effects. The company also uses NAS batteries, Li-ion capacitors (LIC), and LNG auxiliary bases to ensure uninterrupted power supply and stable production. Luo Liangfu emphasized that Mie Fujitsu always prioritizes high-quality and reliable production, adhering to ISO14001 for environmental protection and ISO/TS16949 for quality assurance. This ensures continuous and high-quality output of 35,000 pieces/month of 12-inch wafers.
To address the challenges faced by small and medium-sized IC design companies, Triple Fujitsu introduced the “shuttle service†model—a flexible MPW (Multi-Project Wafer) service using 35nm and 40nm CMOS technology. This service allows multiple customers to share masks and wafers, significantly reducing costs and accelerating time-to-market. Luo Liangfu believes that this “shared economy†approach will become a key priority for both Chinese and global customers, helping smaller firms overcome high fabrication costs and improve their competitiveness.
TFT Display
TFT (Thin Film Transistor) is a thin film field effect transistor. The so-called thin film transistor means that each liquid crystal pixel on the Liquid Crystal Display is driven by a thin film transistor integrated behind it. This can Display Screen information at high speed, high brightness, and high contrast. TFT is an active matrix liquid crystal display.
The TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, also known as "true color" (TFT). TFT liquid crystal has a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulses, so each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display, but also can be accurately controlled Display color gradation, so the color of TFT liquid crystal is more real.
In the fierce competition among many flat panel displays, why TFT-LCD can stand out and become the next-generation mainstream display is by no means accidental, it is the inevitable development of human technology and thinking mode. The liquid crystal has avoided the difficult light-emitting problem successively, and the light-emitting display device is decomposed into two parts by using the excellent characteristics of the liquid crystal as a light valve, namely the light source and the control of the light source. As a light source, brilliant results have been achieved in terms of luminous efficiency, full color, and life, and they are still being deepened. Since the invention of LCD, the backlight has been continuously improved, from monochrome to color, from thick to thin, from side fluorescent lamp type to flat fluorescent lamp type. The latest achievements in luminous light sources will provide new backlight sources for LCDs. With the advancement of light source technology, newer and better light sources will appear and be applied to LCDs. The rest is the control of the light source, the technology and process of the semiconductor large-scale integrated circuit are transplanted, the thin film transistor (TFT) production process has been successfully developed, the matrix addressing control of the liquid crystal light valve is realized, and the light of the liquid crystal display is solved. The cooperation of the valve and the controller enables the advantages of the liquid crystal display to be realized.
