Abstract:
A method of manufacturing a semiconductor light emitting device, by supplying a reactive gas to a substrate placed in an MOCVD apparatus, comprising the steps of:(a) forming an n-type layer of gallium-nitride based compound semiconductor on said substrate;(b) forming a first semiconductor sublayer of In.sub.x Ga.sub.1-x N (0<x.ltoreq.0.5) on said n-type layer by introducing trimethyl-indium into the reactive gas;(c) forming a second semiconductor sublayer of In.sub.z Ga.sub.1-z N (0.ltoreq.z<x) on said first semiconductor sublayer by reducing the supply ratio of trimethyl-indium in the reactive gas;(d) forming an active layer formed by said first semiconductor sublayer and said second semiconductor sublayer alternately overlaid one another by repeating the process of the steps (b) and (c); and(e) forming subsequently a p-type layer of gallium-nitride based compound semiconductor on said active layer.
