ABSTRACT:
A technique is provided for correcting miswiring on a chip for test purposes. When an IC chip has been formed during a prototype operation, often I/O wiring is found to be deficient. This deficiency can be corrected by providing an interposer which has pads on one surface corresponding to the pads on the IC chip and pads on the opposite surface of the interposer corresponding to the desired output connections. Vias are formed through the interposer and the miswired connections on the chip surface are wired through the vias to the proper connections for the output of the chip as well as the proper connections on the chip being wired to the proper connections for the output connection on the opposite surface of the interposer.
