    摘要: A system and method for annealing a film on a substrate in a processing chamber, including a microwave generator disposed to provide microwaves to an area within the interior of the chamber. The microwaves have a frequency such that the film is substantially absorptive at the frequency but the substrate is not substantially absorptive at the frequency. A waveguide distributes the microwaves over the surface of the film to provide a substantially uniform dosage of microwaves over the surface of the film. The method includes depositing a film on a substrate in the processing chamber. During at least a portion of the time of the depositing step, microwaves are generated having a frequency such that the film has an absorption peak at the frequency but the substrate lacks a substantial absorption peak at the frequency. The microwaves are directed towards the film.
