Chip card

摘要

In chip cards which interact with a further stationary circuit arrangement via contactless electromagnetic power and/or signal transmission and which contain at least one integrated circuit and one antenna coil connected to this integrated circuit, this coil has previously been mounted separately next to the integrated circuit on a carrier body and was connected to the integrated circuit via bonded connections. This requires additional work cycles. The coil is integrated together with the integrated circuit, preferably applied to the semiconductor body of the integrated circuit, for example in such a manner that the turns of the antenna coil extend concentrically around the active area of the semiconductor body. <IMAGE>
