Patent ID: 8536598

Claim:
A semiconductor light emitting device comprising: a GaAs substrate structure including a GaAs layer, a first metal buffer layer disposed on a surface of the GaAs layer, a first metal layer disposed on the first metal buffer layer, a second metal buffer layer disposed at a back side of the GaAs layer, and a second metal layer disposed on a surface of an opposite side of the GaAs layer of the second metal buffer layer; and a light emitting diode structure disposed on the GaAs substrate structure and including a third metal layer, a metal contact layer disposed on the third metal layer, a p type cladding layer disposed on the metal contact layer, a multi-quantum well layer disposed on the p type cladding layer, an n type cladding layer disposed on the multi-quantum well layer, and a window layer disposed on the n type cladding layer, wherein the GaAs substrate structure and the light emitting diode structure are bonded by using the first metal layer and the third metal layer.
