Abstract
A semiconductor light emitting device includes a substrate and semiconductor overlying layers formed on the substrate. A light emitting layer is formed in the semiconductor layer so as to emit light. The substrate is transmittable of the light emitted by the light emitting layer. A light reflecting layer is formed on a part of a back surface of the substrate. As a result, a semiconductor light emitting device is obtainable by easily dividing a wafer having thereon a light emitting film through recognizing, from a wafer back side, semiconductor layer chip pattern formed overlying the main surface of the wafer.
