Resonant antenna sensors for harsh environments
Microsystems sensors (MEMS) are the interface between the physical world and the digital world, and they are present today in most components and systems. A major challenge is the development of sensors that can be interrogated remotely, without electronic circuits or batteries, which will make it possible to envisage new applications as for example in […] >>

Development of innovative etching processes for the integration of ferroelectric materials in non-volatile memories
Today, memories are once again a priority for two reasons: data production is growing exponentially. Data storage and transfer consumes up to 90% of the energy in computing systems. Non-volatile memories, which retain information when not powered, are needed to limit energy consumption. Ferroelectric memories (FeRAM or FRAM) are one of the emerging non-volatile memory […] >>

Large scale parametric characterization, variability study and tests of quantum devices at cryogenic temperatures
A natural way to address the scalability of quantum devices is to design and realise arrays of individual quantum objects with nearest-neighbor interaction. In large-scale semiconductor quantum processors, a quantum bit is encoded in the spin of an isolated electron, trapped in an array of quantum dots (QDs) [1]. Over the years, we have studied […] >>

RF Cryo-CMOS/Superconductor circuits co-design
Quantum computing is nowadays a strong field of research at CEA-LETI and in numerous institutes and companies around the world. The Quantum Silicon Grenoble project, including CEA-LETI, CEA-IRIG and Néel Institut, aims to achieve a quantum computer based on quantum bits (qubits) in silicon. The operating conditions of qubits (cryogenic temperatures = 1K, high frequencies […] >>
