摘要: A method of in-situ cleaning a native oxide layer from the surface of a silicon wafer positioned in a vacuum chamber that is substantially free of oxidizing species by passing at least one non-oxidizing gas over the native oxide layer at a wafer cleaning temperature between about 650.degree. C. to about 1025.degree. C. for a sufficient length of time until such native oxide layer is removed.
