15 High-frequency magnetron sputtering facility Experiments Experiments are performed on a synthesis of metal, oxide and nitride coatings used as targets for incident ion beams and in ion-implantation doping. A technology has been developed and used for the preparation of ZnO 0,2 0,6 µm thick films on sapphire substrates by high-frequency reactive sputtering of a Zn target. The film exhibit one peak (002) in XRD spectra and 85 % transparency in the 0,2 0,6 µm spectrum range. The films have the grain size of ~60 nm and surface roughness 5 nm.
