    摘要: An apparatus and method for a gas distribution plate is provided. The gas distribution plate has a first manifold which includes a plurality of concentric channels for providing at least two distinct gases to a processing zone above a substrate. A portion of the plurality of channels perform a thermal control function and are separated from the remaining channels, which provide separated gas flow channels within the gas distribution plate. The gas flow channels are in fluid communication with a second manifold which includes a plurality of concentric rings. Apertures formed in the rings are in fluid communication with the gas flow channels and the processing zone. The gases are provided to the processing zone above the substrate, and do not mix within the gas distribution plate.
