Patent ID: 8502340

Claim:
A component having electrodes for electrical interconnection with a circuit component or microelectronic element, comprising: a substrate consisting essentially of a material having a coefficient of thermal expansion of less than 10 ppm/° C., the substrate having a first surface, a second surface opposite the first surface, and an opening extending downwardly from the first surface; and a first capacitor formed in contact with the substrate, including: a first pair of electrically conductive plates being first and second plates and a second pair of electrically conductive plates being third and fourth plates, each plate extending along an inner surface of the opening, wherein the first plate overlies the inner surface, the third plate overlies the first plate and is separated therefrom by a first capacitor dielectric layer, the second plate overlies the third plate and is separated therefrom by a second dielectric layer, and the fourth plate overlies the second plate and is separated therefrom by a third capacitor dielectric layer; first and second electrodes, the first electrode exposed at the first surface at a first location and electrically connected to the first pair of plates, the second electrode exposed at one of the first and second surfaces at a second location spaced apart from the first location and electrically connected to the second pair of plates; and third and fourth electrodes exposed at respective third and fourth spaced apart locations, the third electrode electrically connected to the first pair of plates and the fourth electrode electrically connected to the second pair of plates.
