This paper describes the laser micro structuring of forming tools for hot embossing. The laser micro structuring allows the manufacturing of the required structural sizes and structure forms as well as the machining of the applied tool materials which can not be manufactured with conventional processes like milling. Through the systematic investigation of the influences of single laser parameters it is possible to influence the processing of 2-D and 2½-D micro fluid geometries. For initial experimental investigations the high strength ceramic material silicon carbide is used.
