  • Patent number: 4886412
    Abstract: A wafer transport system includes a mobile frame, a wafer cassette conveyor, a wafer support table, and a wafer transfer assembly. The wafer cassette conveyor carries a plurality of wafer cassettes and presents them successively to a transfer location. The wafer transport assembly, including a robotic arm and a vacuum pickup element, is then able to transport individual wafers from the cassettes to the support table. By rotating the support table, a plurality of wafers can be placed in a desired order. The wafer support table may then be moved to a location proximate a processing chamber, such as a chemical vapor deposition reactor, and processed and unprocessed wafers efficiently exchanged by the transport assembly.
