The DUV Optical Column department is responsible for developing the optical systems that are used for projecting an ic-design layer onto the wafer. The department is divided into multiple groups, each of which works in its own specialist subsystem. In this function we are searching for a modelling expert with optimization knowledge.

Job Mission

To contribute to various stages of development, integration, issue resolution and qualification of the Lens Models. The lens models are the main optimization algorithms for reducing optical aberrations in the lens. The lens models optimize overlay, focus and imaging by computing adjustments of the lens actuators.These computations need to be finished within a limited amount of time.

Job Description

  • Specifies and designs the MATLAB based lens models, supervises the implementation of the final machine SW-models and carries out the optical tests and adapts the design accordingly
  • Keeps close contact with internal stake holders to ensure interfaces between sub functions are maintained andtechnical content is aligned
  • Ensures the modularity, reparability and serviceability of the designs and control loops
  • Drives the integration of the improvements of optical sub-system and control models into ASML products, analyses the problems, and drives solutions
  • During customer escalations, analyses the problem and defines containment and solution.


Technical University Master’s or PhD in Mathematics or Physics.


  • Experience in MATLAB and/or Python
  • Experience in the field of optimization methods and solvers, i.e. quadratic programming
  • Experience in the field of high-tech system development
  • Broad knowledge of optical systems and system control algorithms
