Claim Text:
1. A method of automated optical inspection (AOI) for a plurality of unique semiconductor packages comprising: providing a plurality of semiconductor die formed as a reconstituted wafer; forming a plurality of unit specific patterns by forming a unit specific pattern over each of the plurality of semiconductor die, wherein each of the unit specific patterns is customized to fit its respective semiconductor die; acquiring a plurality of images by acquiring an image for each of the plurality of unit specific patterns; creating a plurality of unique reference standards by creating a unique reference standard for each of the plurality of unit specific patterns; detecting defects in the plurality of unit specific patterns by comparing one of the plurality of unique reference standards to a corresponding one of the plurality of images for each of the plurality of unit specific patterns; and singulating the reconstituted wafer to form the plurality of unique semiconductor packages.
