摘要： An NMOS transistor may be formed with a biaxially strained silicon upper layer having a thickness of greater than 500 Angstroms. The resulting NMOS transistor may have good performance and may exhibit reduced self-heating. A PMOS transistor may be formed with both a biaxially and uniaxially strained silicon germanium layer. A source substrate bias applied to both NMOS and PMOS transistors can enhance their performance.

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.

摘要： Strained channel field effect transistors may have a threshold voltage shift. This threshold voltage shift may be compensated for by adjusting channel doping. But this also adversely affects mobility. The threshold voltage shift may be compensated, without adversely affecting mobility, by tailoring the workfunction of a metal gate electrode used in the transistor to adequately compensate for that threshold voltage shift. For example, in some embodiments, an appropriate metal may be selected with a slightly higher workfunction or, in other cases, the workfunction of a selected metal may be adjusted by, for example, doping the metal gate electrode with a material which increases the workfunction of the gate electrode.
