Overview
Outside leading-edge logic and memory, Japan remains a major producer of devices for power conversion, light and sensing. Power semiconductors for electric vehicles, trains and industrial drives are a particular strength, with several companies investing in SiC.
This group includes power device makers, LED and laser diode makers, an automotive supplier that makes its own semiconductors, and electronic component makers whose products include sensors, MEMS and RF modules.
