Title: Isamu Hijikata: Innovator in Semiconductor Technology
Introduction
Isamu Hijikata is a prominent inventor based in Kanagawa, Japan, known for his significant contributions to semiconductor technology. With a total of 17 patents to his name, Hijikata has developed innovative solutions that enhance the efficiency and effectiveness of semiconductor manufacturing processes.
Latest Patents
One of his latest patents is an object handling device designed to successively transfer objects such as semiconductor wafers. This device features first and second collapsible arm units equipped with hands for holding objects. It includes a first drive shaft for selectively extending and contracting the first arm unit, a second drive shaft for the same purpose with the second arm unit, and a third drive shaft that allows for turning both arm units while maintaining their relative positional relationship. The actuator mechanism enables independent angular movement of the drive shafts about their own axes.
Another notable patent is related to plasma taper etching for semiconductor device fabrication. This plasma processing apparatus contains a chamber that houses both a plasma processing region and a plasma generating region. When a semiconductor wafer with surface irregularities is placed in the processing region, a plasma is generated using a processing gas primarily composed of argon. This process etches the corner edges of the lands of the object into a taper shape, while the material removed is deposited between the lands.
