Description

Procédé de fabrication d'une carte intelligente comportant un micro-circuit à mémoire inscriptible
La présente invention concerne un procédé de fabrication d'une carte intelligente comportant un micro-circuit ayant au moins une mémoire inscriptible.Method of manufacturing a smart card comprising a micro-circuit with writable memory
The present invention relates to a method of manufacturing a smart card comprising a micro-circuit having at least one writable memory.

A l'heure actuelle, pour fabriquer une carte intelligente munie d'un microcircuit, on réalise tout d'abord un programme de gestion contenant toutes les instructions nécessaires pour gérer le fonctionnement du micro-circuit, on implante ensuite le programme de gestion dans le micro-circuit par une opération de fonderie, puis l'on fixe le micro-circuit sur un corps de carte, et l'on personnalise la carte en enregistrant par exemple les données permettant d'identifier cette dernière ainsi que son futur porteur. At present, to manufacture a smart card fitted with a microcircuit, a management program is first carried out containing all the instructions necessary to manage the operation of the micro-circuit, then the management program is implemented in the micro-circuit by a foundry operation, then the micro-circuit is fixed on a card body, and the card is personalized by recording, for example, the data making it possible to identify the latter as well as its future holder.

Un tel procédé de fabrication ne donne toutefois pas pleinement satisfaction. However, such a manufacturing process is not entirely satisfactory.

En effet, lorsque le programme de gestion comporte des erreurs dites "bugs" ou lorsque l'on souhaite lui apporter des améliorations, on doit nécessairement effectuer une nouvelle opération de fonderie pour implanter dans d'autres microcircuits le programme corrigé ou perfectionné.Indeed, when the management program contains so-called "bugs" errors or when it is desired to make improvements to it, a new foundry operation must necessarily be carried out in order to implant the corrected or improved program in other microcircuits.

Les opérations de fonderie, qui sont réalisées par des spécialistes peu nombreux, ont toutefois l'inconvénient d'être fort coûteuses et de demander beaucoup de temps. Foundry operations, which are carried out by few specialists, have the disadvantage of being very expensive and time consuming.

La présente invention se propose plus particulièrement de remédier à cet inconvénient et, pour ce faire, elle a pour objet un procédé de fabrication d'une carte intelligente comportant un micro-circuit ayant au moins une mémoire inscriptible, qui se caractérise en ce qu'il consiste à réaliser un programme de chargement contenant le minimum d'instructions aptes à rendre ultérieurement intelligent le micro-circuit, à implanter le programme de chargement dans le micro-circuit par une opération de fonderie, à fixer sur un corps de carte le micro-circuit programmé, à réaliser un programme de gestion contenant des instructions aptes à gérer le fonctionnement du micro-circuit, à charger le programme de gestion dans la mémoire inscriptible du micro-circuit, à déconnecter le programme de chargement afin de faire fonctionner le microcircuit sur son programme de gestion, et à personnaliser la carte.  The present invention more particularly proposes to remedy this drawback and, to do this, it relates to a method of manufacturing a smart card comprising a micro-circuit having at least one writable memory, which is characterized in that it consists in carrying out a loading program containing the minimum of instructions able to make the micro-circuit intelligent later on, in implanting the loading program in the micro-circuit by a foundry operation, in fixing the micro on a card body -programmed circuit, to carry out a management program containing instructions able to manage the operation of the micro-circuit, to load the management program into the writable memory of the micro-circuit, to disconnect the loading program in order to operate the microcircuit on its management program, and to personalize the card.

Grâce à ce procédé, il n'est plus nécessaire d'utiliser les services d'un fondeur pour implanter dans les micro-circuits des programmes de gestion auxquels on a apporté des modifications pour corriger des bugs, ou pour obtenir de plus grandes performances. L'industriel qui a fixé sur des corps de carte les micro-circuits dans lesquels le programme de chargement a été implanté n'a en effet qu'à effectuer des connexions électriques pour charger dans la mémoire inscriptible de ces micro-circuits le programme corrigé ou perfectionné. Thanks to this process, it is no longer necessary to use the services of a founder to implement management programs in the micro-circuits to which modifications have been made to correct bugs, or to obtain greater performance. The industrialist who fixed the micro-circuits in which the loading program was installed on card bodies only has to make electrical connections to load the corrected program into the writable memory of these micro-circuits or perfected.

On conçoit ainsi aisément que le prix de revient des cartes intelligentes obtenues par la mise en oeuvre du procédé selon l'invention peut être nettement plus faible que celui des cartes intelligentes fabriquées actuellement. It is thus easily understood that the cost price of the smart cards obtained by the implementation of the method according to the invention can be significantly lower than that of the smart cards currently manufactured.

Les différences entre le procédé utilisé actuellement et le procédé conforme à l'invention ressortiront clairement des dessins annexés dans lesquels
- la figure 1 est un diagramme illustrant un mode d'exécution du procédé utilisé actuellement ; et
- la figure 2 est un diagramme illustrant un mode d'exécution du procédé conforme à l'invention.The differences between the process currently used and the process according to the invention will become clear from the appended drawings in which
- Figure 1 is a diagram illustrating an embodiment of the method currently used; and
- Figure 2 is a diagram illustrating an embodiment of the method according to the invention.

En se référant tout d'abord à la figure 1, on constate que le procédé actuel comprend une étape consistant à réaliser le programme de gestion contenant toutes les instructions nécessaires pour gérer le fonctionnement des microcircuits des cartes à mémoire, une étape consistant à envoyer le programme de gestion chez un fondeur spécialisé afin que celui-ci l'inscrive dans le silicium des micro-circuits en masquant une mémoire ROM de ces derniers, une étape consistant à récupérer les micro-circuits programmés et à fixer (ou encarter) les micro-circuits programmés sur des corps de carte, et une étape consistant à personnaliser les cartes. Referring first to FIG. 1, it can be seen that the current method comprises a step consisting in carrying out the management program containing all the instructions necessary for managing the operation of the microcircuits of the memory cards, a step consisting in sending the management program at a specialized smelter so that the latter inscribes it in the silicon of the micro-circuits by masking a ROM memory of the latter, a step consisting in recovering the programmed micro-circuits and fixing (or inserting) the micro -circuits programmed on card bodies, and a step consisting in personalizing the cards.

Lorsque l'on a corrigé des bugs décelés dans le programme de gestion ou apporté des améliorations à ce dernier, on est contraint d'envoyer le programme modifié au fondeur afin que celui-ci l'inscrive dans le silicium d'une nouvelle série de micro-circuits, ce qui est long et coûteux. When we have corrected bugs detected in the management program or made improvements to it, we are forced to send the modified program to the founder so that the latter inscribes it in the silicon of a new series of micro-circuits, which is long and expensive.

En se référant maintenant à la figure 2, on constate que le procédé conforme à l'invention comprend quant à lui une étape consistant à réaliser un programme de chargement contenant le minimum d'instructions capables de rendre les micro-circuits intelligents, une étape consistant à envoyer le programme de chargement chez un fondeur spécialisé pour que celui-ci l'inscrive dans le silicium des micro-circuits en masquant la mémoire ROM de ces derniers, une étape consistant à récupérer les micro-circuits ainsi programmés et à fixer les micro-circuits programmés sur des corps de carte, une étape consistant à réaliser le programme de gestion contenant les instructions permettant de gérer le fonctionnement des micro-circuits, une étape consistant à charger ce programme dans une mémoire inscriptible EPROM ou EEPROM des micro-circuits, une étape consistant à déconnecter le programme de chargement de façon à permettre le fonctionnement des micro-circuits sur leur programme de gestion, et une étape consistant à personnaliser les cartes. Referring now to FIG. 2, it can be seen that the method according to the invention comprises a step consisting in carrying out a loading program containing the minimum of instructions capable of rendering the microcircuits intelligent, a step consisting to send the loading program to a specialized smelter so that the latter inscribes it in the silicon of the micro-circuits by masking the ROM memory of the latter, a step consisting in recovering the micro-circuits thus programmed and in fixing the micro circuits programmed on card bodies, a step consisting in carrying out the management program containing the instructions making it possible to manage the operation of the micro-circuits, a step consisting in loading this program into a writable EPROM or EEPROM memory of the micro-circuits, a step consisting in disconnecting the loading program so as to allow the operation of the micro-circuits on the ur management program, and a step of personalizing the cards.

Lorsque l'on a corrigé des bugs dans le programme de gestion ou apporté des améliorations à ce dernier, il n'est plus nécessaire maintenant d'avoir recours à un fondeur, le programme de gestion modifié pouvant être chargé dans les micro-circuits, immédiatement après l'encartage. When we have corrected bugs in the management program or made improvements to it, it is no longer necessary to have recourse to a founder, the modified management program being able to be loaded in the micro-circuits, immediately after inserting.

On conçoit donc aisément que le procédé conforme à l'invention est moins coûteux que le procédé actuel et qu'il permet des gains de temps appréciables.  It is therefore easily understood that the method according to the invention is less expensive than the current method and that it allows appreciable time savings.
