Abstract:
A chip card comprising a card of a plastics material which is capable of elastically withstanding a relative curvature, in which a microelectronic data processing chip is encased and to which a thin microelectronic wafer of a semiconductor material is affixed,said wafer being sub-divided into a smaller number of juxtaposed chips disposed in a given layout with electrical links joining said juxtaposed chips so as to provide electrical continuity therebetween, and said juxtaposed chips being separated from one another so that adjacent chips are separated from each other by a separating strip of said plastics material the separating strip separating said adjacent chips from each other being of a predetermined width and said width being such as to permit each said separating strip of plastics material to be subjected to a bending corresponding to the relative curvature which the card of plastics material is capable of elastically withstanding, without causing said adjacent chips to become unstuck and/or break.
