发明名称 Airgap-containing interconnect structure with patternable low-k material and method of fabricating
摘要 The present invention provides a method of fabricating an airgap-containing 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 airgap-containing low-k interconnect structures with at least one patternable low-k dielectric and at least one inorganic antireflective coating.
