The cluster has been developing a range of experimental skills and techniques for over 30 years. These skills are applied to a wide variety of passive (antennas, MEMS, etc.) and active microwave components (nanodevices, HBT on InP, HEMT AsGa, InP, HEMT GaN and metamorphic AsGa, MOSFET Si, etc.). But also, on more complex devices integrating functionalities (MMICs, low noise amplifier, fast sampler...).
Areas of expertise :
The CHOP Division ISO8 certified includes over 900m2 the common means of the IEMN allowing the characterisation of the main electrical parameters of electronic components and sub-systems over a wide range of frequencies.
Most measurement benches are modular to meet research needs as effectively as possible. The division's engineers develop the benches with a view to continuous improvement to keep pace with technological innovations.
The cluster enables vector or scalar electrical characterisation of ultra-fast devices, transistors, circuits, MEMS, etc.
- From DC to THz frequencies
- Temperature (cryogenic, ambient, 500 K measurements)
- Under laser or solar illumination
- Coplanar sub-terminals (on-wafer), coaxial or free space
- In non-linear mode
Coupled with near-field or spectroscopic techniques, it is possible to characterise :
- 2D materials
- Micro-nano components
- Gases, liquids, solids
Some experiments have been designed to electrically test components under 'harsh' conditions, such as at low temperature (5.5K) or even at high voltage (10kV).
Expertise in characterisation of ultra-fast devices is internationally recognised and enables the cluster to play a very important role in the joint laboratories (ST Microelectronics) and various partners (THALES, CEA,... ) and miscellaneous regional, national or foreign research centres.
