Abstract

High quality epitaxial layers (26) of compound semiconductor materials can be grown overlying large silicon wafers (22) by first growing an accommodating buffer layer (24) on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer (28) of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. Utilizing this technique permits (20) the fabrication of thin film non-volatile memory elements on a monocrystalline silicon substrate.
