Patent ID: 7821051

Claim:
A structure, comprising: a dielectric layer on a top surface of a semiconductor substrate, said dielectric layer having a top surface and a bottom surface; a trench in said dielectric layer, said trench extending from said top surface to said bottom surface of said dielectric layer; a first plate of a MIM capacitor comprising a conformal conductive liner having a top surface and a bottom surface, said bottom surface of said conformal conductive liner in direct physical contact with all sidewalls and extending along a bottom of said trench, said bottom of said trench coplanar with said bottom surface of said dielectric layer; a conformal insulating layer formed on said top surface of said conformal conductive liner; a second plate of said MIM capacitor comprising a single layer of a core conductor in direct physical contact with said insulating layer, said core conductor filling spaces in said trench not filled by said conformal conductive liner and said insulating layer; a conductive plate under said dielectric layer and in direct physical and electrical contact with said conformal conductive liner, a less than whole portion of a top surface of said conductive plate coextensive with a less than whole portion of a bottom surface of said conductive liner; and a conductive contact formed in said dielectric layer and extending from said top surface of said dielectric layer to said bottom surface of said dielectric layer, said conductive contact in direct physical and electrical contact with another less than whole portion of said top surface of said conductive plate.
