  • Controlled silicon doping of III-V compounds by thermal oxidation of silicon capping layer
    Patent number: 5188978
    Abstract: The method for silicon doping of III-V compounds by depositing a layer of silicon on the surface of a III-V compound substrate and subjecting the silicon capped substrate to thermal oxidation at temperatures and in an oxidizing atmosphere sufficient to cause silicon to diffuse into the substrate. A subsequent annealing step enhances the electrical characteristics of the diffused region.
