General information
Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Job title
Instrumental development for low-energy critical dimension small angle x-ray scattering H/F
Subject
This Postdoc will take place at the CEA–LETI, a major European actor in the semiconductor industry, at the Nanocharacterization platform of the CEA–LETI which offer world-class analytical techniques and state-of-the-art instruments.
In this project, we are looking to extend the metrology with x-rays (CD-SAXS) leveraging the recent breakthrough in the development of low-energy x-ray sources (A. Lhuillier et al. 1988, Nobel prize 2023) called High Harmonics Generation (HHG) sources.
Therefore, you will participate in the development of a new and promising characterization methods called Low-energy critical dimension small angle x-ray scattering. The first set of measurements showed very promising results. The goal of this postdoctoral position is to continue the experimental testing through measurements campaigns at Attolab in CEA-Saclay and to advance understanding of the experimental data through modeling.
Contract duration (months)
1 year, renewable for 1 additional year
Job description
Your mission will focus on several aspects to explore in parallel:
- Develop the experimental set-up to enable Low-Energy SAXS measurements on Attolab's set-up (through punctual mission (2 or 3 times a year for 1 to 2 weeks) at Attolab in CEA-Saclay, Paris);
- Optimize and develop the experimental procedure to improve the data quality collected in November 2023;
- Measure new samples from CEA clean room to study defects inherent to the lithographic process such as overlay;
- Interact and work with a PhD student focusing on the data modeling to understand the acquired data and explore the limitation of the Low Energy SAXS technique;
- Define the specifications required from the source to meet the requirements from the industry.
Applicant Profile
We are looking for a candidate with a PhD in either physics, scientific instrumentation. Knowledge and experience with HHG sources are a plus but not critical. Knowledge of programing languages such as Python (and with finite element simulations specifically) would be also valuable.
