Abstract: A semiconductor device includes a substrate with lower structures, an insulation layer covering the lower structures on the substrate, a contact hole through the insulation layer partially exposing the substrate, and a contact structure contacting the substrate through the contact hole, the contact structure including a barrier pattern having an upper barrier on an upper portion of a sidewall of the contact hole, and a lower barrier filling a lower portion of the contact hole, and a conductive contact pattern filling an upper portion of the contact hole defined by the upper barrier and the lower barrier.
