PROCESS FOR PREPARING ELECTROLUMINESCENT DEVICE OF COMPOUND SEMICONDUCTOR

摘要

A process for preparing an electroluminescent device of a compound semiconductor comprising a step (A) of epitaxially forming over a semiconductor substrate an electroconductive layer of a compound semiconductor and an electroluminescent layer of a p-n junction type compound semiconductor placed over the electroconductive layer and a step (B) of forming a pair of ohmic electrodes as electrically connected to each of said layers, both of the steps (A) and (B) being performed by using molecular beam growth under the irradiation with a light beam.
