The SmartCut technology is nowdays widely used on the manufacture of innovative substrates such as SOI (Silicon-on-Insulator). The fundamental physical phenomena underlying this process are still being actively studied. In particular, the catastrophic fracture step, which allows the transfer of a very thin layer of a donor substrate onto a base or receiver substrate. An […] >>

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 […] >>

This thesis concerns the field of HgCdTe infrared detectors for astrophysical applications, for which the Infrared Laboratory of CEA -Leti is a world leader. The student will join the infrared laboratory which includes the entire detector manufacturing process. He will produce the samples using the technological means of elaboration available in the Leti clean room. […] >>

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 […] >>
