Definitions
- the invention relates to a chip card module comprising a carrier which has contact areas, a semiconductor chip being arranged opposite the contact areas on the carrier, according to patent claim 1.
- Chip cards have been known for a long time and are increasingly used, for example, as telephone cards, identification cards or the like. There are standards that define the dimensions and technical details of such chip cards. This standard is, for example, ISO7810 and IS07816.
- the chip cards are currently divided into three categories: contactless chip cards, contact-based chip cards and so-called combination cards. Both the contact-based chip cards and the combination cards have a contact zone which provides contacts in accordance with the standards mentioned above. These are connected to a circuit integrated in the chip card. The arrangement of these contact areas on the chip card is clearly defined by the standards mentioned.
- the contact zones of the card contacts currently consist of a suitable metallic surface, which are made of Au, NiPdAg or similar materials, for example. The individual contact areas are separated from one another by isolating them in separation channels.
- a method of checking the authenticity of documents in the form of chip cards is known from WO97 / 33252, for example. This is achieved in that from a basic mass Foreign objects stored in the chip card, the physical properties of which differ from those of the basic mass and are randomly distributed within the basic mass, existing documents are first scanned for at least one detector for foreign objects in at least one scanning track selected by a random generator. Thereafter, the output values of the detector are written into a register that is blocked after initialization and is provided in the chip of the chip card, the stored content of which is neither legible nor manipulable from the outside.
- the document prepared in this way is used, its foreign body information is continuously read by a detector and temporarily stored in a further register in the chip and compared internally with the data about the foreign body pattern stored in the first register. If the comparison shows a match, the document is released.
- a disadvantage of this procedure is that the identification, which takes place from the assignment of the chip to the card, takes place at a relatively late point in time.
- the invention is therefore based on the object of providing a chip card module which has individualizing and authenticating properties.
- the chip card module can be individualized by the random distribution of these elements and the module, by recording and storing the significant physical properties resulting from the cluster elements in the chip As such, it can be authenticated before it is installed in a card.
- a further advantageous embodiment of the invention is specified in the subordinate claims. Authenticability is made possible, in particular, by the fact that the distribution of a physical parameter is stored in the chip, this being particularly easy to achieve if the reflection factor of the second conductive layer is used as the physical parameter.
- FIG. 1 shows a first exemplary embodiment of the chip card module
- FIG. 2 shows a second exemplary embodiment of the chip card module
- FIG. 1 shows a chip 1 on a carrier 3 which has contact areas 5 on the side facing away from the chip.
- the chip 1 has an integrated circuit which is connected to connection pads formed on the surface of the chip 1. According to the exemplary embodiment according to FIG. 1, wire bond connections lead from these connection areas through openings 4 in the carrier 3 to the contact areas 5.
- individual cluster elements 8 are formed on the surface of the contact areas 5. These can consist of chrome, for example. These cluster elements 8 are designed according to a specific pattern or a random arranged for distribution. For good and reliable contacting, the cluster elements 8 are then covered by a cover layer 9, which preferably consists of "ITO" (tin doped indium oxide).
- ITO indium oxide
- the cluster elements 8 can also be arranged in a specific pattern, besides individualization, a desired surface pattern of the contact areas can also be generated.
- a layer 9a covering the electrically conductive layer 5 can first be applied, on which the cluster elements 8 are then arranged before everything is common the covering layer 9b is covered. It is particularly advantageous if the layers 9a and 9b are made from the same material as, for example, "ITO". In a further additional configuration, it is advantageous if an adhesion-promoting layer 10 is arranged on the first conductive layer 5. This is, for example, chromium, with chromium also being advantageous as the material for the cluster elements 8. Other layer materials are also titanium and tungsten.
- the chip card module For individualization of the chip card module, it is now necessary to scan at least the individualizing area of the module surface, ie to irradiate it with light, for example, and to detect the change in the reflection factor in a specific spectral range in this area and to store this information in the chip. If the identity or authenticity is to be checked, when using the chip card module, for example when the chip card with the module is inserted into a reading device, the current change in the reflection factor within the predetermined limits is determined within this individualizing area and with the stored data compared. If the measured data match the stored data, the identity or authenticity is confirmed.
- an arrangement according to FIG. 2 is of course possible in such a way that the contact surfaces 5 are not connected to the chip 1 via wire bond connections 2. It is equally possible that the semiconductor chip e.g. is connected to the carrier 3 by means of a flip-chip connection, with rewiring generally being formed on the side of the carrier facing the chip, from which re-wiring is then provided by contacting 7 in through openings 4 to the contact surfaces 5.
- An exemplary embodiment, not shown, is also possible, in which the carrier is produced on a metallic material as a so-called leadframe. With this exception
- the contact areas 5 can then be formed directly as a first conductive layer by the lead frame, the cluster layer 6 then being applied directly to the contact areas.
