Abstract

The defect generation rate (P_g) during constant voltage stress is investigated by using short-time voltage pulses over large fluence range. It is found that P_g is not constant as a function of injected charge and the voltage acceleration of P_g in the linear defect generation regime is similar to that of the reciprocal of QBD. The change of carrier capture cross (sigma) during defect generation was speculated as one of the reasons responsible for the change of P_g value. However, from this preliminary report, we have determined that the change of P_g can not be explained by the change of sigma.
