Abstract :
The effects of pre-irradiation positive gate bias stress on radiation response of power VDMOSFETs have been investigated. Larger irradiation induced threshold voltage shift and mobility reduction in stressed devices have been observed, clearly demonstrating inapplicability of gate bias stressing for radiation hardening of power VDMOSFETs
