Dual plasma source, lamp heated plasma chamber

Abstract

Methods and apparatus for processing semiconductor substrates are described. A processing chamber includes a substrate support with an in-situ plasma source, which may be an inductive, capacitive, microwave, or millimeter wave source, facing the substrate support and a radiant heat source, which may be a bank of thermal lamps, spaced apart from the substrate support. The support may be between the in-situ plasma source and the radiant heat source, and may rotate. A method or processing a substrate includes forming an oxide layer by exposing the substrate to a plasma generated in a process chamber, performing a plasma nitridation process on the substrate in the chamber, thermally treating the substrate using a radiant heat source disposed in the chamber while exposing the substrate to oxygen radicals formed outside the chamber, and forming an electrode by exposing the substrate to a plasma generated in the chamber.
