Cleanroom for micro/nanofabrication


The Binnig and Rohrer Nanotechnology Center is a state-of-the-art exploratory cleanroom fabrication facility combined with "noise-free" labs. These facilities support world-class exploratory research aimed at nanotechnology applications. Both near-term and long-term projects are being pursued.

The cutting-edge cleanrooms, which feature class 100/1000 facilities with class 10 mini-environments, accommodate the following processes:

  • Lithography for pattern definition
  • Wet processing for substrate cleaning and wet chemical etching
  • Thin-film deposition on metals and isolators
  • Dry etching for material removal using reactive gases
  • Thermal processing for oxidation, annealing and vapor phase deposition
  • Metrology/inspection with optical and electron microscopes for surface topology and thickness measurements
  • Backend processes including plating, lapping/polishing, dicing and bonding
  • Polymer waveguide processing for optical interconnects

Processes, most of which are semiconductor-based (silicon, III/V), are being conducted on materials similar to those used in standard semiconductor technology, such as silicon, metals, isolators, polymers, organics and oxides. The Binnig and Rohrer Nanotechnology Center is not a production or a pilot line with fixed processes or wafer sizes because flexibility (up to wafer sizes of 6 inches) is of utmost importance.
