Abstract:
The invention concerns a chip card module (1) which comprises a chip carrier (2), electrically conductive contact surfaces (3) and a semiconductor chip which is disposed in an SMT housing (4), contact with the contact surfaces (3) being established via the connection legs (5) which are guided outwards out of the housing (4). The chip card modules according to the invention can be easily produced and have a low component height. In addition, the semiconductor chip is well protected against mechanical damage. The invention also concerns a chip card (7) comprising the claimed chip card module (1).
Abstract:
The invention concerns a chip card with a contact zone in the region of which an electrically conductive and possibly tinted varnish is applied. In this way, the contact zone itself can also be used as a data carrier if the conductive varnish reproduces the logo of the chip card manufacturer, for example. The disadvantage of chip cards of the type in question is that the varnishing of the contact zones is subject to a high degree of wear owing to friction. In addition, the electrically conductive particles frequently oxidize, and so the resistance when the contact zone is accessed increases such that satisfactory functioning of the chip card is no longer ensured. The object of the invention is therefore to produce a chip card of the type in question which functions reliably for a long time, and propose a method of producing the same. To that end, the varnish is based on an intrinsically conductive plastics material.
Abstract:
The invention concerns a system for protecting a semiconductor chip (1) with a covering (4) against copying, the system comprising an oscillating circuit which is capable of resonance and whose elements are located on the chip surface (3) and inside the covering (4), and an evaluation circuit connected thereto. The circuit deactivates the semiconductor chip when the oscillating circuit is brought out of resonance. This off-resonance adjustment of the oscillating circuit occurs when the covering (4), which acts as a dielectric of the capacitor, is removed. It is impossible to operate the semiconductor chip (1) for copying or analysis purposes once its covering (4) has been removed.

This invention concerns a combination chip module for transmission of electrical signals or data with or without contact to an external read-write station with an elongation-resistant, electrically insulated substrate (2), on or in which one or more integrated semiconductor circuits are arranged. The circuits are connected, via connecting terminals (6), a) to one or more couplers of an interface circuit which is either separate orin integrated form and provided in the chip module (1), which interface circuit enables contactless bidirectional data communication between the chip module (1) and the external read-write station, and b) to electrically conducting contact surfaces (8) provided on one side of the substrate (2), which contact surfaces (8) enable bidirectional data communication with contact, between the chip module (1) and the external read-write station. The one or more couplers have metal printed conductors which are also formed on the side of the substrate (2) facing the contact surfaces (8).

In addition, a thin insulating film (10) of electrically insulating material with a plurality of bonding holes (9) is provided between the electrically conducting contact layer (2) and semiconductor chip (7). The arrangement, shape and number of the holes and their allocation to a particular contact element (4) of the contact layer is such that with any position and surface content of the secured semiconductor chip (7), contact can be ensured between the chip contacts via the bonding wires (6) with an appropriate contact element (4) of the contact layer (2).
