Abstract
A chip card module contains, in addition to conductor tracks and a chip carrier, one or more semiconductor chips and, if necessary, a stiffening frame. The semiconductor chip(s) and/or stiffening frame are attached with the aid of an adhesive, with which particles of a defined size are admixed as spacers. The adhesive in preferably a flexible adhesive, and the particles preferably are formed of a deformable material. The invention has the effect that the semiconductor chip(s) and/or stiffening frame are adhesively attached to the underlying surface at a defined, uniform distance. The flexible adhesive and the deformable particles adapt to deformations of the chip card module and thus prevent damage to the adhesively bonded mating surfaces.
