Patent ID: 7846852

Claim:
A manufacturing method for a capacitor embedded in an interposer comprising the steps of: providing a conductive stopper film and a capacitor on a base such that the conductive stopper film and capacitor are spaced apart from each other; forming a first wiring coupled to the conductive stopper film, a second wiring coupled to an anode of the capacitor, and a third wiring coupled to a cathode of the capacitor; forming an insulating layer covering the capacitor, the first wiring, the second wiring, and the third wiring; forming, on the insulating layer, a first electrode pad coupled to the first wiring, a second electrode pad coupled to the second wiring, and a third electrode pad coupled to the third wiring; forming potential applying sections respectively applying potentials from above the base to the anode and cathode; forming, in the base, a through hole extending from a back surface to the conductive stopper film; and forming, in the through hole, a conductor via coupled to the conductive stopper film.
