    摘要: The present invention provides a method of fabricating an interconnect structure in which a patternable low-k material replaces the need for utilizing a separate photoresist and a dielectric material. Specifically, this invention relates to a simplified method of fabricating single-damascene and dual-damascene low-k interconnect structures with at least one patternable low-k dielectric and at least one inorganic antireflective coating. In general terms, a method is provided that includes providing at least one patternable low-k material on a surface of an inorganic antireflective coating that is located atop a substrate, said inorganic antireflective coating is vapor deposited and comprises atoms of M, C and H wherein M is at least one of Si, Ge, B, Sn, Fe, Ta, Ti, Ni, Hf and La; forming at least one interconnect pattern within the at least one patternable low-k material; and curing the at least one patternable low-k material. The inventive method can be used to form dual-damascene interconnect structures as well as single-damascene interconnect structures.

    摘要: An organic dielectric material is patterned on a substrate in a process utilizing a patterned resist which contains a metalloid or metallic element at the time of pattern transfer to the organic dielectric layer. The organic dielectric layer is preferably patterned using an oxygen etching process, most preferably oxygen reactive ion etching. The process advantageously avoids the need for a hard mask.
