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

Impact and cohabitation of Lithium on a microelectronics platform
Contract
Thèse
Job description
Context: Lithium-based materials, whether thin layers or bulk material, are of great interest for varied applications (batteries, RF components…). However, their cohabitation with other “standard” materials for microelectronics requires special attention regarding dissemination in the clean room and a potential impact on electrical performances of devices. Indeed, as a precaution, these materials are “confined” on dedicated manufacturing lines, without full knowledge of their potential effect on the manufactured devices. This work aims at understanding the phenomena leading to lithium dissemination, to propose solutions to keep it under control and to take advantage of possible beneficial effects.
Mission: During this Ph.D. thesis, you will work in close collaboration with a multidisciplinary team in CEA and with their partners. This will involve highlighting the possible vectors of Lithium dissemination in common manufacturing spaces in clean rooms. Furthermore, you will define a methodology to identify and quantify Lithium in various materials and at their interfaces using physicochemical characterization tools available to the “Ion Beams” and “Operational Metal Contamination” (clean room) teams from the Surfaces & Interfaces Analysis Laboratory (LASI). A large part of the work will rely on ion beam analysis technics such as secondary ion mass spectrometry. This implementation will allow studying the mechanisms and kinetics of lithium diffusion as well as to evaluate its impact on the performance of “microelectronics” devices.
Profil: Chemist, physicist, engineer, etc., you have knowledge in chemistry/physics on materials/ semiconductors. Holder of a Bac+5, you are curious, rigorous, creative and wish to participate in a 3-year research project in support of microelectronics.
