Innovation and Upscaling

Whereas laboratory scale experiments are good for proof-of-principle, new scientific challenges arise when micro and nano structuring is driven towards industrialisaton.

The main activities are the design, the manufacture, the development of novel micro- and nanofabrication methods, the characterisation of nano- and microstructured components, and the assembly of complex microsystems. For this a large diversity of micro- and nanofabrication techniques like polymer patterning and replication by roll-to-roll process, lithography processes and 3D patterning are available.
