Changdian Technology CEO Zheng Li explains the four major factors in manufacturing automotive chips

SEMICON CHINA 2021 was held in Shanghai. Zheng Li, CEO and director of Changdian Technology, delivered a speech on the theme of "Automotive Semiconductor Chip Packaging and Testing: Challenges and Opportunities". 

Zheng Li pointed out that more than 90% of innovations in the automotive industry are based on chips, and as of now, the total value of automotive semiconductors exceeds US$100 billion. At the same time, the automotive industry has increasingly higher requirements for chip reliability and security.

In recent times, the shortage of automotive semiconductors has affected automobile production. Zheng Li believes that this shortage has triggered two aspects of thinking. First, the development of the automotive industry has higher and higher requirements for chip performance; second, we must fully realize that the engineering management of automotive chips is different from other products such as industrial and consumer products.

According to Zheng Li, the application of finished automotive chips can be divided into ADAS processors and microsystems, in-vehicle infotainment and vehicle safety, in-vehicle sensors and safety control, new energy and drive systems. Among them, the innovation and trend of ADAS chip manufacturing lies in millimeter wave radar, laser radar and ultrasonic (reversing) radar. The four key factors in automotive chip manufacturing are technology, process, quality and awareness.

From the perspective of automotive MCU packaging, Zheng Li pointed out that the global automotive MCU sales in 2021 totaled US$6.5 billion, with QFP and BGA becoming the mainstream packaging methods, with a relevant share of more than 90%. Currently, Changdian Technology has accumulated mass production experience of shipping hundreds of billions of QFPs.

Finally, Zheng Li concluded that in the post-epidemic era, the automotive chip manufacturing supply chain has entered a large-scale reorganization mode and triggered new opportunities; the high integration and performance of automotive chips have promoted innovation in finished product manufacturing technology and promoted the growth of the production and research ecosystem; innovative automotive chip finished product manufacturing focuses on engineering quality control management experience and the formulation of collaborative design processes.
