Claim 7:
8. A capacitor, comprising:
a first metal layer in an opening in a first dielectric layer, the first metal layer having an uppermost surface at a same level as an uppermost surface of the first dielectric layer;
a ferroelectric layer on the first metal layer, the ferroelectric layer along and in contact with the uppermost surface of the first dielectric layer;
a second metal layer on the ferroelectric layer; and
a third metal layer on the second metal layer, wherein the thickness of the third metal layer is greater than the thickness of the second metal layer, wherein the ferroelectric layer extends laterally beyond the second metal layer and the third metal layer and laterally beyond the first metal layer, and wherein the ferroelectric layer has a bottommost surface below the uppermost surface of the first metal layer.
