Parameters of radiation-induced centers for simulation of irradiated power devices

Abstract

Irradiation techniques are widely used for carrier lifetime control, especially in power devices, because of their good reproducibility. Simulation of these devices is however lacking due to missing or incomplete recombination center data, despite the availability of suitable recombination models. In this work, we used center data estimated by DLTS and lifetime measurements for the simulation of electron radiated devices and compare the results with the measured device characteristics.
