A paper-like RFID tag is fabricated by bonding bumps of an RFID chip (1) to an antenna (2) to connect the chip (1) to the antenna (2), the antenna (3) being formed by a metal foil bonded onto a base film or a base tape, providing a protecting material (4) around the RFID chip (1) so that an upper surface (4a) thereof becomes higher than that of the RFID chip (1), to constitute an RFID thread, and inlaying the RFID thread in between first and second paper layers (5a, 5b) to afford a paper-like structure.
The thickness of the paper-like RFID tag fabricated as above is 0.1 mm or less. Further, the paper-like RFID tag is of high quality and has a surface smoothness almost equal to that of the ordinary type of paper, permitting a long-distance communication. |
