Abstract: A semiconductor device includes a gate insulating layer disposed on a substrate, a first work function tuning layer disposed on the gate insulating layer, a lower barrier conductive layer on and in contact with the first work function tuning layer, and an upper barrier conductive layer on and in contact with the lower barrier conductive layer. The upper barrier conductive layer and the lower barrier conductive layer include a material in common, e.g., they may each include a titanium nitride (TiN) layer.
