Popis: | Silicon carbon nitride thin films were prepared by microwave ECR plasma enhanced unbalanced magnetron sputtering. Chemical structure, mechanical and optical properties of the films as a function of graphite target voltage has been studied. The chemical structure in the deposited film is investigated with Fourier transform infrared spectroscopy (FTIR). The Si–C–N bonds increased from 17.14% to 23.56% while the graphite target voltage changed from 450 V to 650 V. The composition of SiCN thin films was analyzed by X-ray photoemission spectroscopy (XPS). The optical property was measured with UV–visible spectrophotometer. It was found that the transmittance of SiCN thin films decreases with the increasing carbon content; the optical gap value progressively decreases from 2.65 to 1.95 eV as the carbon content changes from 19.7% to 26.4%. The hardness of the thin films has been studied by nano-indentation, it increased with the graphite target voltage. The maximum hardness of the thin films reaches 25 GPa. |
