Title: Ichiro Okabe: Innovator in Semiconductor Technology

Introduction

Ichiro Okabe is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on methods of forming fine patterns using silicon-oxide-based films, which are crucial in the manufacturing of semiconductor devices.

Latest Patents

Ichiro Okabe's latest patents include a method of forming a fine pattern using a silicon-oxide-based film and a semiconductor device with a silicon-oxide-based film and method of manufacture thereof. In his first patent, a silicon-oxide-based film is formed directly or through another layer on a substrate. The film is designed to have a nitrogen content of 0.1 atm. % or less. A chemically-amplified photoresist layer is then applied, allowing for the transfer of a mask pattern onto the photoresist layer. This process effectively prevents the generation of tapered corners in the resist pattern near the boundary with the substrate. His second patent describes a method aimed at depositing a silicon-nitride-based anti-reflection film that remains stable at high temperatures and minimizes internal stress. This method also prevents the formation of a rounded corner at the boundary between the photoresist and the substrate during the creation of a chemically-amplified positive resist pattern.
