Patent ID: 6846686

Claim:
A method of manufacturing a semiconductor light-emitting device, comprising: forming a first semiconductor layer including formation of a buffer layer of a second conductivity type on a second substrate of the second conductivity type, formation of a current diffusion layer of the second conductivity type on said buffer layer, formation of a second cladding layer of the second conductivity type on said current diffusion layer, formation of an active layer on said second cladding layer, formation of a first cladding layer of a first conductivity type on said active layer, and formation of a second bonding layer of the first conductivity type on said first cladding layer, each of said second substrate and said buffer layer consisting essentially of a GaAs material, each of said current diffusion layer, said active layer and said first and second cladding layers consisting essentially of a material represented by a general formula In x Ga y Al z P, where x+y+z=1, and 0≦x, y, z≦1, and said second bonding layer consisting essentially of an InGaP material; forming a second semiconductor layer including formation of a first bonding layer of the first conductivity type on a first substrate of the first conductivity type, each of said first substrate and said first bonding layer consisting essentially of a GaP material; bonding said first semiconductor layer to said second semiconductor layer with said first bonding layer and said second bonding layer forming a bonding interface; and removing said second substrate and buffer layer.
