The Power Devices Electrical Characterization Laboratory covers the main needs of the Power Devices and Systems research group of IMB-CNM in terms of electrical assessment of the power devices developed in the Clean Room. In addition, it is also open for industrial and/or academic collaborations such as the characterization of commercial devices under specific conditions not provided in datasheets.
The main activities performed in the Power Devices Electrical Characterization Laboratory are:
- Electrical validation of new power devices developed in the Clean Room.
- Electrical analysis of commercial power devices.
- Development of new techniques for electrical characterization.
- Development of integrated power systems.
- Steady-state electrical characterization of power devices at different temperatures:
- Voltage-Current curves (forward and blocking)
- Electrical parameters extraction (on-resistance, threshold voltage, etc.).
- Capacitance-Voltage curves
- Calibration of temperature sensitive parameters (up to 400ºC)
- On-wafer mapping with semi-automatic probe stations
- Dynamic electrical characterization of power devices at different temperatures:
- Switching tests and dynamic parameters extraction (turn-on and turn-off times, switching losses, etc.).
- Reliability/ruggedness testing of power devices:
