Laboratory for Analysis and Architecture of Systems
The “New devices” team of the ISGE group has experience of more than ten years in design, manufacturing, characterization and modelling of power devices and integrated systems. Its activities were mainly focused on devices and systems using silicon as the basic semiconductor material, which is used in a wide majority of power applications because of its low cost and its mature technology. Thus, in order to improve the performances of these power devices (increase in reverse voltage capability, frequency and temperature operations, reduction of conduction and switching losses) and, in particular, to overcome the limits of performance of the conventional unipolar power devices, the team invented new power devices architectures in silicon technology. One can quote, for example:
This works were based on the physical phenomena understanding specific to power devices. These studies required competences in these fields:
A large part of these works was carried out within the framework of collaborations with companies, in particular within the framework of laboratories common PEARL2 (with ALSTOM), the LCIP1, the LCIP2 and the LISPA (with in the past Motorola, from now on Freescale Semiconducteurs).
