ABSTRACT:
The present invention provides a RFID device comprising a radio frequency identification (RFID) transceiver and antenna element co-located with a semiconductor device, a method for making same and a method of using the RFID device of the present invention to locate, track and identify semiconductor devices and the devices they reside in. One embodiment of the RFID device of the present invention comprises a radio frequency identification (RFID) transceiver embedded within packaging of a semiconductor device. A second embodiment of the RFID device of the present invention comprises a radio frequency identification (RFID) transceiver as a separate circuit block within the semiconductor device. A third embodiment of the RFID device of the present invention comprises a radio frequency identification (RFID) transceiver as a separate independent circuit on top of the semiconductor device, System on Chip (SoC). These RFIDs can also be nested within an enclosure, or combined to increase the address length of the RFID.
