Patent ID: 8637395

Claim:
A method of forming a semiconductor structure comprising: providing at least one photo-patternable low-k (PPLK) material an upper surface of a substrate; forming at least one interconnect pattern into the at least one PPLK material providing at least one patterned PPLK material, wherein said forming the at least one interconnect pattern is performed without utilizing a separate photoresist; transferring the at least one interconnect pattern from the at least one patterned PPLK material into a portion of said substrate; and curing the at least one patterned PPLK material, wherein said curing induces shrinkage of the at least one patterned PPLK material forming a patterned and cured PPLK material that has a bottom sidewall profile at a bottom portion of the patterned and cured PPLK material that exhibits a change in curvature and an upper sidewall profile at an upper portion of the patterned and cured PPLK material that is substantially straight, wherein said patterned and cured PPLK material remains as a permanent interconnect dielectric material.
