About this position

Use of Physics Informed Neural Networks to realize new (metrology) technologies has the potential to have a large impact on the high tech industry. This project is a first step for TNO to explore this potential and to find out how to apply such technology to some of the Dutch high tech industry opportunities.

What will be your role?

In this project we want to explore the suitability of Physics Informed Neural Networks (PINNs) to support advanced metrology techniques in semiconductor manufacturing. PINNs are a form of neural networks that incorporate physics equations and corresponding boundary conditions to improve robustness and efficiency. We will focus on a use case involving InfraRed Atomic Force Microscopy (IR-AFM), a technique allowing IR-spectroscopy with nm-scale lateral resolution. This technique is relevant for characterizing the increasingly complex structures on computer chips, along with their production processes. In this project, we will use PINNs to predict the Electro-Magnetic field strength as function of a measured AFM tip shape, based on training on the EM field obtained from FEM simulations with idealized tip shapes. We will compare PINN simulation results to measurements. This project is to be the first step in a larger effort towards reverse modelling of sample characteristics from measurements using PINNs.

You will work in a team with a strong background in developing AFM technologies consisting primarily of physicists. You will however also interact with a team based in The Hague with a strong background and infrastructure related to Artificial Intelligence.

What we expect from you

skills / interests we’re looking for:

  • Experience with development and training of neural networks
  • Affinity with physics and maths (esp. PDE’s)
  • Experience with FEM is a pre
  • Based on interest, you can get to perform AFM measurements.
  • Flexibility to perform work across different departments at TNO and the university.
  • What you'll get in return

    You want an internship opportunity on the precursor of your career; an internship gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation. That’s why we attach a great deal of value to your personal and professional development. You will, of course, be properly supervised during your work placement and be given the scope for you to get the best out of yourself. Furthermore, we provide:

  • A highly professional, innovative internship environment, within a team of top experts.
  • A suitable internship allowance ( euro for wo-, hbo- and mbo-students, for a full-time internship).
  • Possibility of eight hours of free leave per internship month (for a full-time internship).
  • A free membership of , where you can meet other TNO professionals and join , such as sports activities, (work-related) courses or the yearly ski-trip.
  • Use of a laptop.
  • An allowance for travel expenses in case you don’t receive an OV-card.
