Isothermal and isochronal annealing experiments on irradiated commercial power VDMOSFETs

Describes effects in two types of gamma-ray irradiated power VDMOSFETs, commercially available from different manufacturers. Isothermal annealing with constant and switching gate bias, as well as isochronal annealing have been performed. The application of charge-pumping measurements in commercial three-terminal VDMOSFETs is also discussed. Besides enabling insight into the post-irradiation response of investigated devices, obtained results point out some interesting post-irradiation phenomena.
