Patent ID: 8077114

Claim:
A process for the production of an electrically conductive structure on a carrier substrate ( 10 ) including at least two conductor track portions ( 21 , 22 ; 31 , 32 ) spaced in a region ( 4 ) of a width b over the entire width b at between 500 μm and 1 μm, the process comprising the steps of: producing a conductive layer ( 11 ) in the form of the conductor track portions ( 21 , 22 ; 31 , 32 ) on the surface of the carrier substrate ( 10 ); and depositing a metallic coating ( 12 ) forming the electrically conductive structure on the conductive layer by application of a flow of current in an electrolyte which contains a dissolved coating metal, wherein the conductive layer ( 11 , 30 ) is produced in the form of conductor track extensions ( 23 , 24 , 25 , 26 ) which are arranged on both sides of the conductor track portions ( 21 , 22 ; 31 , 32 ) and which are convexly curved away from the oppositely disposed conductor track portion ( 22 , 21 ; 32 , 31 ).
