Abstract

The properties of tin oxide films deposited at room temperature by dual ion beam sputtering (DIBS) using Sn targets and oxygen ion-beam have been examined as a function of oxygen ion energy. Studies by X-ray diffraction (XRD) showed that, with increasing oxygen ion-beam energy, the amorphous microstructure transformed into a crystalline SnO2 phase and the preferred orientations varied from (211), (101) to (002) on Si(100). Together with X-ray photoelectron spectroscopy (XPS), the Rutherford back-scattering (RBS) analyses revealed that, with an increase of oxygen ion-beam energy, the oxygen content and the packing density of the films increased slightly up to a value close to the stoichiometry of SnO2. These results indicate that crystalline SnO2 films can be synthesized at room temperature using DIBS with Sn target and oxygen ion-beam and also that the energetic oxygen ion-beams affect the phase formation, crystalline structure and the preferred orientation of the films.
