Claim Text:
1. A method of fabricating a semiconductor light emitting device, comprising: forming a first conductivity type nitride semiconductor layer; forming an active layer on the first conductivity type nitride semiconductor layer; and forming a second conductivity type nitride semiconductor layer on the active layer, wherein the active layer has a structure in which a plurality of quantum barrier layers and a plurality of quantum well layers containing indium are alternately stacked, the plurality of quantum barrier layers and the plurality of quantum well layers are divided into a plurality of groups according to a growth direction, and the plurality of groups respectively have at least one quantum barrier layer and at least one quantum well layer and include a first group adjacent to the first conductivity type nitride semiconductor layer and a second group adjacent to the second conductivity type nitride semiconductor layer, and a quantum barrier layer of the first group is grown at a temperature higher than a growth temperature of a quantum barrier layer of the second group, a quantum well layer of the first group having an indium composition ratio lower than that of a quantum well layer of the second group.
