Patent ID: 7651583

Claim:
A processing system for trimming a feature on a substrate comprising: a process chamber having a lower chamber portion that chemically alters exposed surface layers on a substrate, and an upper chamber portion that thermally treats said chemically altered surface layers on said substrate; a lower wall temperature control unit coupled to said lower chamber portion and configured to control the temperature of said lower chamber portion; an upper wall temperature control unit coupled to said upper chamber portion and configured to control the temperature of said upper chamber portion; a gas injection system coupled to said lower chamber portion and configured to introduce one or more process gases to said lower chamber portion; a gas distribution system temperature control unit coupled to said gas injection system and configured to control the temperature of said gas injection system; a temperature controlled substrate holder fixedly mounted within said lower chamber portion and configured to support said substrate on an upper surface thereof in said lower chamber portion and control a temperature of said substrate when in contact with said temperature controlled substrate holder; a substrate lift-pin assembly coupled to said temperature controlled substrate holder, and configured to vertically translate said substrate between said upper surface of said temperature controlled substrate holder and a transfer plane in said lower chamber portion; a substrate lifting assembly, separate from said temperature controlled substrate holder, movably coupled to said process chamber, and configured to recede beneath said upper surface of said temperature-controlled substrate holder, isolate said lower chamber portion from said upper chamber portion via a chamber lip, support said substrate on a substrate lip at a peripheral edge of said substrate and transport said substrate between said lower chamber portion and said upper chamber portion, to and from said transfer plane, and to and from said upper surface of said temperature-controlled substrate holder; and a pumping system coupled to said lower chamber portion and said upper chamber portion.
