Abstract

Official abstract text for this publication.

A semiconductor light-emitting device includes a lamination of semiconductor layers including a first layer of a first conductivity type, an active layer, and a second layer of a second conductivity type; a transparent conductive film formed on a principal surface of the lamination and having an opening; a pad electrode formed on part the opening; and a wiring electrode connected with the pad electrode, formed on another part of the opening while partially overlapping the transparent conductive film; wherein contact resistance between the transparent conductive film and the lamination is larger than contact resistance between the wiring electrode and the lamination. Field concentration at the wiring electrode upon application of high voltage is mitigated by the overlapping transparent conductive film.
