Abstract:
A method of manufacturing a semiconductor light-emitting device comprising the steps of:forming a first semiconductor layer being made of Al.sub.X In.sub.Y Ga.sub.1-X-Y N (including X=0, Y=0, X=Y=0);forming a light-emitting layer of superlattice structure being formed on the first semiconductor layer by laminating a barrier layer being made of In.sub.Y1 Ga.sub.1-Y1 N (Y1.gtoreq.0) and a quantum well layer being made of In.sub.Y2 Ga.sub.1-Y2 N (Y2>Y1 and Y2>0); andforming a second semiconductor layer being made of Al.sub.A In.sub.B Ga.sub.1-A-B N (including A=0, B=0, A=B=0) on the light emitting layer;wherein an uppermost barrier layer, which is an uppermost layer of the light-emitting layer, is formed thicker than the other barrier layers.
