INTERCONNECT STRUCTURE AND METHOD OF FABRICATING |
摘要 |
An interconnect structure is provided which comprises a semiconductor substrate; a patterned and cured photoresist wherein the photoresist contains a low k dielectric substitutent and contains a fortification layer on its top and sidewall surfaces forming vias or trenches; and a conductive fill material in the vias or trenches. Also provided is a method for fabricating an interconnect structure which comprises depositing a photoresist onto a semiconductor substrate, wherein the photoresist contains a low k dielectric constituent; imagewise exposing the photoresist to actinic radiation; then forming a pattern of vias or trenches in the photoresist; surface fortifying the pattern of vias or trenches proving a fortification layer on the top and sidewalls of the vias or trenches; curing the pattern of vias or trenches thereby converting the photoresist into a dielectric; and filling the vias and trenches with a conductive fill material.
