Abstract:
A method of manufacturing a semiconductor device which includes a substrate made of a compound semiconductor, a gate electrode formed on said substrate, and source/drain regions formed in said substrate, said method comprising the steps of:forming said gate electrode on a channel layer of said substrate; forming a film of a specific metal onto said substrate so as to cover at least one of side portions of said gate electrode; reacting said compound semiconductor with said specific metal in solid phase to form at least one solid-phase reaction layer in said substrate; and removing the part of said film which has not been reacted, so that at least one of said source/drain regions is made of said solid-phase reaction layer, wherein said part of said film which has not been reacted is removed by etching, and the gate length of said gate electrode is shortened in the etching process.
