About the Münster Nanofabrication Facility (MNF)

The Münster Nanofabrication Facility (MNF) is a Core Science Facility administrated by the University of Münster (WWU) and operates two cleanrooms in CeNTech and the Center for Soft Nanoscience (SoN).

A state-of-the-art machine park for advanced nanofabrication, the MNF is an internal service provider offering cleanroom laboratory space to an interdisciplinary research community of graduate students, postdocs and research associates in chemistry, physics and biology.

The initial cleanroom in CeNTech was completed in 2003 and serves a diverse research community in nanophysics, nanobiology, nanochemistry and materials science. Following the University's expanding presence in nanoscience, the original facility required significant upgrades to meet the needs of researchers and remain competitive with peer institutions. Through the approval of the SoN research program, the WWU received a multimillion euro investment including capital equipment upgrade, as well as several large instrument grants.

In 2017 the MNF expanded into brand new cleanroom facilities in the SoN building.

The new Si-Au focused ion beam and electron microscope was delivered on December 9th and is currently being installed in the SoN Velion zone (room 100.045).

We are excited to start working with this new multi-functional system beginning in February 2020.

Introducing GDSHelpers!

GDSHelpers is a Python-based, easy-to-learn, open-source software package, which allows users to quickly generate arbitrary photonic and other devices. Users can automate pattern generation for nano-structuring and export patterns in GDSII- and OASIS-format (for describing 2D-masks). Currently, the focus is mainly on photonic and superconducting circuitry.

The Python library GDSHelpers holds a growing list of parts, which can be composed into larger circuits.

Researchers at the University of Münster have now developed an interface that couples light sources for single photons with nanophotonic networks. This interface consists of so-called photonic crystals, i.e. nanostructured dielectric materials that can enhance a certain wavelength range when light passes through. Such photonic crystals are used in many areas of research, but they had not previously been optimized for this type of interface. The researchers took particular care to achieve this feat in a way that allows for replicating the photonic crystals straightforwardly by using established nanofabrication processes.

The TERA-Fab™ E series is the world’s first beam pen lithography (BPL) tool, which provides the user with a way to prototype functional electronic devices, perform highly-localized photochemistry relevant to biology and medicine, and make the types of architectures traditionally made with photolithography, but in a mask-free fashion and with a diffraction-unlimited, sub-250 nm resolutions. With the E series, the user can rapidly create nanopatterns of any design across square micrometer to tens of square millimeter areas using a wide range of photosensitive materials.

On the 6th of November 2019, MNF scientists had the opportunity to learn more about the TERA-Fab™ E series from Dr. Andrey Ivankin, the chief technology officer and co-founder at TERA-print.

The new state-of-the art molecular printer installed in the Münster Nanofabricaton Facility (MNF) addresses the needs of users working in various fields of nanoscience ranging from biomedicine, material sciences to microelectronics. Allowing for flexible choice and combination of various functional modules, it can cover a wide range of applications and research projects, and has the following features:

  • Base printing module with a choice of different printing technologies (ranging from cantilever arrays and soft polymeric stamps to microcapillary pens)
  • High-Resolution module for increased patterning control down to the low nanoscale
  • Climate module for controlled humidity
  • Optical module for in-situ process control and analysis.

On the 4th and 5th of November 2019, MNF scientists participated in a workshop to learn more about this exciting new technology.
