摘要：The invention relates to a method for producing a support element for anintegrated circuit component which is to be included in a data carrier card. According tosaid method, conductor strips which have contact surfaces on both respective flat sidesof the support element are etched out of a conductive layer. One side of said contactsurface is connected to a respective connecting contact of the IC component and theother side serves as an external contact. The external contact surfaces and theircorresponding conductor strips are coated with an additional electrically conductiveprotective layer. During a first step of the method, the electrically conductive layer (1) iscoated with a liquid or pasty curable coating material (2) on one flat side on the contactsurface points (2b) which have been provided in order to make the connecting contact.The remaining uncoated surface regions (3a, 3b, 3c) of said flat side are then coated with aliquid or pasty curable non-conductive material (3). In subsequent steps of the method,the conductor strips (7) and contact surfaces are etched out of electrically conductivelayer (1) and are coated with the additional electrically conductive protective layer (5). In

the final step of the method, the coating material (2) which has been applied only to oneside is removed. The inventive method produces a support element which lacks theconventional support film usually used for the electrically conductive layer. This leads toa reduction in the height of the unit formed by the IC component and support element,despite a slightly thicker electrically conductive layer achieved by a correspondingmaterial composition of the copper foil which is preferably used.
