Functie omschrijving

We are looking for a motivated and skilled post-doctoral researcher to carry out advanced micro/nano fabrication research on free-standing transmission gratings for spectral unraveling of extreme ultraviolet (EUV) lithography light sources.

The XUV Optics Group at Twente, in collaboration with ARCNL in Amsterdam, has started a new multidisciplinary research program on these topics. We develop forefront fundamental research, relevant to high tech applications ( The research will take place in a state-of-the-art thin film laboratory and cleanroom within the MESA+ Institute for Nanotechnology at the University of Twente, in collaboration with various academic and industrial partners.

Your goal is to develop the advanced free-standing transmission gratings using the well-established micro/nano fabrication infrastructure. Previously we have fabricated transmission gratings with 50 nm features. The challenge includes:

  • Exploiting deposition and micro/nano-structuring techniques for patterning and releasing structures with dimensions below 100 nm.
  • Developing the understanding of the material properties and fabrication processes for stable free-standing grating structures at these dimensions.
  • Characterizing the deposited films and fabricated structures using characterization techniques such as AFM, XRD, SEM and others.
  • Exploring alternative materials, fabrication techniques and designs for higher optical performance and reliability.
