The IEEE, the largest international professional association devoted to electricity and electronics, has recognized the achievements of Olivier Faynot, the Director of CEA-Leti's Silicon Components Department, for his exceptional achievements with advanced CMOS components.
CEA-Leti's cornerstone research on silicon carbide substrates initially gained traction in 2019 with Soitec on booming demand from the electric vehicle market and a scarcity of monocrystalline silicon. Today, with four presentations at ICSCRM 2023 showcasing pioneering advances in transferred silicon carbide substrates for electronics and photonics, CEA-Leti continues to lead the way in silicon carbide and thin film transfer technologies.

CEA-Leti combined its hardware and software expertise to investigate the benefits of new signal processing approaches to conventional Time-of-Flight (ToF) histogram acquisition schemes. Among the techniques developed are compressive sensing and expectation-maximization algorithms. Both turned out to be promising avenues for reducing hardware design constraints in active direct ToF 3D imaging based on SPAD pixels.
A specialist in ultra-miniature rechargeable batteries for medical devices, the startup is acquiring an industrial site 15 km from CEA-Leti. It will ultimately employ 50 people. Volume manufacturing is to begin late 2026.
Developing new methods to extract encrypted data from cell phones and assist with criminality or terrorism matters: such was the purpose of the European ExFiles project, which was under the technical coordination of CEA-Leti from 2020 to 2023. The European Commission described the results as ‘very positive’.
CEA-Leti and the startup Kineis recently developed ultra-miniaturized antennas that significantly improve communication between earth-based objects and satellites. These improvements include lower power consumption and costs, improved reception of messages and an insensitivity to an equipment’s orientation. These advances open the door to low-cost radio links that could be accessible around the globe.
Epitaxy has become a key process in the development of devices that rely on substrates. While epitaxy refers to the general ability to grow crystals or deposit a material on a substrate, there are numerous types of epitaxy, which each have their own fields of application. Expertise at CEA-Leti covers a wide range of applications, including recent work on Nitride Epitaxy, particularly adapted to power or radio-frequency transistors as well as micro-LEDs.
Four years after launch, the CEA-Leti start-up Wormsensing has invested in a production line capable of manufacturing two million vibration sensors per year. Enough to win volume orders from customers in the energy, automotive, healthcare and manufacturing sectors.
On-chip batteries will play a key role in our increasingly connected, electrified, and sustainable world. As wireless sensor technologies improve and the Internet of Things expands, the need for tiny, high-energy-density solid-state integrated batteries for a rapidly-growing number of use cases is urgent. CEA-Leti is pushing back the frontiers of on-device energy storage with innovative battery performance optimization tools.
After earning a Materials Engineering diploma from INSA Lyon, Jules Tillement did a final internship in a research laboratory specializing in image sensors. He was then recruited to pursue a doctorate at STMicroelectronics, in partnership with CEA-Leti.
When operated at high frequencies, certain piezoelectric materials display exceptional quality factors and power densities. CEA-Leti and an academic research partner have been investigating how to bring these remarkable properties to power conversion in the form of a new inductor-free power converter concept based on mechanical, rather than magnetic, energy storage.
Late 2023, CEA-Leti executed a real-scale validation of private 5G network elements capable of offering a data rate of at least 20 Mbps at a 30 km distance. Intended for port operations, it could be adapted to other uses when public networks fail to achieve the required performance.
A new European Union consortium created to accelerate the development of next-generation, edge-AI technologies is installing cleanroom tools and gearing up to design, evaluate, test and fabricate new circuits from across Europe.
CEA-Leti and STMicroelectronics made advances on an insulated recessed-gate GaN (gallium nitride) power transistor that will improve device reliability.
