Patent ID: 7268383

Claim:
A capacitor comprising: a first electrode formed in a semiconductor substrate, the first electrode including a first via and a first line, the first line being connected to the first via, the first electrode being in electrical contact with a first region of the semiconductor substrate; a second electrode formed in the semiconductor substrate, the second electrode including a second via and a second line, the second line being connected to the second via, the second electrode being in electrical contact with a second region of the semiconductor substrate; a high-k dielectric disposed between the first line and the second line and between the first via and the second via, wherein the first line and the first via form a first vertical plate of the capacitor, and the second line and the second via form a second vertical plate of the capacitor; and a first dielectric disposed on an opposing side of the first line and the first via from the high-k dielectric, the first dielectric having a lower dielectric constant than the high-k dielectric.
