Company history

The story of Beamfox began in 2014 when Leonardo Midolo and Søren Stobbe were developing novel quantum nanocomponents at the Niels Bohr Institute in Copenhagen. With the increasing complexity of their devices, their requirements for electron-beam lithography kept growing. By 2014, they had hit a main roadblock. Although electron-beam lithography is the state-of-the-art method for high-resolution lithography, the method is inherently limited by backscattering of electrons, leading to unwanted exposures and deformed nanostructures. This is known as proximity effects and with no satisfactory solution available, Leonardo decided to take matters in his own hands: he created an algorithm that corrects proximity errors. The algorithm quickly became a workhorse for the photonics research at the Niels Bohr Institute. In 2016, Leonardo and Søren teamed up with Anders Esbensen and founded Beamfox Technologies to develop our first product: Beamfox Proximity.


Beamfox Technologies develops and commercializes software solutions for proximity effect correction in the R&D market. For too long, proximity effect errors have limited researchers in many areas of nanotechnology. Beamfox Proximity provides a simple and user-friendly interface to our state-of-the-art proximity effect correction algorithm. In everything we do, we take the process engineer’s perspective to make proximity effect correction simpler, easier, and faster than ever before.
