Patent ID: 7691657

Claim:
A fabrication method of a nitride based 3-5 group compound semiconductor light emitting device, comprising: forming a buffer layer above a substrate at a temperature of 500°-700° C.; forming a first In-doped GaN layer above the buffer layer; forming a first electrode contact layer above the first In-doped GaN layer; forming an active layer, comprising a single or multiple quantum well structure, including a low mole In-doped In x Ga 1−x N layer, an In y Ga 1−y N well layer, and an In z Ga 1−z N barrier layer, and the low mole In-doped In x Ga 1−x N layer has an In content smaller than that of the In z Ga 1−z N barrier layer for emitting light above the first electrode contact layer; forming a GaN layer above the active layer at a temperature of 900°-1020° C.; and forming a second electrode contact layer, comprising an In x Ga 1−x N/In y Ga 1−y N super lattice structure layer, above the GaN layer.
