Abstract:
A substrate processing system for depositing a layer on a substrate, said system comprising:a) a substrate processing chamber in which a dielectric layer is deposited over the substrate and subsequently;b) a gas distribution system coupled to said first and second substrate processing chambers and configured to introduce deposition and etching gases to said first and second substrate processing chambers; andc) a system controller, coupled to said chamber and said gas distribution system, said system controller having a memory storing a computer-readable program for directing the operation of said system, said computer-readable program comprising;a first set of instructions for controlling said gas distribution system to introduce a process gas into said chamber to deposit said dielectric layer over the substrate;a second set of instructions for controlling said gas distribution system to introduce an etchant gas into said chamber to chemically etchback said dielectric layer; anda third set of instructions for controlling said gas distribution system to introduce a sputtering gas into said second chamber to physically etchback said dielectric layer.
