Abstract:
A semiconductor device comprising:a substrate;an insulating layer formed on the substrate; andan interconnect structure including:a first conductive pattern formed on the insulating layer, the conductive pattern including at least two conductive lines adjacent one another;a first dielectric material selected from at least one of: polyimides, Teflon, and aerogels and formed over the conductive pattern, the first dielectric material filling a space between the at least two conductive lines;at least one plug formed in the first dielectric material;a second conductive pattern formed over the first dielectric material and the at least one plug;wherein at least a portion of the first and the second conductive patterns associated with the interconnect structure is coaxial in nature; anda second dielectric material formed over the interconnect structure, the second dielectric material having a dielectric constant less than about 3.0.
