Abstract: A method of fabricating a semiconductor device includes plasma etching a portion of a plurality of metal dichalcogenide films comprising a compound of a metal and a chalcogen disposed on a substrate by applying a plasma to the plurality of metal dichalcogenide films. After plasma etching, a chalcogen is applied to remaining portions of the plurality of metal dichalcogenide films to repair damage to the remaining portions of the plurality of metal dichalcogenide films from the plasma etching. The chalcogen is S, Se, or Te.
