Abstract
NBTI of HfO2 and SiO2 devices are studied and compared. The pulsed stress frequency responses of DVth and acceleration parameters are quite different for them. Bulk traps in the HfO2 film are used to explain these differences. Furthermore, caution must be taken when extrapolating the device lifetime of HfO2 devices.Proceedings Title
