Momentous inventions are rooted in groundbreaking discoveries. That is why at ARCNL we venture into unknown territory, while at the same time looking towards industry for inspiration. EUV lithography is currently the most promising new technology for semiconductor production. We therefore mainly focus on the physics that is central to the generation of high intensities of extreme ultraviolet light and its use in nanolithography. We try to be the first to understand and control certain physical processes at the atomic scale and beyond. Over time our program will evolve so that we can remain at the frontier of nanolithography research.

ARCNL currently has eight research groups, each exploring its own field:

  • EUV Plasma Modeling

    Which processes take place within an EUV emitting plasma? And how do they influence the amount of EUV light and debris the plasma emits? To answer these questions, this group …

  • EUV Photoresists

    This group studies the chemical changes that occur within a wide range of photosensitive materials in response to incident EUV light. The aim is to gain fundamental understanding in order …

  • EUV Photoemission

    This joint group of ARCNL and AMOLF uses photoelectron spectroscopy – detecting electrons knocked out of a material by incoming photons – to study molecular properties of EUV photoresist materials …

  • Nanophotochemistry

    Wafers are covered with a photosensitive called resist so that patterns can be transferred to them from masks. This group focuses on the effects of the interaction between EUV light …

  • EUV Plasma Processes

    This group uses an extensive diagnostic toolset to characterize and understand the physics of plasma sources of EUV light at the atomic level.

  • EUV Targets

    This group uses ultrafast lasers and spectroscopy to study at every possible timescale the interaction between high-intensity laser light and metals passing through the four phases of matter: solid, liquid, …

  • EUV Generation & Imaging

    This group aims to obtain a fundamental understanding of the physical processes occurring in laser-produced plasmas and to control the emission of radiation and particles. It is also exploring the …

  • Nanolayers

    This group studies surfaces, interfaces, and very thin films on the atomic scale. The knowledge it generates is relevant for the delicate optics and other essential components of modern lithography machines.
