Abstract: A system, method, and computer program product are provided for identifying fabricated component defects using a local adaptive threshold. In use, images are received for target and reference components of a fabricated device. Additionally, a difference image is generated from the target and reference component images, and defect candidates for the target component are identified from the difference image. Further, for each of the identified defect candidates at a location in the difference image: a threshold is determined based on a local area surrounding the location of the defect candidate, and a signal at the location of the defect candidate is compared to the threshold to determine whether the defect candidate is a defect.

Abstract: Methods and systems for detecting defects on a wafer are provided. One method includes altering one or more design clips based on how the one or more design clips will appear in output generated by a wafer inspection process for a wafer. The method also includes aligning the one or more altered design clips to the output generated for the wafer during the wafer inspection process. In addition, the method includes detecting defects on the wafer based on the output aligned to the one or more altered design clips.
