Patent ID: 7319248

Claim:
A high brightness light emitting diode, comprising: a permanent metal substrate; an adhesive layer formed on said permanent substrate and composed of a pure metal or an alloy with a melting point below 350 degree C.; a reflective mirror formed on said adhesive layer and made from a metal selected from a group consisting of In, Sn, Al, Au, Pt, Zn, Ag, Ge, Ni, Au/Zn, Au/Be, Au/Ge and Au/Ge/Ni, and mixtures of two or more thereof; an n-type cladding layer formed on said reflective mirror, and defining a higher port and a lower port on an upper surface thereof; an active layer with quantum well structure formed on said higher port of said n-type cladding layer; a p-type cladding layer formed on said active layer; a p-GaP layer formed on said p-type cladding layer; a metal contact layer formed on said p-GaP layer; a p-type ohmic contact electrode formed on said metal contact layer; and an n-type ohmic contact electrode formed on said lower port of said n-type cladding layer.
