Title: Yuji Machiya: Innovator in Photomask Inspection and IC Layout Systems
Introduction
Yuji Machiya is a notable inventor based in Shinjuku-ku, Japan. He has made significant contributions to the fields of photomask inspection and integrated circuit (IC) layout systems. With a total of 3 patents to his name, Machiya continues to push the boundaries of technology.
Latest Patents
One of his latest patents is a photomask inspecting method. This method involves inspecting a photomask with a dummy pattern at a predetermined detection sensitivity. It utilizes photomask pattern data to detect defects and determines the coordinates of these defects. The method discriminates between defects in the design pattern area and those in the dummy pattern area using defect-discriminating data. Each area is examined based on its respective inspection specifications.
Another significant patent is the IC element layout data display system. This system includes a magnetic disk unit for storing IC element layout data. A preprocessor reads the data, divides it into multiple pattern sets, and generates map information that represents the positions of these pattern sets. A pattern retrieving unit accesses the layout data using this map information to obtain graphic information for display. The display unit then presents the retrieved graphic information.
