Abstract :
The paper presents results of a study of post-irradiation 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
