Patent ID: 8618663

Claim:
An interconnect structure comprising: at least one patterned and cured low-k dielectric material located on a surface of a patterned inorganic antireflective coating that is located atop a substrate, wherein said patterned inorganic antireflective coating is a permanent element of said interconnect structure and comprises a single layer of atoms of M, C and H wherein M is at least one of Ta, Ni, Hf and La, and said at least one patterned and cured low-k dielectric material and said patterned inorganic antireflective coating having conductively filled regions embedded therein, wherein said at least one patterned and cured low-k dielectric material comprises a functionalized polymer having one or more irradiation/acid-sensitive imageable groups, said functionalized polymer is selected from the group consisting of a carbosilane and an oxycarbosilane.
