Title: Yoshiaki Okabe: Innovator in Etching Technology

Introduction

Yoshiaki Okabe is a notable inventor based in Toyama, Japan. He has made significant contributions to the field of etching technology, holding 2 patents that showcase his innovative approaches.

Latest Patents

His latest patents include an etching method, etching apparatus, and a ring member. The etching process involves loading a substrate into a processing chamber and mounting it on a table. A ring member, made of the same material as the main component of the etching target film, surrounds the substrate. A processing gas is injected in a shower-like manner from a gas supply unit facing the substrate. The etching target film is then etched using a plasma of the processing gas, while the inside of the processing chamber is evacuated through an exhaust path. This method effectively suppresses the unbalanced distribution of plasma active species near the circumferential edge of the substrate.
