Abstract
A capacitor device selectively combines MOM, MIM and varactor regions in the same layout area of an IC. Two or more types of capacitor regions arranged vertically on a substrate to form the capacitor device. This increase the capacitance per unit of the capacitor device, without occupying an extra layout area.
