Automotive semiconductors in the CASE era
Shinojima is the Executive Officer of MIRISE Technologies Corporation. MIRISE is an automotive semiconductor research company established by Denso and Toyota in 2020. Especially, it is researching power devices for electric vehicles and sensors and SoCs for autonomous driving. He is promoting the whole research project there. Before joining MIRISE, he was General Manager of the Power Electronics Development Department at Toyota Motor Corporation. The division mainly developed power devices for HVs and EVs. He received a bachelor's degree in mechanical engineering from the University of Tokyo in Tokyo, Japan in 1985. In the same year, he joined Toyota Motor Corporation and designed control ECUs and digital ICs for vehicle.
CASE (Connected, Autonomous, Sharing & Service, Electric) is a keyword of future mobility society. In the CASE era, semiconductors play an important role. Technology development of the semiconductor required for C, A, S and E respectively advances. Semiconductor for large-scale data processing technology and communication technology necessary for the digital society can utilize the result of other industry (Mobile phones, etc.). However, power devices for EVs, peripheral monitoring sensors for autonomous driving, and SoCs for driving control have many requirements specific to automobiles. They must be developed by automobile manufacturers and automobile parts manufacturers themselves. This paper describes the status of C, A, S, and E in the first half, and the technical trends of power devices, sensors, and SoC in the second half.
