UiO MiNaLab – Micro and Nanotechnology Laboratory

UiO MiNaLab is one of four cleanrooms within the national infrastructure NorFab – The Norwegian Micro- and Nanofabrication Facility, supporting and enabling research and innovation within micro- and nanotechnology.

UiO MiNaLab offers open laboratory access for fabrication, characterization and collaborative research to all students and scientists at the University of Oslo, to the broader (public) research community in Norway and the EU, as well as industry and start-up professionals.

UiO MiNaLab has a 440 sq. m cleanroom with a ISO5 classification and several characterization laboratories. The infrastructure is targeted towards flexibility and provides equipment for the synthesis, modification and characterization of various material systems, such as semiconductors, metals, etc. The facility is operated by the Semiconductor physics group at the Department of Physics, the University of Oslo.
