Abstract

A semiconductor device includes an interlayer insulating layer disposed on a substrate, the interlayer insulating layer comprising an opening exposing the substrate, a barrier layer pattern disposed within the opening, and a conductive pattern disposed on the barrier layer pattern, the conductive pattern having an oxidized portion extending out of the opening and a non-oxidized portion within the opening, wherein a width of the conductive pattern is determined by a thickness of the barrier layer pattern.
