Introduction

Yukio Komatsu is a prominent inventor based in Tokyo, Japan, known for his contributions to semiconductor manufacturing. He holds a total of 4 patents, showcasing his expertise and innovative approach in the field.

Latest Patents

One of his latest patents is a method for manufacturing SIMOX wafers. This method focuses on reducing the roughness of an SOI layer and the interface between the SOI layer and a BOX layer. The process involves forming a first ion-implanted layer containing highly concentrated oxygen within a wafer, followed by the formation of a second ion-implanted amorphous layer. A high-temperature heat treatment is then applied, transforming the first and second ion-implanted layers into a BOX layer. This treatment is conducted at temperatures between 1300°C and just below the silicon melting point in an oxygen-rich atmosphere. Another significant patent details a method for manufacturing SIMOX wafers that achieve a thin BOX layer without compromising productivity or quality. This method includes forming a first ion-implanted layer in a silicon wafer, creating a second ion-implanted layer in an amorphous state, and conducting a high-temperature heat treatment in an oxygen-containing atmosphere.
