ABSTRACT:
A CMOS device includes high k gate dielectric materials. A PMOS device includes a gate that is implanted with an n-type dopant. The NMOS device may be doped with either an n-type or a p-type dopant. The work function of the CMOS device is set by the material selection of the gate dielectric materials. A polysilicon depletion effect is reduced or avoided.
