In accordance with one embodiment of the invention, a load cup mechanism is provided for loading and unloading apparatus such as a CMP apparatus. The load cup mechanism, configured to load a work piece into and to unload a work piece from the apparatus, comprises a load cup arm configured to pivot about an axis between a load position aligned with the apparatus and an off-load position. A work piece platform is coupled to an end of the load cup arm and a plurality of lift fingers and a plurality of guide fingers, configured to support and center a work piece, are spaced about the work piece platform. A plurality of guide posts are spaced apart about the periphery of the work piece platform and are configured to align the work piece platform, in the load position, to the processing apparatus.

A wafer processing system employing a single-wafer load lock with integrated cooling unit is disclosed. The small volume of the single-wafer load lock allows for fast pump down and vent cycles. By integrating a cooling unit within the load lock, system throughput is further increased by eliminating the need to move a newly processed wafer to a separate cooling unit before moving the wafer to the load lock.
