Semiconductor devices continue to get smaller, contain more materials and have increasingly complex geometries. To ensure that the semiconductor device production yields remain high, the accuracy of all metrology methods as are used for process control must be disruptively improved. Metrology with a Scanning electron microscope (SEM) plays a crucial role for process control, and improving the interpretability of SEM signals is essential for further development of the semiconductor industry. Accurate modeling of the beam-sample interaction for real device geometries has to bring the required new insights.
The Delft university of technology developed Nebula, an open source electron scattering simulator, which can simulate scanning electron microscopy (SEM) images. Nebula is used within ASML to obtain a better understanding of SEM signal formation. While Nebula (re)produces experimentally observed trends in SEM imaging qualitatively, an accuracy gap remains between simulated and real SEM images.
The main goal of the project is to improve the accuracy of Nebula by e.g., including charging effects, improve the physical models for low energy.
The project is a collaboration between Delft university of technology and ASML.
The PhD candidate will work at the Delft university of technology mainly. It is expected that, at least once every two weeks during regular working weeks, the PhD candidate will work from an ASML office in Veldhoven / Eindhoven and engage in various discussions.
The job requires a master degree in Physics, Computer science or Electrical engineering
We are looking for a motivated PhD candidate with the following expertise:
Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the nl/onderwijs/opleidingen/phd/admission">Graduate Schools Admission Requirements.
Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts. An initial 1,5 year contract with an official go/no go progress assessment within 15 months. Followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met.
Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2541 per month in the first year to € 3247 in the fourth year. As a PhD candidate you will be enrolled in the TU Delft Graduate School.
