Introduction

Yoshihide Tada is a prominent inventor based in Chiba, Japan, known for his significant contributions to semiconductor technology. With a total of 2 patents, Tada has developed innovative methods that enhance the manufacturing and functionality of semiconductor devices.

Latest Patents

Tada's latest patents include a manufacturing method for semiconductor devices with source/drain formed. This method involves creating a projection in a substrate through anisotropic etching, where a transistor is contained within the projection. The central portion of the projection, covered with a gate electrode, serves as the channel region, while drain and source regions are formed on either side through oblique ion implantation. This technique eliminates the need for an oxide insulating layer below the transistor, simplifying the manufacturing process.

Another notable patent is for a semiconductor device of band-to-band tunneling type. This device features a silicon substrate and a first gate electrode formed by a highly doped surface region. It includes multiple layers of silicon oxide films and a thin silicon film, which contains P and N type regions to create a PN junction. When a gate bias voltage is applied, a significant band bend is produced, allowing for a large tunneling current to be obtained.
