Abstract:
A variable resistance memory device includes a metal interconnection layer on a substrate, an interlayer insulating layer on the metal interconnection layer and defining a contact hole for exposing a portion of the metal interconnection layer, a barrier metal layer including a plurality of sub-barrier metal layers inside the contact hole, a plug metal layer on the barrier metal layer and burying the contact hole, and a variable resistance structure on the barrier metal layer and the plug metal layer.

Claim (Index 10):
A variable resistance memory device comprising:\n a substrate; a metal interconnection layer on the substrate; an interlayer insulating layer on the metal interconnection layer, the interlayer insulating layer defining a contact hole for exposing a portion of the metal interconnection layer; a first barrier metal layer on the metal interconnection layer, the first barrier metal layer covering a bottom of the contact hole and covering an inner wall of the contact hole; a second barrier metal layer on the first barrier metal layer; a plug metal layer on the second barrier metal layer,\n the plug metal layer burying the contact hole, \n the plug metal layer, the first barrier metal layer, and the second barrier metal layer forming a contact plug having a first width; and \n a variable resistance structure on the first barrier metal layer, the second barrier metal layer, and the plug metal layer,\n the variable resistance structure having a second width.
