Title: Kenji Itou: Innovator in Semiconductor Technology

Introduction

Kenji Itou is a prominent inventor based in Gunma, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to materials and devices used in semiconductor processing.

Latest Patents

One of Kenji Itou's latest patents is a vessel made from pyrolytic boron nitride (PBN). This novel vessel, such as crucibles, is highly resistant to exfoliation of the surface layer and is suitable for use as a container for the melt in the Czochralski single crystal growing of III-V Group compound semiconductor single crystals. The invention emphasizes an improvement in the serviceable life of the vessel, characterized by specific values of parameters including density, which should range from 1.90 to 2.05 g/cm³, and the intensity ratio of X-ray diffraction peaks representing the degree of orientation and heat conductivity coefficient.

Another significant patent is the triple-layered ceramic heater. This improved double-layered ceramic heater is designed for heating a semiconductor silicon wafer during the processing of semiconductor devices. It addresses issues found in prior art ceramic heaters regarding service life and contamination of silicon wafers. Unlike conventional ceramic heaters, this innovative design features a substrate plate of silicon nitride and a heater element layer of graphite formed by the CVD method, eliminating elements that could act as disturbing dopants in the semiconductor.
