Abstract
A technique was developed for dry chem. structuring of polymeric surfaces based on the principle of excimer laser irradn. in reactive gas atm. This technique is characterized by a high resoln. and a negligible amt. of chems. The procedure consists of only a few processing steps, in contrast to conventional lithog. structuring methods. Also wetting problems do not play a role as they do in printing techniques. The technol. provides the possibility of tailoring the chem. and topog. surface properties from ultrahydrophobic to hydrophilic or to functionalize areas of choice in the mm range with a chem. group of defined d. Mask imaging can be applied for microstructuring the surface with new properties, e. g. for microarrays.
