  • Patent number: 6609869
    Abstract: A substrate processing system includes a substrate handling chamber and an integrated load lock chamber. The load lock chamber has a gated inlet for the transfer of a substrate into and out of the load lock chamber and a gated port for transferring a substrate between the load lock chamber and the substrate handling chamber. The substrate handling chamber includes a staging shelf that is positioned above the load lock chamber and a substrate handler for moving a substrate between the load lock chamber and the staging shelf. In use, a first substrate is placed at a load lock station that is located inside the load lock chamber. The first substrate is moved from the load lock station to a staging shelf located inside the substrate handling chamber. A second substrate is moved from a cooling station in the substrate handling chamber to the load lock station. A third substrate is moved from a substrate processing chamber to the cooling station.
