Experimental verification of the usefulness of the nth power law MOSFET model under hot carrier wearout

In this paper the usefulness of the nth power law MOSFET model under Hot Carrier Injection (HCI) wearout has been experimentally demonstrated. In order to do that, three types of nFET transistors have been analyzed under different HCI conditions and the nth power law MOSFET model has been extracted for each sample. The results show that the model can reproduce the MOSFET behavior under HCI wearout mechanism. Therefore, the impact of HCI on circuits can be analyzed by using the nth power law MOSFET model.
