This project worked toward developing a new generation of semiconductors by combining silicon and gallium arsenic perfect-crystal formation and static-induction control technologies. Static induction ...

The static induction transistor was responsible for getting Yamaha into semiconductor manufacturing. Invented by a professor at Tohoku University, Jun’ichi Nishizawa, SITs had the advantage over other ...

The main theme of this project was to fill in the technological gap between the submillimeter and infrared wavelengths – the tetrahertz (1012 Hz) region – for the further development of ...
