Title: Akira Bandoh: Innovator in Semiconductor Technology

Introduction

Akira Bandoh is a notable inventor based in Chichibu, Japan. He has made significant contributions to the field of semiconductor technology, particularly in the development of p-type silicon carbide (SiC) epitaxial wafers. With a total of 3 patents to his name, Bandoh's work has advanced the manufacturing processes of compound semiconductors.

Latest Patents

One of Bandoh's latest patents is for a method of producing a p-type SiC epitaxial wafer. This method involves setting an input raw material C/Si ratio, which is the ratio between the carbon and silicon elements in a feedstock gas. The process aims to obtain a p-type SiC epitaxial wafer with an aluminum dopant concentration of at least 1×10 cm. The method includes forming a p-type SiC epitaxial film on a substrate in a film-forming atmosphere that comprises the feedstock gas, a chlorine-based gas, and a dopant gas containing aluminum and carbon. The input raw material C/Si ratio is crucial as it differs from the total gas C/Si ratio and is set to 0.8 or less.

Another significant patent involves an apparatus for manufacturing compound semiconductors using a metal-organic chemical vapor deposition (MOCVD) method. This apparatus features a reaction container and a holder that supports the substrate on which the compound semiconductor layer is formed. The design ensures that temperature distribution on the substrate surface is optimized, thereby suppressing deviations in the in-plane averaged light emission wavelength from the target value.
