摘要：

Time dependent dielectric breakdown and bias temperature instability of HfO2 devices with polysilicon gate electrode have been studied. Both N and PMOS capacitors have sufficient TDDB lifetime, whereas PMOS capacitors show gradual increase in the leakage current during stress. HfO2 PMOSFET's without nitridation have sufficient immunity against negative bias temperature instability. Bias temperature instability for NMOS can be a potential scaling limit for HfO2.
