Patent ID: 7327555

Claim:
A capacitor structure comprising: a first electrode structure comprising a plurality of first conductive plates in parallel with one another, each first conductive plate comprising a plurality of first conductive bars, and each two adjacent first conductive bars being electrically coupled to each other by at least a first conductive via; a second electrode structure comprising a plurality of second conductive plates in parallel with one another, the second conductive plates being disposed in alternation with the first conductive plates, each second conductive plate comprising a plurality of second conductive bars, and each two adjacent second conductive bars being electrically coupled to each other by at least a second conductive via; and a dielectric layer disposed between the first conductive plates and the second conductive plates; wherein the horizontal cross-sectional area of the first conductive via is substantially equal to the horizontal cross-sectional area of each first conductive bar adjacent to the first conductive via, and voltages applied to the first electrode structure and the second electrode structure are not equal.
