AbstractAC-stress-induced degradation in metal-oxide-semiconductor field-effect transistor (MOSFET) with N2O-grown and N2O-nitrided gate oxides was investigated, with emphasis on the duty cycle and voltage swing of the gate pulse. It is demonstrated that N2O-oxide devices show a weaker duty-cycle dependence than thermal-oxide devices, with N2O-nitrided oxide superior to N2O-grown oxide. More significantly, opposite frequency dependence of the VT shift is found between gate-pulse swings of 0-1/2 VD and 0-VD. The reasons are likely due to charge trapping and neutral-trap creation in the gate oxide. © 1998 Elsevier Science Ltd. All rights reserved.
