ABSTRACT:
A semiconductor light-emitting device is provided. In an InGaN-based semiconductor light-emitting device including an Ag electrode, a semiconductor layer on the contact side of at least the Ag electrode is a dislocation semiconductor layer of which dislocation density is selected to be less than 1×107 (1/cm2) and thereby short-circuit caused by Ag migration generated along this dislocation can be avoided. Thus, this semiconductor light-emitting device is able to solve a problem of a shortened life and a problem with the fraction of defective devices encountered with the InGaN-based semiconductor light-emitting device.
