Abstract:
1. A semiconductor light emitting device comprising: a substrate; a semiconductor laminate having a base semiconductor layer, a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer sequentially formed on the substrate and divided by an isolation region to provide a plurality of light emitting cells; an intermediate separation layer interposed between the base semiconductor layer and the first conductivity-type semiconductor layer in order to electrically separate the base semiconductor layer and the first conductivity-type semiconductor layer; a plurality of first and second electrodes connected to the first and second conductivity-type semiconductor layers, respectively, of the plurality of light emitting cells; and a wiring unit connecting the first and second electrodes of different light emitting cells such that the plurality of light emitting cells are connected wherein the intermediate separation layer is a nitride layer co-doped with carbon (C) and silicon (Si).
