Claim 9:
10. A processing tool, comprising:
a housing enclosing a processing chamber of the processing tool, wherein an input/output port is included in the housing and is configured to pass wafers into and/or out of the processing chamber within the housing;
a gantry system including rails arranged within the processing chamber and configured to receive the wafers;
a back-side imaging system arranged along the rails of the gantry system within the processing chamber and including a first camera, wherein the wafers are transported by the rails of the gantry system so as to pass the first camera while the wafer is at a first location along the rails within the housing such that the first camera images back sides of the wafers; and
a front-side imaging system arranged along the gantry system within the processing chamber and including a second camera, wherein the wafers are transported by the gantry system so as to pass the second camera while the wafer is at a second location along the rails within the housing such that the second camera images front sides of the wafers, the second location differing from the first location within the housing.
