Abstract:
1. A substrate processing system comprising: a housing defining a chamber; a substrate support having a substrate support surface within the chamber to support a substrate having a surface to be processed; a first plurality of gas distributors, each having a first exit opening into the chamber around the substrate support surface to introduce a first process gas into the chamber; a second plurality of gas distributors, each having a second exit opening into the chamber around the substrate support surface, the second plurality of gas distributors being fluidicly isolated from the first plurality of gas distributors to introduce a second process gas into the chamber, the second process gas being different from the first process gas; a third gas distributor having a body extending into the chamber perpendicular to the substrate support surface, the body including a distal end having a third exit spaced apart from and disposed above the substrate support surface to introduce a third process gas into the chamber; and a fourth gas distributor fluidicly isolated from the third gas distributor, the fourth gas distributor adapted to introduce a gas into the chamber generally centrally above the substrate support surface and outside the third exit.
