Card mounted with circuit chip and circuit chip module

摘要

A circuit chip mounted card has a processing-circuit layer 106 in which is constructed a processing unit including a non-volatile memory, a modulation/demodulation circuit and a capacitor for providing a process associated with communication. In the processing-circuit layer is also constructed a coil 44 of a looped metal wire. Communicating function is completely provided only by a single IC chip 104 with the function of the processing unit and that of an antenna integrated therewith. Thus IC chip 104 does not require external wiring and will thus not suffer from an accidentally cut-off wire or the like. It is also dispensed with an operation to connect wires so that the card can extremely readily be fabricated. Thus a circuit chip mounted card can be obtained which is highly reliable and reduces the cost for manufacturing the same.
