Title: Hiroyuki Ikuta: Innovator in Plasma Processing Technology

Introduction

Hiroyuki Ikuta is a prominent inventor based in Nirasaki, Japan. He has made significant contributions to the field of plasma processing technology, holding a total of 6 patents. His work focuses on innovative methods and devices that enhance the efficiency and effectiveness of plasma processing.

Latest Patents

Ikuta's latest patents include a cleaning method and a plasma treatment device. The cleaning method is designed for cleaning a plasma processing apparatus that performs plasma processing on a substrate. This method involves forming a protective film in the plasma generation region by generating plasma while supplying a film-forming gas into the processing container. The cleaning process then involves cleaning the interior of the processing container where the protective film has been formed by generating plasma while supplying a cleaning gas.

Another notable patent is the plasma processing method and apparatus. This method arranges a substrate in a region away from a microwave plasma generation region in a chamber. It sets the pressure in the chamber to 1 Torr or higher and introduces microwaves from a microwave plasma source, generating microwave plasma by introducing a processing gas containing a reducing gas. Active species are then diffused from the microwave plasma to the substrate side, while high-frequency power is applied to the substrate to generate cathode-coupled plasma near the substrate.
