Abstract:
A semiconductor processing method of forming a conductive projection comprising:forming a pair of spaced-apart, insulated conductive lines over a substrate, the conductive lines defining a node location therebetween with which electrical communication is desired;forming insulative material over the node location and between the conductive lines;forming an opening through the insulative material and between the lines to proximate the node location;forming conductive material within the opening over the node location, the conductive material comprising an outer portion received elevationally outward of the insulated conductive lines, the conductive material having side surfaces which project away from the node location and terminate proximate an upper surface, the side surfaces and upper surface defining at least one corner region, the side surfaces defining a width of the outer portion of the conductive material within the opening; andbeveling the corner region effective to reduce the width of the outer portion of the conductive material above the conductive lines and etching at least some of the conductive material away from an entirety of the upper surface.
