Semiconductor light-emitting device and manufacturing method for the same

Abstract

In a semiconductor light-emitting device including a substrate, a first compound semiconductor layer including an active layer formed on the substrate, a second compound semiconductor layer of a ridge type formed on the first compound semiconductor layer, and a protective film formed above the first compound semiconductor layer on both sides of the second compound semiconductor layer, the disclosed semiconductor light-emitting device has a current blocking layer formed above the first compound semiconductor layer outside the protective film. This semiconductor light-emitting device is with a high production yield since readily cleaved and assembled, with adequately squeezed currents, and with, when assembled in the junction-down type, a high output and a longer life span.
