Abstract

A semiconductor device includes an oxide semiconductor layer, disposed over a substrate. A source electrode of a metal nitride is disposed on the oxide semiconductor layer. A drain electrode of the metal nitride is disposed on the oxide semiconductor layer. A metal-nitride oxidation layer is formed on a surface of the source electrode and the drain electrode. A ratio of a thickness of the metal-nitride oxidation layer to a thickness of the drain electrode or the source electrode is equal to or less than 0.2.
