The recent discovery of ferroelectricity in hafnium oxide (HfO2) thin films generates a strong interest for ultra-low power non volatile memories, in which the information is stored by the orientation of the electric dipoles in this material. Among those memories, the ferroelectric field effect transistor (FeFET) is quite appealing to combine logic and memory operations […] >>

In the history of semiconductors, the requirements in terms of device size have always followed a descending trend. Low thermal budget solutions are now key to manage these specifications. Within this context, nanosecond laser annealing stands as an excellent solution. Laser process conditions can be adjusted to the material structure. During heating and according to […] >>

Power electronics used in particular for the electric vehicle requires the fabrication of smaller and smaller devices able of sustaining high currents and high working voltages. The miniaturization of these components requires the development of new dielectric materials with high breakdown field. A promising approach is to combine the high dielectric constant of inorganic oxides […] >>

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 […] >>

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 […] >>
