Element mit strukturierter Oberflaeche sowie Verfahren zu seiner Herstellung

DE1004011363 A UPAB: 20051109 NOVELTY - The unit has an amorphous carbon layer formed on a structured upper surface of a substrate. Locally modified and defined nano-scaled areas has increased electrical conductivity and/or increased layer thickness and are formed opposite to the amorphous carbon layer in the structure. Areas represent information in a definitive and preferred arrangement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a nano- structured unit. USE - Used as an information storage unit, and a tool for manufacturing coin or other molding articles and in optical applications. ADVANTAGE - The locally modified and defined nano-scaled areas with increased electrical conductivity and/or increased layer thickness are formed opposite to amorphous carbon layer, thus increasing storage capacity per unit area of digital or analog and highly condensed information for long duration, and hence enabling multiple applications in the unit. The areas represent information in the definitive and preferred arrangement, thus simplifying and shortening process of reading information in the arrangement. The amorphous carbon layer exhibits good mechanical and chemical characteristics, thus achieving sufficient long-term stability of materials used in the unit
