Abstract :
A method for rapidly evaluating the generation rate in the bulk of an MOS structure without requiring knowledge of the doping profile is described. The proposed technique is based on the measurement of two high frequency capacitance time transients after applying a depletion voltage step and a linear voltage ramp on the gate electrode which drives the device from depletion towards accumulation.<>
