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 […] >>

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 […] >>

Over the past 20 years, wireless communication systems have continued to evolve and offer new services. Today, the success is such that the frequency bands below 10GHz are saturated and we are now turning to millimeter band frequencies. These frequencies offer the possibility to develop systems with higher data rates. However, they require beamforming to […] >>

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 […] >>
