PhD-student: Modelling laser-driven plasma sources of EUV light for nanolithography

Date posted November 13, 2018
Type PhD positions

This PhD projects aims at predictive modelling of laser-produced tin plasma sources of extreme ultraviolet (EUV) radiation for nanolithography. You will complement current experimental activities with analytical and numerical theoretical models. The common goal of the experiments and theory activities in the group is to understand these laser-produced, high-density plasma sources at the fundamental level. For this purpose, it is envisaged that you will employ and combine existing state-of-the-art atomic data and radiation-hydrodynamics codes in close collaboration with an experienced postdoctoral researcher. In a team effort, we will answer the following questions: Which physical processes determine the efficiency of the conversion of drive laser energy into EUV power and what is its fundamental limit? How can we control the expansion dynamics of this plasma and prevent the plasma from inflicting damage to its surroundings? Answering these questions by focusing on the physics fundamentals will pave the way for more powerful plasma sources of EUV light and enable the continuation of Moore’s law, producing ever more powerful chips.

About the group

The Advanced Research Center for Nanolithography (ARCNL) focuses on the fundamental physics and chemistry involved in current and future key technologies in nanolithography, primarily for the semiconductor industry. ARCNL is a public-private partnership between the Netherlands Organisation for Scientific Research (NWO), the University of Amsterdam (UvA), the VU University Amsterdam (VU) and the semiconductor equipment manufacturer ASML. ARCNL is located at the Science Park Amsterdam, The Netherlands, and is currently building up towards a size of approximately 100 scientists and support staff. See also www.arcnl.nl

You will be embedded in the EUV Plasma Processes team at ARCNL, which frequently interacts with our industrial partner ASML. The research activities of the EUV Plasma Processes group aim at the understanding of the basic dynamics on an atomic and molecular level of the operation of contemporary and future plasma-based sources of extreme-ultraviolet (EUV) light for nanolithography.

Qualifications

You have an MSc in (applied) physics. Knowledge in the fields of atomic and plasma physics, or laser physics is advantageous. Good verbal and written communication skills (in English) are required.

Terms of employment

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. After successful completion of the PhD research a PhD degree will be granted at the Vrije Universiteit Amsterdam (VU). Several courses are offered, specially developed for PhD-students. ARCNL assists any new foreign PhD-student with visa applications and compensates their transport costs and furnishing expenses.
