Abstract:
1. An integrated circuit (IC) card comprising: a conductive circuit pattern disposed on an insulation film, the conductive circuit pattern including a loop antenna portion, a connection portion, and an attachment portion, the connection portion and the attachment portion being laterally displaced from each other on the insulation film; a semiconductor chip including a chip bump, the semiconductor chip mounted on the connection portion of the conductive circuit pattern through the chip bump and thereby enabling an electrical connection between the semiconductor chip and the connection portion of the conductive circuit pattern; at least one dielectric layer including a through hole at a location corresponding to the attachment portion of the conductive circuit pattern, the dielectric layer attached to the conductive circuit pattern; and an external contact pad received in the through hole of the dielectric layer, the external contact pad having terminals formed in an upper surface and an lower surface of a substrate, the terminals of the upper surface being electrically connected to the corresponding terminals of the lower surface, the terminals on the lower surface being electrically connected to the attachment portion of the conductive circuit pattern, and thereby enabling an electrical connection between the semiconductor chip, the terminals of the external contact pad, and the loop antenna portion of the conductive circuit pattern.
