Abstract :
For the first time, the degradation of a DMOS transistor is shown to be due to hot hole injection in the drift region field oxide. The saturation effects observed in the parameter shifts are reproduced by a new degradation model using the bulk current as the driving force. A very good agreement with experimental data is obtained for various stressing conditions.
