Abstract :
The behaviour of the threshold voltage in commercial n-channel power VDMOSFETs during biased thermal annealing, following /spl gamma/-ray radiation exposure, is investigated. It is found that ´rebound´ effect, observed in transistors irradiated and annealed with positive gate bias, is mainly due to the ´latent´ interface-trap generation. Possible mechanism for latent interface-trap buildup is proposed.
