Instrumental development for low-energy critical dimension small angle x-ray scattering H/F

CEA; Grenoble; Sur place; EUR 40 000 - 80 000; Plein temps

Résumé du poste

Une entreprise innovante recherche un postdoctorant pour développer une méthode de caractérisation prometteuse appelée SAXS à faible énergie. Ce rôle implique la création d'un dispositif expérimental et l'optimisation des procédures pour améliorer la qualité des données. Vous travaillerez en étroite collaboration avec des étudiants en doctorat pour modéliser les données acquises et comprendre les limites de la technique. En rejoignant cette équipe dynamique, vous aurez l'occasion de contribuer à des projets de pointe dans l'industrie des semi-conducteurs et d'explorer de nouvelles frontières dans la métrologie. Si vous êtes passionné par la recherche et le développement d'instruments, cette opportunité est faite pour vous.

Qualifications

• PhD requis en instrumentation scientifique avec une expérience en sources HHG.
• Connaissance des langages de programmation comme Python est un plus.

Responsabilités

• Développer un dispositif expérimental pour des mesures SAXS à faible énergie.
• Optimiser les procédures expérimentales pour améliorer la qualité des données.
• Mesurer de nouveaux échantillons pour étudier les défauts lithographiques.

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, and more precisely, at the Nanocharacterization platform of the CEA–LETI which offers world-class analytical techniques and state-of-the-art instruments. Our team aims to accompany the industry in the development of new characterization tools to meet the metrological needs of future technological nodes. Over the past few years, pioneering developments on a new metrology technique based on hard x-ray scattering called CD-SAXS were done at the PFNC. In this project, we are looking to extend the CD-SAXS approach 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 method called Low-energy critical dimension small angle x-ray scattering.

Your mission will focus on several aspects to explore in parallel:

1. Develop the experimental set-up to enable Low-Energy SAXS measurements on Attolab’s set-up (through punctual mission at Attolab in Paris/Saclay);
2. Optimize and develop the experimental procedure to improve the data quality collected in November 2023;
3. Measure new samples from CEA clean room to study defects inherent to the lithographic process such as overlay;
4. Interact and work with a PhD student focusing on the data modeling to understand the acquired data and explore the limitations of the Low Energy SAXS technique;
5. Define the specifications required from the source to meet the requirements from the industry.

We are looking for a candidate with a PhD in scientific instrumentation. Knowledge and experience with HHG sources would be beneficial. Knowledge of programming languages such as Python would also be valuable.

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 16,000 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.
