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

Description de l'unité
CEA is a major player in research, serving citizens, the economy, and the State.
It provides concrete solutions to their needs in four main areas: energy transition, digital transition, technologies for future medicine, and defense and security — all built on a foundation of fundamental research.
For over 75 years, CEA has been committed to supporting the scientific, technological, and industrial sovereignty of France and Europe, working toward a more secure and better-controlled present and future.
Located at the heart of regions equipped with major research infrastructures, CEA benefits from a wide network of academic and industrial partners in France, across Europe, and internationally.
CEA's 20,000 employees share three core values:
• A strong sense of responsibility
• Cooperation
• Curiosity

Contract
Internship
Job title
Stage - Exploring the Reliability of FDSOI Transistors in Cryogenic Environments
Subject
Join CEA Leti to develop electronics operating at extremely low temperature (down to 4K and below!), used in future quantum computer or spatial radio astronomy applications This internship provides an opportunity to improve our understanding of reliability physics at cryogenic temperature, and to offer a reliability-aware design platform for FDSOI technology in those extreme environments.
Contract duration (months)
6
Job description
As an intern at CEA, you will have the opportunity to work in a world-renowned research environment.
Our teams are made up of passionate and dedicated experts, providing a stimulating setting for learning and collaboration.
You will have access to cutting-edge equipment and top-tier research resources to successfully carry out your assignments.
Context
In recent years, the race to build a quantum computer has intensified, drawing widespread efforts. Such quantum computers operate at very low temperatures, well below 4K, to preserve the essential properties of quantum states. The use of conventional electronic circuits at cryogenic temperatures, in close proximity to the quantum processor, is necessary to control and detect quantum states more quickly and efficiently, while limiting the wiring to
ambient temperature instrumentation [1,2]. Other emerging applications requires low–temperature operation of CMOS transistors, such as spatial applications, high performance computing, high energy physics…, with a temperature of operation below 100K.
Work expected
In this internship you will perform electrical characterization and modeling of 28nm FDSOI (Fully-Depleted Silicon-On-Insulator [3]) transistors in cryogenic environment, advancing the understanding of reliability physics, and optimizing their potential down to deep cryogenic temperature.
