    摘要: A method for manufacturing a semiconductor device includes forming features of a first mold pattern on a substrate including a first region and a second region, and forming a first insulation layer covering the first mold pattern from the first region to the second region. The method further includes forming a photoresist pattern on the first insulation layer in the second region, forming a second insulation layer covering the first insulation layer in the first region and the photoresist pattern in the second region from the first region to the second region, etching the second insulation layer, removing the photoresist pattern, and forming a first double patterning technology pattern having a first width in the first region and a second DPT pattern having a second width in the second region, wherein the second width is different from the first width.

    摘要: Methods for manufacturing a semiconductor device include forming a gate line extending in a first direction in a substrate, and an impurity region on a side surface of the gate line, forming an insulating film pattern on the substrate, the insulating film pattern extending in the first direction and comprising a first through-hole that is configured to expose the impurity region, forming a barrier metal layer on the first through-hole, forming a conductive line contact that fills the first through-hole and that is electrically connected to the impurity region, forming a first mask pattern on the conductive line contact and the insulating film pattern, the first mask pattern extending in a second direction that is different from the first direction and the first mask pattern comprising a first opening, and removing corners of the barrier metal layer by partially etching the barrier metal layer.
