Title: Yasuo Arai: Innovator in Semiconductor Technology
Introduction
Yasuo Arai is a prominent inventor based in Ibaraki, Japan, known for his significant contributions to semiconductor technology. With a total of five patents to his name, Arai has made notable advancements in the field, particularly in the design and manufacturing of semiconductor devices.
Latest Patents
Arai's latest patents include a semiconductor device featuring a silicon-on-insulator (SOI) substrate. This invention outlines a method for manufacturing a semiconductor device that incorporates an N-type semiconductor layer formed from a high resistance N-type substrate. Within this layer, a P-type well diffusion layer and a P-type extraction layer are established and fixed to ground potential. This configuration ensures that a depletion layer spreading on the P-type well diffusion layer side does not reach the interlayer boundary between the P-type well diffusion layer and the buried oxide film. Consequently, the potential around the surface of the P-type well diffusion layer is maintained at ground potential. When voltages are applied to the backside of the N-type semiconductor layer and a cathode electrode, the channel region at the MOS-type semiconductor formed as a P-type semiconductor layer remains inactive. This design effectively suppresses leakage current that may occur independently of control from the gate electrode of a transistor.
