Patent ID: 8363418

Claim:
An interposer substrate, comprising: a first array of interposer interconnects in the interposer substrate, each interposer interconnect in the first array of interposer interconnects corresponding to interconnects in an array of processor interconnects; a second array of interposer interconnects in the interposer substrate, each interposer interconnect in the second array of the interposer interconnects corresponding to an array of circuit interconnects on a circuit substrate; and at least one conductive trace in the interposer substrate in connection with at least one interconnect in the first array of interposer interconnects, the conductive trace arranged to have a parallel portion parallel to the interposer substrate such that no electrical connection exists between the interconnect and a corresponding one of the interposer interconnects in the second array of interposer interconnects; and at least one peripheral circuit residing on the interposer substrate in electrical connection with the conductive trace.
