Patent ID: 7687861

Claim:
A semiconductor device formed on a substrate, the semiconductor device comprising: an NMOS transistor having a first gate electrode and first source/drain regions formed in the substrate on opposing sides of the first gate electrode, the NMOS transistor having a plurality of spacers formed alongside the first gate electrode, the first source/drain regions having a first silicided region; and a PMOS transistor having a second gate electrode and second source/drain regions formed in the substrate on opposing sides of the second gate electrode, the PMOS transistor having fewer spacers formed alongside the second gate electrode than the NMOS transistor, the second source/drain regions having a second silicided region, wherein every diffusion region of the first source/drain regions is a substantially equal distance from the first gate electrode as a corresponding diffusion region of the second source/drain regions is from the second gate electrode, wherein the substrate, the first source/drain regions, and the second source/drain regions have the same composition.
