Abstract:
In a method of manufacturing a semiconductor light-emitting device made of a II-VI compound semiconductor in which at least more than one kind of elements of Zn, Be, Mg, Cd or Hg are used as a II-group element and at least more than one kind of elements of Se, S, Te are used as a VI-group element and which includes first conductivity type and second conductivity type cladding layers and an active layer between the cladding layers, said method of manufacturing a semiconductor light-emitting device characterized in that a supply ratio VI/II ration of VI-group element and II-group element required when the active layer is epitaxially deposited is selected to be greater than 1.1 and said active layer is deposited epitaxially, and said active layer is comprised of ZnCdSSe.
