Claim 18:
19. The CMOS transistor of claim 14, wherein:
a first source/drain contact physically contacts one of the p-type epitaxial source/drains of the PMOS transistor and a second source/drain contact physically contacts one of the n-type epitaxial source/drains of the NMOS transistor; and
the first source/drain contact and the second source/drain contact extend along the longitudinal direction of the common gate, the first source/drain contact does not extend over more than one recessed n-type silicon germanium projection from the silicon substrate, and the second source/drain contact does not extend over more than one recessed p-type silicon projection from the silicon substrate.
