<P>PROBLEM TO BE SOLVED: To effectively provide an inexpensive RFID (Radio Frequency IDentification) tag. <P>SOLUTION: This tag is equipped with; an interposer; an antenna and/or an inductor thereon, and an integrated circuit prepared on the interposer avoiding the antenna, etc., and having a bottom layer in contact with a surface of the interposer physically. This production method includes a step of forming a bottom layer of the integrated circuit on a surface of the interposer; a step of forming a following layer of the integrated circuit on the bottom layer of the integrated circuit; and a step of connecting a conductive layer to the interposer. A structure having conductivity may be formed from a functional layer attached to the interposer. This method includes; a step in which this device emits a detectable electromagnetic signal to generate sufficient current to reflect or modulate, or guides; a step of detecting the signal; and a step of processing information carried by the detectable electromagnetic signal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
