Abstract
Abstract A capacitor structure in a hybrid multilayer circuit having a plurality of insulating layers, the capacitor structure including a dielectric via fill in a via formed in one of the insulating layers, a first conductive element overlying the dielectric via fill, and a second conductive element underlying said dielectric via fill. Each of the first and conductive elements comprises a conductive via fill or a conductive trace.
