Abstract

On an entire surface of a substrate of sapphire having a projection with a width in the lateral direction of approximately 10 .mu.m thereon, a first semiconductor layer of Al.sub.y Ga.sub.1-y N and a second semiconductor layer of In.sub.x Ga.sub.1-x N are successively grown by MOVPE. In this manner, an island-like stacked substance including the isolated first semiconductor layer and the isolated second semiconductor layer can be formed on the top surface of the projection of the substrate.
