Title: Chouhei Okuno: Innovator in Semiconductor Technology

Introduction

Chouhei Okuno is a prominent inventor based in Ibaraki, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of three patents. His work focuses on improving methods and apparatuses related to semiconductor wafer handling and processing.

Latest Patents

Okuno's latest patents include a semiconductor wafer mounting method and a semiconductor wafer mounting apparatus. In this innovative work, a workpiece is unloaded from a wafer-receiving container. A first discriminating sensor detects the front surface of the workpiece and determines whether it is a semiconductor wafer or a spacer. If the workpiece is identified as a wafer, the first discriminating sensor also checks for the presence of protective tape on its front surface. If no protective tape is detected, a second discriminating sensor examines the back surface of the wafer to confirm the absence of protective tape. Another notable patent is the method and apparatus for separating protective tape. This invention involves a first holding table that suction-holds an annular projection of a wafer remaining on its rear face, surrounding a back grinding region. A second holding table is then inserted into a flat portion inside the annular projection to join a separating adhesive tape to the protective tape on the wafer's surface. This process allows for the adhesive tape to be separated from the wafer along with the protective tape.
