Abstract:
1. An integrated circuit device comprising: an integrated circuit substrate; an insulation layer on the integrated circuit substrate including a first portion adjacent the substrate and a second portion protruding therefrom remote from the substrate, wherein the second portion is narrower than the first portion; a conductive line on the insulation layer, the conductive line including a bottom on the protruding second portion of the insulation layer, a top remote from the insulation layer and first and second sidewalls therebetween; and a spacer that extends along the first and second sidewalls of the conductive line and along at least a portion of the bottom between the conductive line and the first portion of the insulation layer adjacent the second portion of the insulation layer such that the spacer is bifurcated by the protruding second portion of the insulation layer.
