Are you enthusiastic about exploring scientific challenges with an industrial application perspective?
Extreme ultraviolet lithography (EUVL) is the latest generation of the semiconductor manufacturing technology powered by laser-produced-plasma light sources. These EUV light sources emit in a broad range of wavelengths spanning from soft x-rays to visible. A quantitative spectral characterization capability of such a broad wavelength range recently become available using a proprietary transmission grating spectrometer developed by XUV optics group (https: // doi.org/10.1063/5.0073839). The calibration of the charge-coupled- device (CCD) that are used as detectors in such a spectrometer is sensitive to the operation conditions of the light source. Cross-calibration of the CCD with other type of detectors such as photodiodes and investigating the light sources with time resolution provides wealth of information that is otherwise not accessible.
We are looking for a motivated and skilled post-doctoral researcher to carry out research on the fundamental physics questions on the calibration sensitivity and time-dependent spectral evolution of the EUV light source. Methods to enable inline calibration and time-resolved operation is to be developed in the project with the support of technical staff. Specifically, aim is to design multilayer spectral filters based on Bragg's condition and deposition these designs using magnetron sputtering to enable cross- calibration of the CCD response and the photodiode response.
The XUV Optics Group at Twente has started a new multidisciplinary research program on these topics. We develop forefront fundamental research, relevant to high tech applications (www. utwente.nl/xuv/). The research will take place in a state-of-the-art thin film laboratory within the MESA+ Institute for Nanotechnology at the University of Twente, in collaboration with various academic and industrial partners. The XUV group has a track record in developing thin film physics and holds several records in functional film properties, including the reflectivity of thin film multilayer optics.
Your goal is to develop the fundamental physics understanding on time-resolved and calibrated spectroscopy of EUV light sources. This includes:
