Patent ID: 7531443

Claim:
A method for fabricating a semiconductor component comprising: providing a semiconductor substrate comprising a circuit side, a back side, a plurality of integrated circuits on the circuit side, and a plurality of substrate contacts on the circuit side in electrical communication with the integrated circuits; forming a plurality of vias in the substrate extending from the back side to the substrate contacts; forming a conductive layer in the vias in electrical contact with the substrate contacts and on the back side of the semiconductor substrate; forming the conductive layer in the vias into a plurality of through interconnects in electrical contact with the substrate contacts; and forming the conductive layer on the back side of the semiconductor substrate into a plurality of conductors in electrical contact with the through interconnects; wherein the forming the conductive layer step, the forming the through interconnects step, and the forming the conductors step comprise a same metal deposition step performed from the back side of the semiconductor substrate.
