Abstract
A decoupling capacitor is provided for a semiconductor device and may include a first low dielectric insulator layer and a low resistance conductor formed into at least two interdigitized patterns on the surface of the first low dielectric insulator in a single interconnect plane. A high dielectric constant material may be provided between the two patterns. A circuit for testing a plurality of these capacitors is also provided which includes a charge monitoring circuit, a coupling circuit and a control circuit.
