Abstract
In an embodiment, a method for producing a substrate having a structured surface includes providing the substrate having a substrate body and having a surface to be structured, forming an absorption layer, a first mask layer and a second mask layer on the surface to be structured, forming openings in the second mask layer in which the first mask layer is exposed, exposing the surface to be structured in a region of the openings, forming depressions in the surface to be structured in the region of the openings to form the structured surface of the substrate and removing the absorption layer from the substrate.
