Abstract:
1. An integrated circuit comprising: an integrated circuit region with a testing function; a Radio Frequency Identification (RFID) integrated circuit region including an RFID tag, the RFID tag being configured to store various administrative information including ID (identification) information and test results, wherein the information is stored in the RFID tag after the testing at a wafer level in response to a radio frequency signal request; an interface unit configured to perform the function of an interface between the integrated circuit region and the RFID integrated circuit region for storing the information in the RFID tag, a first antenna pad formed on the RFID integrated circuit region and connected to an RFID tag antenna; and a second antenna pad connected to the antenna and formed on the integrated circuit region, wherein the RFID tag includes: a memory block configured to receive an operation control signal to generate an internal control signal, store data in a nonvolatile ferroelectric capacitor in response to the internal control signal and output the stored data, wherein a chip confirmation code is stored in the nonvolatile ferroelectric capacitor of the RFID tag by the interface between the integrated circuit region and the RFID tag, wherein the RFID integrated circuit region includes the antenna formed using a wire, a lead frame and a stage, wherein the RFID integrated circuit region is formed over the stage.
