TECHNICAL EXPERTISE

Engineering

Electronics, microelectronics

The main mission of the Microelectronics Department (SEM) is to meet the needs of physics experiments and projects by designing and characterizing systems in the field of analog/mixed discrete or microintegrated front end electronics (ASIC), power electronics and radio frequency

In order to carry out this mission, the SEM works in close collaboration with the other technical departments and maintains a permanent technology watch, participates in the construction of demonstrators and prototypes, carries out tests and characterizations.

In recent years, the activity of the service has been mainly marked by a strong involvement in the following projects : SuperNEMO, SPIRAL2, FRACAS, Id-LISE, SPES; the growing demand of physicists for RFQs; the progress of R&D in charge preamplifiers; the complexity of new ASICs. This activity has enabled the creation or strengthening of collaborations with other laboratories at IN2P3 (GANIL, LAL, LPSC) or abroad (Manchester University, INFN Legnaro).

On a more ad hoc basis, the SEM provides developments within the framework of industrial contracts (example: CERAP/Atron Metrology).

Agents of the SEM are members of the microelectronics/electronics network and participate in the transversal projects Cherenkov Lab and DiamASIC.
