This experiment-oriented postdoctoral position lies at the interface between fundamental physics and industrial application and supports a fully funded Consolidator Grant from the European Research Council titled “Next-Generation Light Source: Driving plasmas to power tomorrow’s nanolithography (MOORELIGHT)”.

Background
Advanced semiconductor devices are produced using extreme ultraviolet (EUV) light at just 13.5nm wavelength. The recent revolutionary introduction of EUV lithography (EUVL) was the culmination of several decades of collaborative work between industry and science – a Project Apollo of the digital age. EUVL is powered by light that is produced in the interaction of high-energy CO2-gas laser pulses with molten tin microdroplets. The use of such lasers leads to low overall efficiency in converting electrical power to useful EUV light. Replacing gas lasers with much more efficient solid-state lasers may significantly improve efficiency, as well as output power. It is currently however unclear what laser wavelength, and what plasma ‘recipe’ should be used. This is because we lack understanding of the underlying complex physics. The goal of project MOORELIGHT is to deliver the missing insight. 

Project goal
Assessing what plasma conditions are optimal for producing EUV light requires a full characterization of the energy balance: the division of available laser energy into the channels of EUV (and more broadly: all electromagnetic) emission, plasma kinetic energy, and internal energy, as well as laser absorption, reflection, and refraction.

You will supervise a team of several PhD students and have as an objective to design & execute and experiments to characterize the EUV-emitting plasma and understand it to develop optimized plasma recipes. You (and the rest of the team) will be responsible for the setup, execution, analysis, and interpretation of the experiments.

What does ARCNL offer you?

  • Responsibility over a setup including state-of-the-art droplet generators and laser system.
  • The ability to improve your experimental and leadership skills in extensive experimental campaigns that can be designed with a lot of freedom.
  • Collaboration with the in-house theory group, allowing you to perform radiation-hydrodynamics simulations to develop a thorough understanding of the EUV-emitting plasma.
  • Large amount of (image) data and a wide range of existing data analysis tools, allowing you to apply and develop your data analysis skills.
  • Cooperation within a large team of PhD students and postdoc and with a large industrial partner.

 

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 Dutch Research Council (NWO), the University of Amsterdam (UvA), the VU University Amsterdam (VU), and associate partner the University of Groningen (RuG), and the semiconductor equipment manufacturer ASML. ARCNL is located at the Amsterdam Science Park, The Netherlands, and has a size of approximately 100 scientists and support staff. See also www.arcnl.nl 

The research activities of the EUV Plasma Processes group aim at the atomic- and molecular-level understanding of the fundamental dynamics in the operation of contemporary and future plasma-based sources of extreme-ultraviolet (EUV) light for nanolithography.

 

Qualifications

You have (or soon will have) an MSc in (applied) physics. Knowledge about experimental laser physics, ion diagnostics, or atomic and plasma physics, is advantageous. Programming skills (Python) are welcomed. Good verbal and written communication skills (in English) are required.

Terms of employment

The position is intended as full-time (40 hrs / week, 12 months / year) appointment in the service of the Netherlands Foundation for Scientific Research Institutes (NWO-I) for the duration of 3 years, with a salary in scale 10 (CAO-OI) and a range of employment benefits. A favorable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. ARCNL assists any new foreign researchers with housing and visa applications and compensates their transport costs and furnishing expenses.
