Hot-carrier-limited device lifetime of surface-channel p-MOSFETs is found to correlate well with gate current over a wide range of bias. The same result is not observed for buried-channel p-MOSFETs. A gate current model for surface-channel p-MOSFETs is presented. Using this gate current model, reasonable estimates of AC stress lifetime can be made based on DC stress data.
