Expertise in seamless large area micro- and nanostructuring on large areas in photoresists. Additional experience in tooling, e.g. metallic (nickel) tools, PDMS or polyermic molds for replication purposes. Such molds might be used for high volume mass replication processes like UV-roll-to-roll embossing, hot-embossing, injection molding, etc. Besides interference lithography, other tooling technologies like UV-lithography, diamond cutting, e-beam structuring, ... are well known.
