Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A processing tool, comprising:
a housing enclosing a processing chamber;
an input/output port configured to pass a wafer through the housing into and out of the processing chamber;
a wafer transfer system including rails of a gantry system configured to transfer the wafer from the input/output port between a first location in the processing chamber, a second location in the processing chamber, and a third location in the processing chamber, the first, second, and third locations each differing from one another;
a back-side macro inspection imaging system arranged within the processing chamber and arranged along the rails and configured to image a back side of the wafer while the wafer is at the first location;
a first front-side macro inspection imaging system arranged within the processing chamber and arranged along of the rails and configured to image a front side of the wafer while the wafer is at the second location;
a second front-side micro inspection imaging system arranged within the processing chamber and configured to image the front side of the wafer while the wafer is at the third location;
an optical character recognition (OCR) system retained within the processing chamber and arranged along the rails; and
a sorting assembly downstream of the OCR system and comprising a series of slots stacked one over another, with each slot sized to receive a wafer.
