Method for producing a high-luminance semiconductor light-emitting device capable of operating at a low voltage

摘要

A semiconductor light-emitting device has a light-emitting section comprised of at least a lower clad layer, an active layer and an upper clad layer which are formed on a compound semiconductor substrate and a layer grown on the upper clad layer of the light-emitting section. When growing the current diffusion layer from a crystal interface on the upper clad layer in a lattice mismatching state in which the absolute value of a lattice matching factor DELTAa/a is not lower than 0.25% with respect to the upper clad layer at a crystal interface where the crystal composition changes on the upper clad layer of the light-emitting section, the growth rate at least at the start time of growth is made to be 1.0 mum/h or less.
