The IMS Laboratory of Bordeaux develops
original and coherent research actions in
the domains of:
•
Modelling and elaboration of materials,
sensors and microsystems for the elec-
tronic devices; modelling, design, inte-
gration and reliability analysis of com-
ponents, circuits and assemblies;
•
Identification, command, signal pro-
cessing and images, supervision and
conduct of the complex and heteroge-
neous processes.
The fields of application of the laboratory
concern in particular transports and are
investigated through numerous European,
national or regional projects.
Key Research Fields and
Competence Areas:
Reliability:
•
Behavioral modelling based on physical
phenomena
•
Multi-physics approach: electrical,
thermal, physico-chemical, mechani-
cal, EMC
•

material, device and system
•
Identification and modelling of degra-
dation and failure mechanisms
•
Life time distribution modelling
Power semi-conductor devices:
•
Influence of thermal and mechanical
stresses on active devices
•
