Patent ID: 7067401

Claim:
A method of fabricating nitride semiconductors in a Metal-Organic Chemical Vapor Deposition (MOCVD) reactor, the method comprising the following steps of: (a) loading a substrate from the group consisting of sapphire, silicon carbide (SiC), oxide, and carbide into the MOCVD reactor; (b) heating the substrate and injecting Tri-Methyl Gallium (TMG) or Tri-Ethyl Gallium (TEG) on a mixed gas from the group consisting of NH 3 , tertiary-butylamine (N(C 4 H 9 )H 2 ), phenylhydrazine (C 6 H 8 N 2 ), and dimethylhydrazine (C 2 H 8 N 2 ) containing gas and etching gas into the MOCVD reactor; and (c) injecting the gas from the group consisting of NH 3 , tertiary-butylamine (N(C 4 H 9 )H 2 ), phenylhydrazine (C 6 H 8 N 2 ), and dimethylhydrazine (C 2 H 8 N 2 ) into the MOCVD reactor to nitrify the surface of the substrate.
