Dipole Model Explaining High-k/Metal Gate Threshold Voltage Tuning Conference Paper uri icon


  • An interface dipole model explaining threshold voltage (Vt) tuning in HfSiON gated n-channel field effect transistors (nFETs) is proposed. The magnitude of nFET Vt tuning tuning depends on rare earth (RE) type and diffusion in Si/SiOx/HfSiON/REOx cap layer/metal gated nFETs as follows: Sr < Er
