Abstract:
A system for processing a semiconductor wafer comprising:a loading station for semiconductor wafers; a plurality of single-wafer load locks, each of the load locks comprising a floor and a ceiling and containing one and only one wafer holder, the wafer holder being adapted to hold one and only one wafer, each of the load locks further containing a cooling unit and a plurality of pins for supporting the wafer, said cooling unit comprising a channel for circulating a liquid coolant; a first robot for moving the wafer between the loading station and the single-wafer load locks; a semiconductor processing reactor; and a transfer chamber in communication with the reactor and the single-wafer load locks, the transfer chamber comprising a second robot for moving the wafer between the single-wafer load locks and the reactor, wherein said pins define wafer pickup and placement points for said first and second robots, said placement and pick-up points being fixed and coincident with each other.
