摘要
The effective work function (EWF) of ternary metal-aluminum-nitride (M-Al-N, M=Ta, Ti, Mo, W) metal gate electrodes in high-k dielectric gate stacks has been investigated. With the addition of Al, the EWF can be tuned toward p-type (similar to 5eV) by 250meV compared to the EWF of the binary metal nitride. Low threshold voltage (V,) of similar to -0.35V, an equivalent oxide thickness (EOT)similar to 1.2nm, and performance suitable for gate-first 32nm low standby power applications are demonstrated.
