Abstract: A semiconductor device includes a mold layer defining a trench and a conductive structure disposed on the trench. The conductive structure includes a conductive layer and a liner, and the conductive layer includes upper and lower portions. The liner includes a base portion and a sidewall portion on the base portion, and the upper portion of the conductive layer is disposed at a level higher than the sidewall portion of the liner. The sidewall portion of the liner is interposed between the lower portion of the conductive layer and the mold layer, and a top surface of the base portion of the liner is in contact with a bottom surface of the lower portion of the conductive layer. A width of the sidewall portion of the liner may decrease as a level increases.
