Claim 8:
9. A system for fabricating a metal oxide semiconductor field effect transistor (MOSFET) device, comprising:
a transfer chamber defining a transfer space;
an n-type metal oxide semiconductor (NMOS) chamber, a p-type metal oxide semiconductor (PMOS) chamber, a pre-clean chamber, a metal-silicide deposition chamber, and a plasma chamber, wherein each of the NMOS chamber, the PMOS chamber, the pre-clean chamber, the metal-silicide deposition chamber, and the plasma chamber is coupled to the transfer chamber, and the NMOS and PMOS chambers are each source-drain epitaxy chambers;
a transfer robot in the transfer space configured to access the transfer chamber, the NMOS chamber, the PMOS chamber, the pre-clean chamber, the metal-silicide deposition chamber, and the plasma chamber;
a controller comprising instructions for device fabrication, wherein, when executed by a processor, the instructions cause the system to:
retrieve a substrate from the transfer chamber;
dispose the substrate in the NMOS chamber, the PMOS chamber, or the plasma chamber;
perform a pre-silicide treatment on the substrate, wherein the pre-silicide treatment comprises:
exposing the substrate to one or more precursor sources to form a doped surface of the substrate;

transfer the substrate into the metal-silicide deposition chamber; and
subsequent to performing the pre-silicide treatment on the substrate, form, by chemical vapor deposition, a metal-silicide layer on the treated substrate.
