The atmospheric pressure plasma enhanced chemical vapour deposition is one of hot topics in the field of plasma applications during last years especially due to considerably high growth rates and lower costs. This work deals with the deposition of silicon oxide from hexamethyldisiloxane (HMDSO) thin films using an atmospheric pressure plasma jet (APPJ) system in open air conditions. A sinusoidal high voltage with a frequency between 19-23 kHz at power up to 1000 W was applied between two tubular electrodes separated by a dielectric material. The main gas flow consisted of dry air which was introduced through the torch at a flow rate of 108 l/h. The jet, characterized by Tg ~600-800K, was mostly laminar (Re ~1200) at the nozzle exit and became partially turbulent along the torch axis (Re ~3300). The spatially resolved emission spectra showed OH, N2, N2+ and CN molecular bands and O, H, N, and Cr lines as well as the NO2 chemiluminescence continuum (450-800 nm). Thin films with good uniformity on the substrate were obtained at high deposition rate, between 800-1000 nm/s, and AFM results revealed that coatings are relatively smooth (Ra ~2 nm).
