Abstract:
The invention concerns a contactless smart card comprising inhibiting means. It comprises a card body, an antenna (25) and, connected to said antenna connecting terminals (23, 24), an integrated circuit chip. Said card is characterised in particular in that the connecting terminals to the antenna are further connected to conductive via holes (28) emerging at the card surface, and the junction (26) based on an electrically conductive substance, designed to be removed by scraping when it is first used, is flush with the card surface and connects the conductive via holes.
Abstract:
The invention concerns a method for protecting integrated circuit chips (100) of a silicon wafer (10) comprising the following steps: cutting out the silicon wafer (10) so as to disengage the chips from the integrated circuit; applying a fluid insulating material (150) on the rear surface (104) of the wafer so as to coat the flanks (106) of each chip (100) of the integrated circuit with a thin insulating layer. The insulating material may be applied by spraying, screen printing, dip coating, casting or any other means. The invention further concerns integrated circuit chips whereof the flanks are protected by an insulating material to prevent electrical malfunction caused by contact of a conductive material on the flanks of the chips.
Abstract:
The invention relates to a method for producing an integrated circuit, including a step whereby a module (12) is created and fixed on the body of a card (20) and provided with an integrated circuit (14) and contact pads (16). The invention is characterised in that the step in which the module (12) is created comprises a stage that consists in forming slots in a plate element (26) that is made from a conducting material, whereby said slots define at least partially the areas of the plate element (20) that will form the contact pads. The invention is also characterised by a subsequent step that consists in coating a lower face (32) of the plate element at least partially with adhesive matter (30) to enable the module (12) to be fixed to the body of the card (20) at a later stage.
Abstract:
The invention concerns a method for making smart cards capable of operating with or without contact called mixed cards and contactless smart cards. In order to avoid the risk of deteriorating the antenna the method consists in producing an antenna comprising at least two turns, on a support sheet, said antenna having its turns located outside the connecting pads, and in providing an insulating bridge so as to connect each of the antenna ends to a connection pad respectively.
