In this work, we combine our recently developed recovery free on-the-fly interface traps measurement (OFIT) and fast-pulsed-measurement (FPM) to conduct a comprehensive study of BTI degradations for both n- and p-MOSFETs with SiON gate dielectric. The results provide the most reliable data for the understanding and modeling of BTI degradation and also provide new insights to re-access the impact of...
The physical and electrical characteristics of high-k (HK) gate dielectric HfLaO were systematically investigated. Incorporation of La in HfO2 can raise the film crystallization temperature from 400degC to 900degC. Moreover, NMOSFETs fabricated with HfLaO gate dielectric exhibit superior electrical performances in terms of threshold voltage (Vth), bias temperature instability (BTI), channel electron...
In this work, lanthanum-incorporated refractory metal nitride is investigated as an n-type metal gate electrode with tunable work function. By adding La into HfN metal gate deposited on SiO2 gate dielectric, its gate work function can be tuned from 4.6 eV to 3.9 eV continuously by changing La composition. The authors also report the effective work function of TaN can be tuned to p-type with the incorporation...
In this work, by using a novel HfLaO high-kappa (HK) gate dielectric, we show for the first time that with a thermal budget of 1000 degC, Fermi-Pinning in the HK-metal gate (MG) stack can be released. The effective metal work function (EWF) can be tuned by a wide range more than the requirement of bulk CMOSFETs, and also fits the future UTB-SOI CMOSFETs when Si body thickness is approaching 3 nm or...
