  author={Chuanzhao Yu and J. S. Yuan and J. S. Suehle},
  journal={IEEE Transactions on Electron Devices},
Channel hot-carrier-induced dc and RF performance degradations in 60-nm high-k nMOSFETs are examined experimentally. RF performances such as the cutoff frequency, noise figure, linearity, and flicker noise of high-k MOSFETs show significant vulnerability to the hot-electron effect. Analytical equations for normalized RF degradations relating to the device dc and ac parameters are derived. Good agreement between the analytical predictions and experimental data is obtained. The accuracy of the… CONTINUE READING
