Title: Masahiro Ohashi: Innovator in Semiconductor Technology
Introduction
Masahiro Ohashi is a prominent inventor based in Aichi, Japan, known for his significant contributions to the field of semiconductor technology. With a total of two patents to his name, Ohashi has made strides in the production of Group III nitride compound semiconductor elements and devices.
Latest Patents
Ohashi's latest patents include a method for producing a Group III nitride compound semiconductor element. This innovative method involves growing an epitaxial layer containing a Group III nitride compound semiconductor using a different kind of substrate as an epitaxial growth substrate. The process includes adhering a supporting substrate to the top surface of the epitaxial growth layer through a conductive layer and removing the epitaxial growth substrate by laser lift-off. Additionally, a first groove is formed to act as an air vent during the joining of the epitaxial layer and the supporting substrate. The epitaxial layer is then divided into chips, and an insulating protective film is applied to the outer peripheral side surface of each chip.
Another patent focuses on a method for producing a Group III nitride-based compound semiconductor device. This method includes forming trenches that extend from the top surface of a stacked structure to the interface between the epitaxial growth substrate and the bottom surface of the epitaxial layer. The trenches help divide the epitaxial layer into extended device areas and stress relaxation areas, facilitating the laser lift-off process.
