Abstract
A capacitor structure having a complete terminal shield is provided. The capacitor structure may include a first conductive segment with a first set of conductive fingers and a second segment structure with a second set of conductive fingers. The second set of conductive fingers may be spatially interleaved with the first set of conductive fingers in the first conductive structure. The first conductive segment may receive a first voltage, whereas the second conductive segment may receive a second voltage that is different than the first voltage. The capacitor structure further includes a conductive shielding structure that is connected to the first conductive segment. The conductive shielding structure may laterally surround the second conductive segment from at least three sides. An additional conductive shielding structure that connects to the first and second conductive segments is formed directly above the first and second conductive segments.
