Patent ID: 7670432

Claim:
A vacuum processing system, comprising: a vacuum processing chamber configured to treat a substrate, the vacuum processing chamber including a first chamber assembly including a process space configured to facilitate material deposition, the first chamber assembly further including a pumping manifold with an extension extending from a part of said first chamber assembly to separate said process space from a transfer space, the extension including an internal channel that connects an inlet of a first vacuum pump in fluid communication with the process space in said vacuum processing chamber via one or more openings in said extension, said one or more openings being positioned below a top surface of a substrate stage connected to said second chamber assembly and configured to support and translate said substrate between a first position in said process space to a second position in said transfer space such that tops of the openings in said extension are positioned below a top surface of the substrate stage when the substrate is in the first position, and a second chamber assembly including the transfer space, the transfer space being configured to facilitate transfer of said substrate into and out of said vacuum processing system; a process material supply system configured to connect in fluid communication with said vacuum processing chamber and configured to introduce a process gas to said process space via a gas injection system; and a process gas supply line configured to establish fluid communication from said process material supply system to said vacuum processing chamber and to permit a flow of process gas from said process material supply system to said process space, and further configured to connect in fluid communication with said first vacuum pump separately from said process space; a primary vacuum line configured to establish fluid communication between said vacuum pump and said vacuum processing chamber and to permit flow of exhaust gases from said process space to said vacuum pump; a second vacuum pump in fluid communication with said second chamber assembly and configured to provide a reduced contaminant environment in said transfer space; and a temperature control system coupled to said substrate stage, and configured to control a temperature of said substrate, a sealing device configured to provide a vacuum seal between said substrate stage and said first chamber assembly when said substrate stage is in said first position, wherein said sealing device is configured to vacuum isolate said process space from said transfer space, wherein the extension comprises a first wall and a second wall, and the first wall is disposed between the process space and second wall, and the interior channel is disposed between the first and second walls, and wherein the first wall is concentric to the second wall such that the internal channel comprises an annular shape curved around the substrate stage.
