Patent ID: 8017441

Claim:
A method for manufacturing an IC tag inlet including: a semiconductor chip having formed an integrated circuit and a first electrode on its main surface and a second electrode on its back surface; a first antenna connected to one of the first and second electrodes; a second antenna connected to the other of the first and second electrodes; and a support resin covering the semiconductor chip and sandwiched by the first and second antennas, and the method comprising the steps of: (a) depositing a support resin on a main surface of a semiconductor wafer having an integrated circuit and a first electrode formed on the main surface, and a second electrode formed on a back surface; (b) attaching the back surface of the semiconductor wafer to a dicing tape; (c) dicing the semiconductor wafer attached to the dicing tape to singulate it into a plurality of semiconductor chips whose main surfaces are covered with the support resin; (d) heating and melting the support resin covering respective main surfaces of the plurality of semiconductor chips to cover each of whole surfaces of the plurality of semiconductor chips by the support resin; (e) sandwiching each of the plurality of semiconductor chips covered by the support resin between the first antenna and the second antenna after the step (d); and (f) melting and pressing the support resin to electrically connect the first electrode of each of the plurality of semiconductor chips to one of the first and second antennas, and electrically connect the second electrode to the other side of the first and second antennas after the step (e).
