Patent ID: 7633112

Claim:
A metal-insulator-metal capacitor, comprising: a first electrode in a first wiring level; a second electrode above the first wiring level, the second electrode extending into a first portion of the first electrode and extending toward a second portion of the first electrode, wherein the second portion of the first electrode is in a first dielectric layer and the first portion of the first electrode is in a second dielectric layer; a plurality of third portions of the first electrode extending toward the second electrode; a dielectric film separating the first electrode from the second electrode; and a via in the second dielectric layer interconnecting a wiring line of the first wiring level to an other wiring line of an other wiring level, wherein the first portion of the first electrode surrounds the second electrode and the plurality of third portions of the first electrode, and wherein a first height of the first portion of the first electrode from the second portion of the first electrode is greater than a second height of the via from the other wiring line to the wiring line of the first wiring level.
