Abstract
A thin film capacitor having a top, middle and bottom plate forming two capacitors in series in which the middle plate is a plurality of isolated plates thereby forming a structure of a plurality of two capacitors in series which are all connected in parallel. The capacitor may be integrated into an electronic substrate. The capacitor may be formed by depositing films of the metal conductors and dielectrics and may be formed as an integral part of a semiconductor chip or interconnect substrate.
