The breakdown of thin oxides due to dc stressing and unipolarity and bipolarity dynamic stressing has been compared. For dynamic stressing, the total integrated charge-to-breakdown, Q//B//D, depend on both the pulse width and duty cycle of the stressing voltage. Unipolarity and bipolarity stressing produce similar results. In all cases, both Q//B//D and t//B//D of dynamic stressing are greater than those of dc stressing. For 0. 1-ms pulses, Q//B//D and t//B//D are about four times larger than what dc stressing would predict. The main reason for the higher Q//B//D and t//B//D under dynamic stressing is reduced hole trapping at localized weak oxide areas. A transient hole generation and relaxation model is proposed to quantitatively explain the increase in Q//B//D for dynamic stressing.
