Process window centering (PWC) is an efficient methodology to validate or adjust and center the overall process window for a particular lithography layer by detecting systematic and random defects. The PWC methodology incorporates a defect inspection and analysis of the entire die that can be automated to provide timely results. This makes it a good… CONTINUE READING
