Title: Hyung-Suk Cho: Innovator in Defect Imaging Technology

Introduction

Hyung-Suk Cho is a prominent inventor based in Hwaseong, South Korea. He is known for his significant contributions to the field of defect imaging technology. With a total of 6 patents to his name, Cho has made remarkable advancements in the detection and classification of defects in substrates.

Latest Patents

Among his latest patents are the "Defect Imaging Apparatus" and the "Method of Automatic Defect Classification." The defect imaging apparatus includes a chamber with a stage for securing a substrate that has at least one process defect and reference defects. It features a position controller that corrects the conversion position of the process defect by accounting for imaging errors. Additionally, it generates an irradiation position for the process defect and utilizes an image signal generator to create an image signal by detecting charged particles. The imaging device then processes this signal to produce a defect image. The method of automatic defect classification involves detecting defective parts from a substrate and classifying defect types using scanning electron microscope (SEM) images. This method enhances the accuracy of defect classification by defining defects of interest and applying specific rules for analysis.
