Patent ID: 8492243

Claim:
A method for producing a semiconductor structure, comprising: a) providing a 3C—SiC semiconductor layer structure containing an exposed, monocrystalline 3C—SiC layer generated by implantation of carbon in silicon on a silicon substrate, b) applying an epitaxial layer of a gallium nitride compound semiconductor suitable for the generation of optoelectronic components onto the 3C—SiC semiconductor layer structure, c) depositing an electrically conductive reflective metal film directly onto the gallium nitride compound semiconductor epitaxial layer to form a metal reflective film coated gallium nitride layer, d) removing the silicon substrate and 3C—SiC layer; and e) bonding the surface of the gallium nitride layer which formerly was in contact with the 3C—SiC layer onto a second substrate comprising a metal or metal alloy with a reflectivity greater than 80%, or onto a transparent or partially transparent substrate.
