Patent ID: 8362589

Claim:
A capacitor in an integrated circuit (“IC”) comprising: a distribution grid, associated with a first node of the capacitor, formed in a first patterned metal layer of a plurality of metal layers of the integrated circuit, the plurality of metal layers comprising successive metal layers separated by dielectric layers; a first vertical conductive filament connected to and extending away from the distribution grid along a first axis in a first direction, wherein the first vertical conductive filament is electrically connected to the first node only through the distribution grid; a second vertical conductive filament connected to and extending away from the distribution grid along the first axis in a second direction opposite the first direction, wherein the second vertical conductive filament is electrically connected to the first node only through the distribution grid; a first grid plate, associated with a second node of the capacitor, formed in a second patterned metal layer which is a next successive metal layer adjacent to the first patterned metal layer, the first grid plate surrounding the first vertical conductive filament in the second patterned metal layer; and a second grid plate, associated with the second node of the capacitor, formed in a third patterned metal layer which is a next successive metal layer adjacent to the second patterned metal layer, the second patterned metal layer disposed between the first patterned metal layer and the third patterned metal layer, the second grid plate surrounding the first vertical conductive filament in the third patterned metal layer.
