Latest Patents

Zhou's latest patents include methods and systems for detecting defects on specimens. One of his notable inventions focuses on computing different candidate reference images from various combinations of images generated by an inspection subsystem. This system combines portions of these candidate reference images to create a final reference image, which is then utilized for defect detection. This method is especially useful for areas of specimens that contain non-resolvable, repeating device patterns, such as cell regions.

Another significant patent addresses defect detection in array regions on specimens. This method involves determining the center of a page break in output generated by an inspection subsystem. The page break separates cell regions that include repeating patterned features. By identifying offsets between the centers of page breaks, Zhou's method effectively detects defects in the array region by applying a defect detection method to the relevant portions of the output.
