High k gate
Web1 de fev. de 2015 · Metal gate/high-k stack will still be the only solution for channel current control in the transistors. However, the equivalent oxide thickness (EOT) of the high-k gate dielectric has to be scaled down to half nanometer range. We may prefer even aggressive thinning of the gate dielectric in order to suppress the “off current” more effectively. WebSiO2 as the gate dielectric, as early as 1980, one of the authors proposed the use of high-k dielectrics as the gate dielectric material.4 Figure 1 shows the influence of thickness and dielectric constant on the threshold voltage of a MOSFET at submicron channel lengths. As can be seen from Fig. 1, the use of high-k dielectric provides less ...
