Publication number: 20220230281Abstract: Proposed is a technique that can detect a random noise component at high accuracy without measurement pattern limitation and enables edge roughness measurement at higher accuracy. According to this disclosure, pattern matching and edge position correction are performed with respect to each of the left edge and the right edge of a line pattern in an obtained line pattern image, and an image with no roughness is generated. A PSD value is measured from the image, and the average PSD value of all the frequencies is determined as a random noise component, so that the random noise component can be detected at high accuracy. Further, the PSD value (random noise component) is subtracted from the PSD value of an original image, thereby measuring edge roughness at high accuracy.Type: ApplicationFiled: December 8, 2021Publication date: July 21, 2022Inventors: Toshimasa Kameda, Kei Sakai, Junichi Kakuta
