Claim Text:
1. A method of fabricating a component having electrodes for electrical interconnection with a circuit component or microelectronic element, comprising: removing material from a first surface of a substrate consisting essentially of a material having an effective CTE of less than 10 ppm/° C. to form a plurality of first openings extending from the first surface towards a second surface opposite the first surface, the first openings defining an undulating inner surface; forming a capacitor dielectric layer overlying the inner surface, the capacitor dielectric layer having an undulating first surface facing away from the inner surface; forming a first metal element overlying the first surface of the capacitor dielectric layer and extending into each of the first openings; removing material from the second surface of the substrate, such that a thickness of the substrate between the first and second surfaces is reduced; removing material of the substrate between adjacent ones of the plurality of first openings so as to expose an undulating second surface of the capacitor dielectric layer to form a plurality of second openings extending from the second surface towards the first surface; and forming a second metal element overlying the second surface of the capacitor dielectric layer and extending into each of the second openings.
