Abstract:
In a matrix of conductive lines formed over a substrate comprising first and second series of conductive lines, one series being formed over another, an electrical connection method of establishing electrical communication between at least some of the lines and substrate node locations comprising:removing material of individual lines of an uppermost of the series of lines and exposing conductive material of the individual lines; after the removing of the material of the individual lines, forming insulative material over the substrate and the exposed conductive material; masking over the substrate and defining mask openings over substrate node locations with which electrical communication is desired; removing insulative material through the mask openings and other substrate material sufficient to expose both the conductive material of the individual lines which was previously exposed and the substrate node locations with which electrical communication is desired; and forming a plurality of conductive interconnects over the substrate, the interconnects establishing electrical communication between second exposed conductive material of the individual lines and individual respective substrate node locations.
