PhD: Charging and secondary electron emission for electron microscopy

Work Activities

The goal of the project is to better understand charging of surfaces and how it affects materials properties such as secondary electron emission in the context of scanning electron microscopy for metrology applications. The experiments on materials used in the semiconductor industry will be interpreted in the context of electron scattering simulations performed by collaboration partners. As a PhD student you will use state of the art electron spectroscopy and surface preparation tools to unravel the physical and chemical changes at surfaces induced by charging. You will determine how the secondary electron yields of surfaces are affected by the presence of excess charge, contamination, and defects.

This project is part of a larger KIC project, “Foundations for electron-beam metrology and inspection”, in which knowledge institutes Delft University of Technology and ARCNL are working together with high-tech company ASML. You will perform this project in close collaboration with a team of PhD students and postdocs working on this project at ARCNL and at Delft University of Technology, and with researchers at the Dutch semiconductor manufacturing equipment company ASML. At ARCNL you will be embedded in the Materials & Surface Science for EUVL group of dr. Roland Bliem and work closely together also with the Light/Matter Interaction group of Prof. dr. Paul Planken.

Qualifications

You have a university degree in physics, physical chemistry, or a related field that satisfies the Dutch university requirement to enter into a PhD program.

Good verbal and written communication skills (in English) are required.

Prior experience with surface science, ultra-high vacuum, and spectroscopy techniques is considered an advantage for the project.

Work environment

ARCNL performs fundamental research, focusing on the physics and chemistry involved in current and future key technologies in nanolithography, primarily for the semiconductor industry. While the academic setting and research style are geared towards establishing scientific excellence, the topics in ARCNL’s research program are intimately connected with the interests of the industrial partner ASML. The institute is located at Amsterdam Science Park and currently employs about 100 persons of which 65 are ambitious (young) researchers from all over the globe. www.arcnl.nl

Working conditions

The position is intended as full-time (40 hours / week, 12 months / year) appointment in the service of the Netherlands Foundation of Scientific Research Institutes (NWO-I) for the duration of four years, with a starting salary of gross € 2,781 per month and a range of employment benefits. After successful completion of the PhD research a PhD degree will be granted at a Dutch University. Several courses are offered, specially developed for PhD-students. A favorable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. ARCNL assists any new foreign PhD-student with housing and visa applications and compensates their transport costs and furnishing expenses.
