Title: Eiichi Shimizu: Innovator in Sputtering Technology

Introduction

Eiichi Shimizu is a notable inventor based in Miyagi, Japan. He has made significant contributions to the field of sputtering technology, holding a total of 3 patents. His work focuses on improving the production methods and efficiency of sputtering target assemblies.

Latest Patents

One of his latest patents is the "Sputtering target assembly production method." This method involves producing a sputtering target assembly that consists of a target member used for sputtering and a backing plate bonded to the target member. The assembly is designed to have high adherence strength, bonding strength, and sufficient tensile strength, even under high temperatures. The bonding surfaces of the target member and the backing plate are made flat, achieving an arithmetic mean roughness Ra of 0.01 to 1.0 µm before solid phase diffusion bonding is carried out.

Another significant patent is the "Contoured sputtering target." This invention includes a target member of sputtering material with a top surface, bottom surface, and outer peripheral surface. The design features one or more contoured annular regions on the top surface that extend radially inwardly from the outer peripheral surface. This configuration reduces the generation of contaminating particles from nodules that may form during sputtering operations.
