    Abstract: A method of manufacturing a semiconductor device is disclosed. The method provides a semiconductor substrate with at least a PMOS device and at least an NMOS device thereon. A first insulating layer is formed overlying the NMOS and PMOS devices. A second insulating layer is formed overlying the first insulating layer. The second insulating layer overlying the PMOS device is thinned to leave portion of the second insulating layer. A first thermal treatment is performed on the NMOS and PMOS devices. The second insulating layer overlying the NMOS device and the remaining portion of the second insulating layer overlying the PMOS device are removed and the first insulating layer overlying the NMOS and PMOS devices is thinned to leave a remaining portion thereof.

    Abstract: A metal gate/high-k dielectric semiconductor device provides an NMOS gate structure and a PMOS gate structure formed on a semiconductor substrate. The NMOS gate structure includes a high-k gate dielectric treated with a dopant impurity such as La and the high-k gate dielectric material of the PMOS gate structure is deficient of this dopant impurity and further includes a work function tuning layer over the high-k gate dielectric. A process for simultaneously forming the NMOS and PMOS gate structures includes forming the high-k gate dielectric material, and the work function tuning layer thereover, then selectively removing the work function tuning layer from the NMOS region and carrying out a plasma treatment to selectively dope the high-k gate dielectric material in the NMOS region with a dopant impurity while the high-k gate dielectric in the PMOS region is substantially free of the dopant impurity.
