摘要:
A semiconductor device is described. That semiconductor device comprises a high-k gate dielectric layer that is formed over a channel that is positioned within a substrate, and a metal gate electrode that is formed on the high-k gate dielectric layer. The high-k gate dielectric layer has off-state leakage characteristics that are superior to those of a silicon dioxide based gate dielectric, and on-state mobility characteristics that are superior to those of a high-k gate dielectric that comprises an isotropic material.
