Abstract

A method of removing an amorphous oxide from a surface of a monocrystalline substrate is provided. The method includes depositing a passivation material overlying the amorphous oxide. The monocrystalline substrate is then heated so that the amorphous oxide layer decomposes into at least one volatile species that is liberated from the surface.
