Claim Text:
1. A semiconductor device, comprising: a substrate having a plurality of fin field-effect transistors (FinFETs) and a plurality of fin capacitors, wherein each of said plurality of fin capacitors further comprises: a plurality of silicon fins extending from and above a top surface of the substrate, wherein the plurality of fins includes two adjacent silicon fins each having a first sidewall and an opposing second sidewall, the first and second sidewall extending from and being perpendicular to the top surface of the substrate; at least one electrical conductor between and parallel with the two adjacent silicon fins, wherein a top surface of the plurality of silicon fins and a top surface of the at least one electrical conductor are coplanar; a first insulating material between the first sidewall of a first silicon fin of the two adjacent silicon fins and the at least one electrical conductor and also between the first sidewall of a second silicon fin of the two adjacent silicon fins and the at least one electrical conductor, wherein the first insulating material forms an interface with the first sidewall of each of the first and second silicon fins; and a second insulating material disposed over the top surface of the substrate, under the first insulating material and the at least one electrical conductor, the second insulating material extending from an interface with the first sidewall of the first silicon fin to an interface with the first sidewall of the second silicon fin.
