Patent ID: 8772941

Claim:
An electrical circuit structure, comprising: at least two generally parallel conductor structures; a solid dielectric material generally interposed between said at least two generally parallel conductor structures; a pinching dielectric material, separate and distinct from said solid dielectric material, wherein said pinching dielectric material is homogeneous and is in contact with said solid dielectric material; a plurality of relatively low dielectric constant (low-k) volumes located within said solid dielectric material between said at least two generally parallel conductor structures and surrounded and sealed by a composition of said pinching dielectric material and a barrier; wherein said relatively low-k volumes are structurally configured to reduce parasitic capacitance between said at least two generally parallel conductor structures as compared to an otherwise comparable circuit not including said relatively low-k volumes wherein said relatively low dielectric constant (low-k) volumes contain substantially gaseous material; wherein said solid dielectric material generally defines a dielectric material stack; and said at least two generally parallel conductor structures comprise metallized dual-damascened via line structures in a same plane as said dielectric material stack.
