Abstract

The invention relates to a method of structuring of a substrate by providing a polymerization starter layer on the substrate, applying a radiation field on the polymerization starter layer for selectively reducing a density of polymerization starters of the polymerization starter layer, applying monomers and then polymerizing of the monomers, the polymerization being initiated by the starters of the polymerization starter layer, and structuring the substrate using the polymerized monomers as a mask.
