Patent ID: 8405113

Claim:
A semiconductor light-emitting device comprising: a reflective electrode provided on a support and forming a reflective surface; a first cladding layer provided on said reflective electrode; a light-emitting layer provided on said first cladding layer; a second cladding layer provided on said light-emitting layer and having a terrace structure formed of recesses and protrusions, a light-extracting structure having projections and depressions being formed on top surfaces of said protrusions and bottom surfaces of said recesses; and surface electrodes provided on the top surfaces of said protrusions, wherein said second cladding layer has a stacked structure on said light-emitting layer, said stacked structure including a first current-spreading layer, a first light-extracting layer provided on said first current-spreading layer and having the light-extracting structure formed on the bottom surfaces of said recesses, a second current-spreading layer provided on said first light-extracting layer, and a second light-extracting layer provided on said second current-spreading layer and having said light-extracting structure formed on the top surfaces of said protrusions, and said first light-extracting layer and said second light-extracting layer have lower light absorptance and higher resistance than said first current-spreading layer and said second current-spreading layer.
