Abstract:
1. An apparatus for processing a substrate, comprising: a process chamber having a substrate support disposed therein to support a processing surface of a substrate at a desired position within the process chamber; a first inlet port to direct an initial flow of a first process gas over the processing surface of the substrate from one end of the substrate towards an opposite end of the substrate in a first direction; a second inlet port to direct an initial flow of a second process gas over the processing surface of the substrate in a second direction having an azimuthal angle greater than zero with respect to the first direction, wherein the azimuthal angle measured between the first direction and the second direction with respect to a central axis of the substrate support is up to about 145 degrees, and wherein the second direction is angled towards the processing surface; and an exhaust port disposed opposite the first inlet port to exhaust the first and second process gases from the process chamber.
