摘要: A method for removing native oxides from a substrate surface is provided. In one embodiment, the method comprises positioning a substrate having an oxide layer into a processing chamber, exposing the substrate to a gas mixture while forming a volatile film on the substrate and maintaining the substrate at a temperature below 65° C., heating the substrate to a temperature of at least about 75° C. to sublimate the volatile film and remove the oxide layer, and depositing a first layer on the substrate after heating the substrate.
