    • A method of fabricating a semiconductor device and a semiconductor device fabricated thereby. The method of fabricating the semiconductor device includes forming gate electrodes on a semiconductor substrate; forming source/drain regions within the semiconductor substrate so as to be located at both sides of each of the gate electrodes; forming a nickel silicide layer on surfaces of the gate electrodes and the source/drain regions by evaporating nickel or nickel alloy on the semiconductor substrate formed with the gate electrodes and the source/drain regions and then performing a thermal process on the nickel or the nickel alloy; forming an interlayer insulating layer, which is formed with contact holes through which a surface of the nickel silicide layer is exposed, on a surface obtained after the above processes have been performed; forming an ohmic layer by evaporating a refractory metal conformably along the contact holes, the refractory metal being converted to silicide at a temperature of 500° C. or more; forming a diffusion barrier on the ohmic layer conformably along the contact holes; and forming a metal layer by burying a metal material within the contact holes.
