Abstract:
1. A method of removing material on a substrate, comprising: disposing a substrate on a temperature controlled substrate holder mounted within a temperature controlled process chamber, said temperature controlled process chamber configured to facilitate a non-plasma environment, and said temperature controlled substrate holder configured to support said substrate, such that a surface of said substrate is oriented to be treated by said non-plasma environment, and configured to control a temperature of said substrate when said substrate is resting on an upper surface of said temperature controlled substrate holder; evacuating said temperature controlled process chamber using a pumping system coupled to said temperature controlled process chamber; chemically treating said substrate within said temperature controlled process chamber using a chemical treatment system coupled to said temperature controlled process chamber by exposing said substrate to a process gas composition selected to chemically alter exposed surface layers on said substrate; setting a temperature of said substrate to a substrate temperature less than 100 degrees C. during said chemically treating; following said chemically treating, thermally treating said substrate within said temperature controlled process chamber using a thermal treatment system coupled to said temperature controlled process chamber by heating said substrate to a temperature sufficient to cause evaporation of said chemically altered surface layers, wherein said substrate temperature is elevated to a temperature greater than or equal to 100 degrees C.; and performing said chemically treating and said thermally treating in tandem to remove material from said substrate.
