Abstract
The article reports on the aspects of reactive deposition ultra-thin TiOx films (50 nm) by means of dual magnetron system with mirror and closed magnetic field (B field) configurations. The hysteresis effect of electrical discharge characteristics and oxygen partial pressure P(O2) are presented. The dual magnetron with closed B field configuration has less hysteresis peculiarities and transits back to metallic deposition mode at higher O2 flow rate (Q). The deposition rates don’t depend on B field configuration and correlate with changing of P(O2) and discharge voltage. The refractive spectra and energy of band gap, which are measured by UV-visible spectrophotometry and ellipsometry (λ=632.8 nm) methods, have strong dependence on Q(O2).
