Copper nitride thin films were deposited on glass substrates by reactive DC magnetron sputtering at various N2-gas flow rates and different substrate temperature. X-ray diffraction measurements show that the films are composed of Cu3N crystallites with anti-ReO3structure and exhibit preferential orientation to the [111] and [100]. The preferred crystalline orientation of the films changes with the N2-gas flow rate and substrate temperature. The N2-gas flow rate and the substrate temperature not only affect the crystal structure of films but also affect the deposition rate, the resistivity and the microhardness of the Cu3N films.

Al thin films were prepared over different substrates at various process conditions using DC sputtering. The surface topography of all prepared films was examined using AFM technique. Very smooth, uniform and dense surface were observed for Al films coated over Glass substrates. The observed particle size was nano scale (20 -70 nm) for Glass substrates. Sputtering power showed immense effect on surface roughness with respective to Ar gas flow rate. Noticeable change on surface with large particles was observed in Copper substrates at various sputtering power and gas flow rate.

Al-doped zinc-oxide (AZO) thin films were prepared by RF magnetron sputtering at different oxygen partial pressures and substrate temperatures. The charge-carrier concentrations in the films decreased from 1.69 × 1021to 6.16 × 1017 cm−3with increased gas flow rate from 7 to 21 sccm. The X-ray diffraction (XRD) patterns show that the (002)/(103) peak-intensity ratio decreased as the gas flow rate increased, which was related to the increase of AZO thin film disorder. X-ray photoelectron spectra (XPS) of the O1s were decomposed into metal oxide component (peak A) and the adsorbed molecular oxygen on thin films (peak B). The area ratio of XPS peaks (A/B) was clearly related to the stoichiometry of AZO films; that is, the higher value of A/B showed the higher stoichiometric properties.

This study discusses the mechanical and tribological properties of a series of carbon nitride coatings deposited by unbalanced DC magnetron sputtering using nitrogen-argon mixture gas and graphite targets. The carbon nitride coatings were with varying carbon/nitrogen ratio by varying the gas flow rate ratio of nitrogen gas/argon while kept the overall gas flow rate at constant. The carbon nitride coatings with C/N ratios from 2.01 to 3.27 were obtained. The coatings were characterized and studied by nanohardness, scratching, and wear testers. It was found that the carbon nitride coatings with C/N ratio=2.36 showed the best performance of all the evaluated properties.
