Via capacitor

摘要

A capacitor includes a first conductive layer disposed outwardly from a semiconductor substrate and comprising a first plate and a second plate. The capacitor also includes a first via layer disposed outwardly from the first conductive layer and comprising a first via coupled to the first plate and a second via coupled to the second plate. The first and second vias are separated by a dielectric and are operable to be charged with different potentials to establish a capacitance between the first and second vias. The capacitor further includes a second conductive layer disposed outwardly from the first via layer and comprising a third plate coupled to the first via and a fourth plate coupled to the second via.
