Latest Patents

One of his latest patents is a wafer backside defect detection method and apparatus. This invention includes a process where a peripheral edge area of a wafer backside image is cropped off to identify abnormal regions. If the total area of the top N abnormal regions exceeds 10% of the wafer's area, it indicates a roughness defect. Conversely, if it is less than 1% and the largest abnormal region exceeds a predetermined length, it suggests a scratch defect. Another significant patent is an automatic detection method and system for identifying cracks on wafer edges. This method involves obtaining several wafer images, creating a template image, and comparing each wafer image to detect edge cracks through a series of image processing steps.
