Popis: | Process of silicon-carbonitride (SiCN) film production from a new volatile organosilicon, N-bromhexamethyldisilazane, is developed. The use of this chemical comprising the relatively week N-Br bond makes it possible to increase the film growth velocity in the plasma-chemical process with remote plasma in comparison with the processed in which hexamethyldisilazane and hexamethylcyclotrisilazane are used. The chemical composition of the films is determined using a complex of spectroscopic methods. It is found that inorganic SiCN films containing Si-N, Si-C, and C-N bonds are deposited at temperatures 570–870 K. The C-N bonds are formed already at a temperature of about 470 K. It is shown that the use of this volatile organosilicon material makes it possible to synthesize silicon carbonitrides with various ratios of the Si-C, Si-C, and C-N bonds. This enriches the possibilities of producing films and coatings with various functional parameters. The nanohardness of 100-nm films prepared at T > 770 K is 17 GPa. |
