Method of fabricating opto-electronic device

摘要

A method of fabricating opto-electronic device includes steps of introducing a first reacting gas flow, a second reacting gas flow and (a) dopant(s) into a reactor to form epilayer(s) on a substrate wherein the ratio of the first reacting gas and the second reacting gas is different in each reacting stages. By providing suitable epilayer growth conditions which need neither expensive equipment nor highly technical steps, high quality doped ZnSe can be obtained and fabricating pure blue light light-emitting diode becomes possible.
