Abstract
A method of forming a semiconductor substrate (and resultant structure), includes providing a semiconductor substrate to be silicided including a source and drain formed therein on respective sides of a gate, depositing a metal film over the gate, source and drain regions, reacting the metal film with Si at a first predetermined temperature, to form a metal-silicon alloy, etching the unreacted metal, depositing a silicon film over the source drain and gate regions, annealing the substrate at a second predetermined temperature, to form a metal-Si alloy, and selectively etching the unreacted Si.
