Socionext is a global company formed by the merger of the semiconductor businesses of Fujitsu and Panasonic. Its business involves SoC (System-on-Chip) design, R&D, and sales. It is the world’s top SoC design manufacturer.

Socionext claims to realize the commercialization of 5nm line width semiconductors. This is the first time a Japanese company’s 5-nanometer semiconductor development plan has been made public. Nikkei expects that the company will cooperate with Taiwan Semiconductor Manufacturing Company (TSMC), a semiconductor foundry company, and the development plan will be launched in 2022 at the earliest.

Socionext develops system-on-chip SoC semiconductor chips for pure electric vehicles (EV), driver assistance systems (ADAS), and autonomous driving. However, Socionext does not have its own factory and is a Fabless company specializing in semiconductor development.
