Abstract
In the fabricating of a light emitting device, a light emitting layer portionand a current spreading layerrespectively composed of a Group III-V compound semiconductor, are stacked on a single crystal substrate. The light emitting layer portionis formed by a metal organic vapor-phase epitaxy process, and the current spreading layer, on such light emitting layer portion, is formed to have conductivity type of n-type by a hydride vapor-phase epitaxy process.
