Title: Hyo-Cheon Kang: Innovator in Photolithography Processes
Introduction
Hyo-Cheon Kang is a notable inventor based in Gyeonggi-do, South Korea. He has made significant contributions to the field of photolithography, holding a total of 4 patents. His work focuses on methods that enhance the analysis and determination of irregularities in photolithography processes.
Latest Patents
One of Hyo-Cheon Kang's latest patents is a method of analyzing photolithography processes. This method involves obtaining an image from a pattern formed on a wafer and measuring the dimensions of that image. The dimensions are then converted into a profile graph, which is divided into low-frequency and high-frequency band profile graphs. Another significant patent is a method of determining the irregularities of a hole. This method sets a center coordinate of an actual hole and obtains inner wall coordinates from that center. The area of the actual hole is determined based on these coordinates, and a virtual hole's radius is calculated. The standard deviation of the inner wall coordinates relative to the virtual hole's circumference line is then calculated to obtain the irregularities of the actual hole.
