Abstract:
A method for fabricating an integrated circuit device is disclosed. An exemplary method comprises performing a gate replacement process to form a gate structure, wherein the gate replacement process includes an annealing process; after the annealing process, removing portions of a dielectric material layer to form a contact opening, wherein a portion of the substrate is exposed; forming a silicide feature on the exposed portion of the substrate through the contact opening; and filling the contact opening to form a contact to the exposed portion of the substrate.
