Rapid advances in resistive oxide memory (OxRAM) could soon put the technology on manufacturers' production lines.
Silicon photonics—integrated optical circuits on silicon substrates—first emerged around 20 years ago. Since then, the now-crucial technology has gained traction on growing demand for very-high-speed fiber optic communications. Scientists at CEA-Leti are pushing silicon photonics to new limits to bring data centers and supercomputers the terabit/s capabilities they need.
CEA-Leti has developed a new spectrometric imaging detector that can clearly distinguish breast tumor tissue from healthy tissue in mice at a glance.
Tiempo Secure, a secure semiconductor design company, has been selected, in a partnership with the CEA, as a winner of the Great Cybersecurity Challenge ("Grand Défi Cyber"), a project launched by the French government in 2020. The announced objective of the Great Cybersecurity Challenge is to make our systems sustainably resilient to cyberattacks. Participating in the Challenge brings a valuable support to Tiempo Secure for the development of the iMRC project, which makes IoT connected objects resistant to known and yet unknown attacks.
In research for the European Space Agency’s Artes+ MONAMI project, Kinéis and CEA-Leti are developing the next generation of miniature hybrid terrestrial/satellite antennas for IoT sensors.
CEA-Leti unveils its 2020 Silicon Components Division report highlighting the latest advances for silicon devices and technologies.
CEA-Leti has developed an innovative optical sensor called μPMSense that can detect finer particles than today’s commercially available sensors. The new device can even identify non-organic, metal, and carbon-based particles that today’s products cannot pick up at all.
III-V semiconductor materials are expensive and increasingly rare. Their replacement as the go-to material for lasers is inevitable. CEA-Leti researchers were part of an international team* that recently published a notable advance in Nature Photonics. They developed an optically-pumped IV-IV semiconductor device capable of producing a 2.5 micron laser beam with an ultra-low threshold at temperatures of 100 K.
As the number of IoT devices increases, so does the number of spent batteries that have to be dealt with. Making battery lifespans longer is one of the responses to this major environmental and societal challenge. The CEA Tech institutes are developing technologies and contributing to research and development projects to do just that.
GRENOBLE, France – Sept. 13, 2021 – In an ambitious and urgent proposal to improve energy efficiency in new microelectronic hardware and systems by a factor of 1,000 by 2030, CEA-Leti has challenged the ICT industry, especially in Europe, to collaboratively tackle the data deluge with greener electronics.
In the future, quantum devices cooled to 10 mK will be used together with conventional electronics. Which raises the question of how well CMOS components, designed to operate at ambient temperature, hold up in temperatures close to absolute zero. To test out this scenario, researchers from Irig and CEA-Leti made hybrid circuits with the two technologies.
Semi-conductors are everywhere, omnipresent in our computers, telephones, cars and smart objects, concentrating some of the world's best innovations. CEA-Leti engineers are stepping up their efforts to support the strong demand for innovation, notably in the medical industry.
CEA-Leti is coordinating the European MeM-Scales project, which kicked off in early April. The focus? Neuromorphic chips capable of learning on several time scales.
Optically-coupled photonic chips cannot currently be tested at wafer level. Instead, they must be cut, packaged, and then tested individually.
Within CEA Tech and CEA-Leti, activities of the Optics and Photonics division cover most of the largest industrial markets for photonics:
All-wavelength imaging (Gamma and X rays, visible, infrared, THz)
Optical data communications
Optical environmental and 3D sensors
The R&D projects are carried out with both industrial and academic partners. The industrial partners of the Optics and Photonics division range from local SMEs to overseas and global companies.
Our developments merge fundamental physical aspects with advanced technological developments, they interweave nano-sciences, optics, micro-electronics, advanced nano-fabrication, integration and packaging, while taking into account system requirements.
Optics and Photonics division employs 345 persons overall, 235 permanent R&D engineers and technicians, 43 CEA experts and 45 PhD students and post docs. 74 patents filed in 2020 and 700 patents in portfolio
Theoretically, in-memory computing should make it possible to reduce circuit power consumption. Researchers recently verified this hypothesis in the lab, using tools they developed for the programming of innovative computing architectures.
Satellite NB-IoT communications could prove useful wherever terrestrial base stations are lacking, such as in sparsely-populated rural areas and in the oceans, for example.
GRENOBLE, France – July 1st – CEA-Leti, a technology research institute of CEA, today announced that Sebastien Dauvé has been named CEO, succeeding Emmanuel Sabonnadiere.
Sebastien Dauvé was named Director of CEA-Leti effective on July 1, 2021, after more than twenty years of experience in microelectronics technologies and their applications, including clean mobility, medicine of the future, and cybersecurity.
on the Minatec Campus, the System Division gathers over 300 high level researchers and engineers. This division is at the strategic core of CEA-Leti’s technological innovation and aims to provide a global and valuable “system perspective” on technological trends.
Our’s expertise is based on four major pillars which are (i) wireless communications, (ii) innovative sensor-system design, (iii) power management and electronics for energy and (iv) security solutions for electronic systems and components. Its teams are using tools and know-hows inherited from the physics, electromagnetism and electronic areas as well as from the signal and data processing domains; additionally, they have access to state-of-the-art facilities for the simulation, characterization and prototyping of complex electronic systems.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
