Multi plasma jet system with 4 independent nozzles working on the principle of surface-wave discharge (SWD) has been developed. The system was optimized and used for plasma-enhanced chemical vapor deposition (PECVD) of nominally pure and Al and Mn doped ZnO thin films. The surfatron source was powered by a microwave magnetron generator working at a frequency of 2.45 GHz with the output power of 300 W per surfatron. The time-resolved properties of low-pressure plasma jet working under deposition conditions in pulse mode were studied using Langmuir probe. It was found that the plasma density inside the active plasma jet is about 1017 m-3 and electron effective temperature can reach approximately 3 eV. The set of ZnO samples with a thickness of 300 nm were prepared on Si, ITO and quartz substrate and were analyzed by XRD, SEM, EDX, UV-light amperometry and optical ellipsometry. All samples under study were crystalline in nature, revealed n-type conductivity.
