Title: Mitsuru Ishikawa: Innovator in Etching Technology

Introduction

Mitsuru Ishikawa is a notable inventor based in Yamanashi, Japan. He has made significant contributions to the field of etching technology, particularly through his innovative methods that enhance the etching process.

Latest Patents

Ishikawa holds 1 patent for an etching method that involves etching a target film formed on a substrate within an airtight processing chamber. This method utilizes a processing gas that contains CF, N, and Ar. The etching target film consists of an upper organic polysiloxane film and a lower inorganic SiO film. The flow rate ratio of CF and N in the processing gas is crucial, as it must be maintained within the range of 1 ≤ (N flow rate/CF flow rate) ≤ 4. Deviating from this range can lead to undesirable outcomes, such as etching stops or poor etching shapes.
