Abstract
An integrated circuit with capacitor structures includes a substrate and a plurality of vias extending from a front surface to a back surface of the substrate. A plurality of transistors is disposed at the front surface of the substrate and has first and second pluralities of electrodes. A patterned metal layer on the front surface of the semiconductor substrate provides first and second networks. The first network couples the first plurality of electrodes to a first via, and the second network couples the second plurality of electrodes to a second via. A dielectric layer separates first and second patterned metal layers on the back surface of the substrate. The first patterned metal layer includes a first metal plate coupled to the first via, and the second patterned metal layer includes a second metal plate coupled to the second via, forming a capacitor with the dielectric layer.
