Automotive semiconductors in the CASE era

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.
