Super-Resolution Soft X-Ray Microscope based on Laser-produced plasma (Elsene, BE) en VUB Brussels University | Vrije Universiteit Brussel

1 - Working at the VUB

For more than 50 years, the Vrije Universiteit Brussel has stood for freedom, equality and solidarity, and this is very much alive on our campuses among students and staff alike. 

At the VUB, you will find a diverse collection of personalities: innovators pur sang, but above all people who are 100% their authentic selves. With some 4,000 employees, we are the largest Dutch-speaking employer, in the private sector, in Brussels; an international city with which we are only too happy to connect and where (around) our 4 campuses are located. 

Add to this our principle of free research - in which self-reflection, a critical attitude and an open, creative mind around scientific and social issues are central - and you have a university that is fundamentally groundbreaking and pioneering in education and research. In short: the VUB all over again. 

Moreover, the VUB is a member of EUTOPIA, an alliance of like-minded European universities, all ready to reinvent themselves.

2 - Position description

The Faculty of Engineering, Department Elektronica en informatica, Research Group Electronics and Informatics: Research – Development - Innovation is looking for a PhD-student with a doctoral grant. 

More concretely your work package, for the preparation of a doctorate, contains: 

Explore and advance state-of-the-art optical technologies for semiconductor and biomedical applications

The Department of Electronics and Informatics (ETRO), an imec research group at the Vrije Universiteit Brussel (VUB), has an open research position for a talented and motivated researcher.

Project

In optical chip metrology and health diagnostics, conventional microscopes face increasing challenges in achieving nanometer-scale resolution, as industrial demands push for patterns with ever-smaller critical dimensions. There is also a growing need for non-destructive, sub-100 nm resolution metrology techniques suitable for wide-field imaging, particularly given the increasing structural complexity and the introduction of new materials in semiconductor and biomedical applications.

In soft X-ray imaging systems, performance is limited because conventional optics do not function effectively. To address this, we employ diffraction- and reflection-based optics to achieve the highest efficiency. This project explores soft X-ray radiation based on laser-produced plasma, innovative optical system designs, and applications that extend beyond ultraviolet, hard X-ray, and EUV technologies. The research focuses on developing cost-effective and versatile solutions, with an emphasis on both the radiation source and optical components. The ultimate goal is to expand the range of semiconductor inspection and healthcare imaging applications.

Who we are: A university research group at imec-VUB in Brussels, with expertise in optical imaging systems and signal processing

Responsibilities:

• Design of optical setup
• Optical system analysis and simulation
• Material characterization
• Developing AI/ML algorithms
• Literature review and preparation of journal publications
   

Type of work: 40% setup and experiments, 40% modeling/simulation, 20% literature review and design

For this function, our Brussels Humanities, Sciences & Engineering Campus (Elsene) will serve as your home base. 

3 - Profile

What do we expect from you?

• Master’s degree in Photonics, Electronics, Physics, or Computer Science  

Required background: Engineering Technology, Optical Engineering, Computer Engineering

• You have not performed any works in the execution of a mandate as an assistant, paid from operating resources, over a total (cumulated) period of more than 12 months.

• As a (non-)EEA national, meet the conditions for obtaining a valid permit for VUB and comply with the VUB residence requirements. More info here.

The VUB wants to be a reflection of the society where everyone's talent is valued, regardless of gender, age, religion, skin color, migration background, disability and neurodiversity.

4 - Offer

Are you going to be our new colleague?
