Patent ID: 7279366

Claim:
A method for constructing a semiconductor assembly with a common footprint using a semiconductor die selected from an equivalent set of semiconductor dice having different bond pad arrangements, the method comprising: forming an interposer comprising an upper surface, a lower surface, a perimeter wall substantially encircling the upper surface to form a recess, at least one alternative set of upper electrical contact pads disposed in the recess, and at least a first lower electrical connection disposed on the lower surface and in direct electrical communication with each upper electrical contact pad of the at least one alternative set of upper electrical contact pads through at least one conductive pathway carried by the interposer; selecting a semiconductor die from an equivalent set of semiconductor dice having different bond pad arrangements, such that an equivalent bond pad on the semiconductor die will be adjacent to, and in electrical communication with one upper electrical contact pad of the at least one alternative set of upper electrical contact pads upon installation; and attaching the selected semiconductor die within the recess, such that the equivalent bond pad on the semiconductor die is in electrical communication with the at least a first lower electrical connection through the one upper electrical contact pad of the at least one alternative set of upper electrical contact pads in electrical communication therewith.
