Abstract
A capacitor device may include a first electrode, a second electrode, a third electrode, a first dielectric layer, and a second dielectric layer. The first electrode may be coupled with a first terminal of the capacitor device. The second electrode is under the first electrode and may be coupled with a second terminal of the capacitor device. The second electrode may be electrically isolated from the first electrode. The third electrode is under the first electrode and the second electrode and may be electrically isolated from the second electrode and electrically coupled with the first electrode. The first dielectric layer has a first dielectric constant and may be sandwiched between the first electrode and the second electrode. The second dielectric layer may have a second dielectric constant and may be sandwiched between the second electrode and the third electrode. In one embodiment, the second dielectric constant is at least five times larger than the first dielectric constant.
