Abstract:
A system for reviewing at least one layer of at least one semiconductor wafer for defects, said system being interfaced to a first inspection device which scans the at least one layer of the at least one semiconductor wafer for defects, said first inspection device producing a first set of detected defects from scanning the at least one layer of the at least one semiconductor wafer, said system being interfaced to a review station for reviewing the at least one layer of the at least one semiconductor wafer, said system comprising:(a) a server connected to said first inspection device and said review station, said server comprising a database into which said first set of detected defects is stored, and (b) review client software which interfaces with said review station, said review client software enabling a sample of said first set of detected defects to be extracted from the database using at least one defect sampling condition, said at least one defect sampling condition relating to a particular defect characteristic.
