Patent ID: 7683413

Claim:
A container capacitor for a semiconductor device comprising: a first capacitor top plate layer having a generally cylindrical shape comprising an internal surface and an external surface; a first cell dielectric layer having a generally cylindrical shape comprising an internal surface and an external surface, wherein the external surface of the first cell dielectric layer contacts the internal surface of the first capacitor top plate layer; a first capacitor bottom plate layer having a generally cylindrical shape comprising an internal surface and an external surface, wherein the external surface of the first capacitor bottom plate layer contacts the internal surface of the first cell dielectric layer; a second capacitor bottom plate layer having a generally cylindrical shape comprising an internal surface and an external surface, wherein the external surface of the second capacitor bottom plate layer contacts the internal surface of the first capacitor bottom plate layer; a second cell dielectric layer having a generally cylindrical shape comprising an internal surface and an external surface, wherein the external surface of the second cell dielectric layer contacts the internal surface of the second capacitor bottom plate layer; and a second capacitor top plate layer having a generally cylindrical shape comprising an internal surface and an external surface, wherein the external surface of the second capacitor top plate layer contacts the internal surface of the second cell dielectric layer.
