Abstract :
The effects of hole trapping and de-trapping in lateral DMOS transistors under hot carrier stress are studied. It is shown that the stress sequence has an important effect on how degradation is induced in the device. Experimental evidence is provided that hot hole trapping in the device birds beak is a dynamic effect. A model is proposed
