|Abstract: ||This paper deals with the influence of the nitrogen flow rate on the microstructure of delta-TiN(x) films prepared by d.c, magnetron sputtering. The delta-TiN(x) films were prepared under decreasing nitrogen flow rates to obtain nitrogen contents in the films ranging from x = 0.99 to 0.95. Ion bombardment of the films was negligible in these experiments. Some films prepared under deposition conditions which typically result in a fine-grain (about 0.1 mum) transition zone microstructure exhibit a ''large''-grain (about 1 mum) zone III microstructure. It has been demonstrated that there exists a narrow area of nitrogen flow rate for which the microstructure of the films does not agree with the zone model. The large-grain films are stress free. The nitrogen content in the films containing large grains is x = 0.97. All deposition conditions except the nitrogen flow rate were kept constant in this experiment. Chemical energy dissipated during the reactive process can explain the observed effects.|
