About this position
PhD position at Delft University of Technology (TU Delft) in Amplitude & Phase Control in Optical Metrology.
This project focuses on optical metrology, coherent optical scatterometry, electromagnetic scattering, signal processing, mathematics, and machine learning. You will work on ideation, modeling, and experimental validation of novel techniques for semiconductor manufacturing, with the goal of improving nanoscale measurement of chip features, overlay errors, and other geometrical parameters.
The research is embedded in a physics environment with strong interaction across applied physics, applied mathematics, and high-tech industry partners. The work includes developing methods to control the amplitude and phase of the input probe, deriving field constraints from first principles, and improving performance when combined with local/global optimization, priors, and neural networks.
Eligibility highlights: an MSc in Applied Physics, Electrical Engineering, or equivalent; strong theoretical foundations; interest in optics and scattering; coding ability or willingness to learn; good English communication skills; and a collaborative, integrity-driven mindset.
Funding and conditions: this is a 4-year PhD employment at TU Delft, with salary from €3204 to €4051 gross per month depending on year, plus 8% holiday allowance and an 8.3% end-of-year bonus. TU Delft also mentions health insurance discounts and a monthly work costs contribution.
Application deadline: 15 October 2026. Apply online and upload a motivation letter, CV, grades, and a summary of your thesis/publications. Contact Dr. O. El Gawhary for more information.
