Claim Text:
1. An interconnect structure for an integrated circuit, the interconnect structure comprising: a first layer of the interconnect structure disposed above a substrate, the first layer comprising a first grating of alternating metal lines and dielectric lines in a first direction, wherein the dielectric lines have an uppermost surface higher than an uppermost surface of the metal lines; and a second layer of the interconnect structure disposed above the first layer of the interconnect structure, the second layer comprising a second grating of alternating metal lines and dielectric lines in a second direction, perpendicular to the first direction, wherein the dielectric lines have a lowermost surface lower than a lowermost surface of the metal lines of the second grating, wherein the dielectric lines of the second grating overlap and contact, but are distinct from, the dielectric lines of the first grating; and first and second dielectric regions disposed between the metal lines of the first grating and the metal lines of the second grating, and in a same plane as upper portions of the dielectric lines of the first grating and lower portions of the dielectric lines of the second grating, the first dielectric region comprising a first cross-linked photolyzable material, and the second dielectric region comprising a second, different, cross-linked photolyzable material.
