Patent ID: 8408473

Claim:
A method for production of an RFID transponder product, comprising the steps of: a. creating a non-intersecting coil-shaped antenna structure with a chip terminal and a bridge terminal as well as a connecting structure with a chip terminal and a bridge terminal on a non-conductive carrier layer with a continuous surface, b. contacting a naked chip to the chip terminals of the antenna structure and the chip terminal of the connecting structure in flip-chip technology, c. creating an embedding opening matching size and location of the naked chip as well as two contacting openings matching location of the bridge terminals in at least one non-conducting compensation layer, d. creating a bridge structure with at least two connecting terminals on a non-conducting cover layer, e. positioning the compensation layer over the carrier layer such that the naked chip is arranged in the embedding opening of the compensation layer and the contacting openings are arranged over the bridge terminals of the antenna structure and the connecting structure and positioning the cover layer over the compensation layer such that the connecting terminals are arranged over the contacting openings of the compensation layer, and f. connecting the carrier layer, the compensation layer, and the cover layer with each other by laminating or adhering.
