Abstract:
1. An interlevel dielectric structure comprising: a single first dielectric layer situated on a semiconductor substrate, said single first dielectric layer having an upper surface; a plurality of lines of a two-layer conductive material extending along said upper surface of said single first dielectric layer; wherein: a single second dielectric layer above both said plurality of lines and said single first dielectric layer, said single second dielectric layer having a lower surface in contact with the upper surface of each line of said plurality of lines; and a single dielectric material situated in said space between adjacent lines of said plurality of lines, said single dielectric material not extending over the upper surface of each line of said plurality of lines, an upper surface of said single dielectric material being higher than the upper surface of each line of said plurality of lines, and a lower surface of said single dielectric material being lower than the lower surface of each line of said plurality of lines.
