Claim Text:
1. A method of fabricating a nitride semiconductor light emitting device, the method comprising: forming a first buffer layer above a substrate; recrystallizing the first buffer layer at a temperature higher than a growth temperature of the first buffer layer; forming a second buffer layer containing indium above the first buffer layer; forming a third buffer layer containing indium and configured to directly contact the second buffer layer; forming an indium-doped GaN layer above the third buffer layer; forming a first nitride semiconductor layer configured to directly contact the indium-doped GaN layer; forming an active layer above the first nitride semiconductor layer; and forming a second nitride semiconductor layer above the active layer; wherein the first nitride semiconductor layer is disposed between the indium-doped GaN layer and the active layer, and wherein the second buffer layer has a growth temperature between the growth temperature of the first buffer layer and the temperature of the recrystallizing of the first buffer layer.
