The parameters of silicide films (layer thickness, uniformity, phase transition, etc.) obtained using nondestructive tools are compared using traditional analytical techniques including four-point probe, X-ray diffraction, and cross-sectional transmission electron microscopy. Properties of thin TiSi2 films prepared by an advanced one-step annealing process featured by direct step silicidation with enhanced transition has been compared with that obtained from a conventional two-step annealing process. This process produces thin TiSi2 films with improved surface roughness without causing the agglomeration and uncompleted phase transition failure. Optical properties such as refractive indexes, reflectivity, and dielectric constants of the thin TiSi2 films as obtained from spectroscopic ellipsometer measurements are reported in the wavelength range 0.25-0.90 mu m.enellipsometrymetallic thin filmsnondestructive testingtransmission electron microscopyx-ray diffraction670620530541journal article
