Abstract:
A process for production of a semiconductor compound by means of a metal organic vapor phase epitaxy method, comprising:contacting a cooled metallic member at a position upstream of a substrate for growing the semiconductor compound with a flow of a raw material gas,wherein the semiconductor compound is a Group III-V semiconductor represented by the formula:In.sub.x Ga.sub.y Al.sub.z Nwherein x+y+z=1, 0.ltoreq.x.ltoreq.1, 0.ltoreq.y.ltoreq.1, and 0<z .ltoreq.1; and contains an InGaN layer and an AlGaN layer thereon, wherein the InGaN layer has a film thickness of not less than 5 angstroms and not more than 300 angstroms and is sandwiched between two layers having a band gap larger than that of the InGaN layer, said metallic member being cooled to a temperature of not higher than 300.degree.
