Producing fine structuring of material involves applying material and auxiliary material to substrate, structuring surface by ablating auxiliary material, etching material exposed in some areas

摘要

The method involves applying the material (20) to a substrate (10), applying an auxiliary material (30) to the substrate, structuring the surface by ablating auxiliary material and etching away the material exposed in some areas (40). The ablation is performed using a laser and a ceramic substrate can be used as the substrate. Independent claims are also included for a device with fine structuring produced by the inventive method.
