Postdoctoral Fellow

For Algorithms and software development for EUV wafer metrology

Your tasks

Reliable wafer metrology is a key requirement to support the semiconductor industry in the development of future technology nodes. The device size scaling driven by Moore’s law make the resolution specification for wafer metrology a moving target. The Advanced Lithography and Metrology group is dedicated to the exploration of new and alternative techniques for semiconductor metrology. Currently we are developing REGINE, a new end station for the XIL-II beamline at the SLS synchrotron. REGINE is a wafer inspection microscope based on grazing-incidence coherent diffraction imaging at EUV.
  • Support the development of the REGINE end station
  • Develop Coherent Diffraction imaging algorithms and software for image reconstruction
  • Explore the potential of a deep learning approach for phase retrieval from EUV diffraction data
  • Perform research of highest quality and publication in high profile journals

Your profile

  • PhD degree in physics, engineering or computer science
  • Experience with C++ and CUDA
  • Hands-on experience in one more of the following fields: coherent diffraction imaging, ptychography, image processing, neural networks
  • Experience with image processing and scripting languages like Python and Matlab will be an advantage
  • You are a proactive and highly motivated team player and you are fluent in written and spoken English

We offer

Our institution is based on an interdisciplinary, innovative and dynamic collaboration.
