Abstract:
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, fowling 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.

Claim (Index 1):
A semiconductor device comprising:\n a plurality of gate lines extending in a first direction in a substrate; an impurity region formed between the plurality of gate lines; a plurality of insulation film patterns on the plurality of gate lines, extending in the first direction; a conductive line contact formed between the plurality of insulation film patterns and is electrically connected to the impurity region; and a first mask pattern formed on the conductive line contact and the plurality of insulating film patterns, extending in a second direction that is different from the first direction, wherein the conductive line contact includes a landing pad formed by performing a photolithography process using the first mask pattern.
