Summary:Technologies suitable for on-wafer testing in the ubiquitous computing era are disclosed. Among the inventive features disclosed are: 1) clustering of wafer test probe landing area sites for parallel test sequencing; 2) on wafer test wiring that runs along the wafer's scribe regions; 3) on-wafer test wiring that can be scribed and yet thwart the spread of contamination into the product die; 4) an RFID tag design that allows for on-wafer testing without imposing substantial semiconductor surface area penalty; 5) an RFID tag design that includes built-in self test (BIST) circuitry for the RFID tag's non-volatile memory.
