Characterization of thin films with x-ray total reflection is introduced. Titanium silicite thin films are studied by grazing incidence x-ray diffraction. The epitaxial C49-TiSi2 grains are formed on heavily BF2 ion implanted Si (001) substrate after low temperature annealing, and they suppress the phase transition from C49 to C54 during high temperature annealing. SiO2 thin films are investigated by x-ray reflectivity analysis. Thermal oxides have always the high density interface layer of -1 nm in thickness. Extremely thin native oxides on Si is also characterized in a function of chemical cleaning solutions.
