Sputtering System

Tantalum oxide (Ta2O5) thin films, 100 nm thick were deposited by D.C. reactive magnetron sputtering system at different operated pressure on unheated p-type silicon (100) wafer and 304 stainless substrates. Their crystalline structure, film surface morphology and optical properties, as well as anticorrosive behavior, were investigated. The structure and morphology of films were characterized by grazing-incidence X-ray diffraction (GIXRD) and atomic force microscopy (AFM). The optical properties were determined by spectroscopic ellipsometry (SE). The corrosion performances of the films were investigated through potentiostat and immersion tests in 1 M NaCl solutions. The results showed that as-deposited Ta2O5 thin films were amorphous. The refractive index varied from 2.06 to 2.17 (at 550 nm) with increasing operated pressure. The corrosion rate of Ta2O5 thin film improves as the operated pressure decreases. The Ta2O5 thin films deposited at 3 mTorr operated pressure could be exhibited high performance anticorrosive behavior.

Dc Reactive Magnetron Sputtering

Titanium dioxide (TiO2) thin films have been deposited on Si-wafer and glass slide by DC reactive magnetron sputtering technique at different O2 gas flow rates. The crystal structure was characterized by grazing-incidence X-ray diffraction (GIXRD), surface morphology was analyzed by atomic force microscopy (AFM) and disinfection of surfaces by photo catalytic oxidation with TiO2 and UV light irradiation. The results showed that, from GIXRD results, all as-deposited TiO2 films have crystal structure of TiO2 corresponding to the A(101) and A(200). AFM results showed that the film thicknesses increase from 183 nm to 238 nm with increasing of O2 gas flow rate, while the film roughness was in range of 4.8 nm to 5.9 nm. The as-deposited anatase TiO2 thin film in this work can kill the bacteria when expose to the UV light.
