Abstract

A semifinished product for an electronic module includes an integrated circuit and a coil electrically connected with the circuit, the coil being disposed between two carrier layers and the integrated circuit being disposed in a specially provided cavity in the two carrier layers. To achieve plane surfaces of the semifinished product, the remaining cavity between the carrier layers and the integrated circuit is filled with a filling material in such a way that plane surfaces of the semifinished product result in the area of the cavity which are flush with the surfaces of the carrier layers.
