Abstract:
1. A method of forming a semiconductor structure comprising forming a first trench and a second trench through a dielectric template material layer on a single crystalline substrate; forming a first template epitaxial semiconductor material portion within said first trench by epitaxy of a first template semiconductor material and forming a second template epitaxial semiconductor material portion within said second trench by epitaxy of a second template semiconductor material, wherein one of the first and second template semiconductor materials is an elemental semiconductor material, and another of said first and second template semiconductor materials is a compound semiconductor material; epitaxially growing a first epitaxial semiconductor portion including a first semiconductor material that is different from said first template semiconductor material on said first template epitaxial semiconductor material portion; epitaxially growing a second epitaxial semiconductor portion including a second semiconductor material that is different from said second template semiconductor material on said second template epitaxial semiconductor material portion; forming at least one dielectric bonding material layer over said first and second epitaxial semiconductor portions; and bonding a handle substrate to said at least one dielectric bonding material layer; and removing said single crystalline substrate, said dielectric template material layer, and said first and second template epitaxial semiconductor material portions.
