  • Patent number: 12190500
    Abstract: Methods and systems for detecting defects on a specimen are provided. One system computes different candidate reference images from different combinations of images of the specimen generated by an inspection subsystem and combines different portions of the candidate reference images without modification to thereby generate a final reference image. The final reference image is then used for defect detection, which may be single or double detection. The embodiments are particularly useful for defect detection in areas of specimens including only non-resolvable, repeating device patterns, like cell regions, but may be used for inspection of other types of areas as well.

  • Publication number: 20240255448
    Abstract: Methods and systems for detecting defects in an array region on a specimen are provided. One system includes an inspection subsystem configured for generating output responsive to patterned features formed in an array region on a specimen. The system also includes a computer subsystem configured for determining if a pitch of the patterned features in the output is an integer of pixels in a detector of the inspection subsystem that generated the output. When the pitch is not an integer of the pixels, the computer subsystem is configured for interpolating the output to generate interpolated output having a modified pitch of the patterned features in the interpolated output that is an integer of the pixels. The computer subsystem is also configured for detecting defects in the array region by applying a defect detection method to the interpolated output.
