Abstract
Externally formed connections are made to a wafer scale integration (WSI) type of semiconductor device to accomplish wafer level defect avoidance and includes the utilization of a relatively small external shorting block or patch circuit for implementing predetermined shorting connections, such as jumpers, on a diode decoder circuit on the wafer to program an address of a defective primary site into a register associated with a predetermined spare site for substituting the spare site for a defective primary site when power is applied to a fully processed WSI wafer having (n+r) sites including (n) primary sites and (r) spare sites and where n primary sites are required to perform a predetermined circuit function.
