Title: Masamichi Inenaga: Innovator in Wafer Technology
Introduction
Masamichi Inenaga is a prominent inventor based in Fukuoka, Japan. He has made significant contributions to the field of wafer technology, holding a total of 5 patents. His innovative work has advanced the methods and apparatus used in the semiconductor industry.
Latest Patents
Inenaga's latest patents include a wafer pre-alignment apparatus and method. This invention features a wafer rotating member, a rotation detecting member, and a light emitting member that emits light toward the periphery of the wafer. It also includes a COD linear sensor for detecting the edge position of the wafer, allowing for the acquisition of orientation flat position, notch position, and center position based on the detected edge position. Additionally, the apparatus incorporates an up-down counter for converting signals from the rotation detecting member into rotating position information.
Another notable patent is the absolute encoder and absolute value signal generation method. This encoder consists of a first memory that stores an absolute value signal produced at regular intervals, representing an absolute position. A second memory retains a previous absolute value signal, while a comparing/calculating section analyzes the two signals to produce a difference amount. The process includes dividing this difference amount within the producing time period of the first absolute value signal and generating an interpolated absolute value signal.
