Patent ID: 8785965

Claim:
A nitride-based semiconductor light-emitting device having a nitride-based semiconductor multilayer structure, wherein the nitride-based semiconductor multilayer structure comprises: an active layer including an Al a In b Ga c N crystal layer (where a+b+c=1, a≧1, b≧0 and c≧0); an overflow suppressing layer; and an Al f Ga g N layer (where f+g=1, f≧0, and g≧0), wherein the overflow suppressing layer is arranged between the active layer and the Al f Ga g N layer, a portion of the overflow suppressing layer is obtained by doping Al d Ga e N (where d+e=1, d>0, e≧0, and f<d) with In at a concentration of 1×10 16 atoms/cm 3 to 8×10 18 atoms/cm 3 , an In concentration of the overflow suppressing layer other than the portion of the overflow suppressing layer is less than 1×10 16 atoms/cm 3 , peak of the concentration of In with which the Al d Ga e N is doped is within the overflow suppressing layer, and the peak of the concentration of In is not at a face of the overflow suppressing layer.
