Patent ID: 7745924

Claim:
A capacitor embedded in an interposer comprising: a base; a conductor via embedded in said base and extending through said base from an upper surface to a lower surface; a capacitor provided on said base; a first wiring coupled to said conductor via; a second wiring coupled to an anode of said capacitor; a third wiring coupled to a cathode of said capacitor; an insulating layer covering said capacitor, said first wiring, said second wiring, and said third wiring; a first electrode pad on said insulating layer and coupled to said first wiring; a second electrode pad on said insulating layer and coupled to said second wiring; a third electrode pad on said insulating layer and coupled to said third wiring; a fourth wiring covered by said insulating layer; a fourth electrode pad on said insulating layer and coupled to one end of said fourth wiring; and a fifth electrode pad coupled to the other end of said fourth wiring to which one end of a wire is bonded, wherein potentials are respectively applied from above said base to said anode and cathode.
