Patent ID: 7791205

Claim:
An interposer for use in a semiconductor assembly, comprising: an upper surface; a perimeter wall substantially encircling the upper surface to form a recess, the recess comprising at least a first set of alternate upper electrical contact pads located therein, the at least a first set of alternate upper electrical contact pads comprising at least a first upper electrical contact pad and at least a second upper electrical contact pad, the at least a first set of alternate upper electrical contact pads positioned and arranged to lie within a lateral periphery of a semiconductor die disposed in the recess and to correspond to an arrangement of bond pads on the semiconductor die; and a lower surface having at least a first lower electrical connection pad located thereon, the at least a first lower electrical connection pad electrically connected to the at least a first upper electrical contact pad and the at least a second upper electrical contact pad in the absence of a semiconductor die within the recess, wherein the electrical connection is made through at least one conductive pathway carried by the interposer.
