Internship: Shaping laser-induced tin targets for EUV generation
In our lab, we investigate the interaction of laser pulses with liquid tin microspheres to advance the knowledge of the physical processes that rule the extreme ultraviolet light (EUV) generation currently used in state-of-the-art nanolithography machines. These machines use a two-step process to generate EUV light that is later on used to inscribe the smallest microchips with the highest spatial resolution. In the first step, a laser-pulse illuminates one side of a tin droplet creating a plasma at its surface, whose rapid expansion transfers momentum to the droplet inducing a controlled propulsion and deformation into a pizza-like shape. A few microseconds after the initial kick, a second, more intense, laser pulse illuminates the expanding material and generates a tin plasma that preferentially generates EUV light at a wavelength of 13.5 nm. In this (BSc) project, we propose to investigate the above-mentioned first step by establishing a link between the experimental observations of the initial plasma kick and the subsequent propulsion and expansion dynamics. In order to quantify the fluid dynamic properties, movies of the dynamic process will be used to track the center-of-mass position and the radius as a function of time to extract the propulsion and expansion velocities. The intensity of the plasma (bright spot on the image) will be systematically studied and will serve as a link between the initial laser features and the subsequent fluid dynamics. During the first stage of the (BSc) project there will be lab tours where we will explain the experimental systems and methods. The core of the project will focus on data analysis of pre-existing experimental data with the possibility of acquiring new data later on. Overall, this project will help us to understand collectively different stages of the laser-tin interaction process, involving mechanisms that are explained using laser physics, plasma physics and fluid dynamics.

INTERNSHIP OPPORTUNITIES
Attention all motivated students from the University of Groningen. Are you ready to drive your own project and gain hands-on experience in cutting-edge research? Have a look at the Advanced Research Center for Nanolithography (ARCNL), a unique research institute that combines academic excellence with industrial challenges. We offer a range of exciting internship opportunities in experimental and theoretical physics and chemistry. As an intern, you will be part of a research group that is dedicated to understand fundamental principles. These insights are beneficial to the semiconductor industry. If you start an experimental project, you will work in our state-of-the-art labs and facilities. Our research program is divided into three departments focusing on EUV light generation, metrology solutions, and material degradation and manipulation. Each department focuses on critical aspects of the semiconductor industry and offers a range of projects that have the potential to produce results that can contribute to the next generation of chips for digital devices. As an intern at ARCNL, you will have the freedom to drive your own project and work closely with our team of around 80 researchers, fellow interns, and experienced supervisors. Also, ARCNL is a cohesive institute with a clear mission driving its research, making it an ideal place to kickstart your career in research and development. Visit our website or contact our group leaders directly to learn more about our internship opportunities and application requirements. Please find below a few of our internship vacancies. But, do not hesitate to contact a group leader directly since there are plenty of options that are not on the website.

In this project you will work on expanding our capabilities to perform optical metrology in the terahertz spectral range, by helping to design, build and apply a terahertz time-domain spectroscopy microscope. The microscope will use femtosecond lasers to generate and detect terahertz pulses using non-linear optical techniques. You will then apply the THz microscope to measure and understand the conductivity of 2D and 3D materials on the micrometer and nanometer scale. In one planned mode of operation the THz microscope will be used in combination with a camera, to take THz pictures with several micrometers spatial resolution in a single laser shot. The proposed work is part of a national (nano) metrology project, financed by a NXTGEN HIGHTECH Groeifonds grant.
