The present invention provides an interconnect structure in which a patternable low-k material is employed as an interconnect dielectric material. Specifically, this invention relates to single-damascene and dual-damascene low-k interconnect structures with at least one patternable low-k dielectric. In general terms, the interconnect structure includes at least one patterned and cured low-k dielectric material located on a surface of a substrate. The at least one cured and patterned low-k material has conductively filled regions embedded therein and typically, but not always, includes Si atoms bonded to cyclic rings via oxygen atoms. The present invention also provides a method of forming such interconnect structures in which no separate photoresist is employed in patterning the patterned low-k material.
