Patent ID: 8890318

Claim:
A contact structure, comprising: a patterned permanent antireflection coating formed directly on device formed on a substrate, said device having one or more contact pads; at least one patterned dielectric layer formed on the permanent antireflective coating, the at least one patterned dielectric layer and the permanent antireflective coating forming openings therein, the openings corresponding with locations of the contact pads; a barrier layer formed in the openings that includes a conductive catalyst; and conductive contact structures comprising carbon formed in the openings to make electrical contact with the contact pads such that the at least one patterned dielectric layer and the permanent antireflective coating each have a conductively filled region forming the contact structures, wherein the at least one patterned dielectric layer is a cured product of a dielectric composition comprising a polymer, copolymer, or a blend including at least two of any combination of polymers and/or copolymers; and wherein the openings in the at least patterned dielectric layer are formed by direct photo patterning of the dielectric composition prior to its curing.
