摘要：
The effects of pre-irradiation bum-in stressing on post-irradiation annealing response of power VDMOSFETs have been investigated. Threshold voltage rapid increase above its pre-irradiation value (rebound effect) and mobility increase up to the value somewhat higher than the one after irradiation have been observed during post-irradiation annealing. These phenomena occured with certain delay in pre-irradiation stressed devices. The underlying changes of gate oxide-trapped charge and interface trap densities have been calculated and analysed in terms of the mechanisms responsible for pre-irradiation stress effects.
