    • PURPOSE:To efficiently synthesize a high hardness BN film of high quality on a substrate at a high speed by straightly arranging a means of evaporating a substance contg. boron, a plasma generating region, an ion beam accelerating region and the substrate in succession. CONSTITUTION:An evaporating means, a plasma generating region 17, an ion beam accelerating region 19 and a substrate 18 are straightly arranged in succession. By the evaporating means, an evaporating substance 16 contg. B such as metallic B put in a copper hearth 15 is evaporated by heating with thermoelectrons generated from a filament 3 and converged with a magnet coil 32. In the region 17, a gas 21 contg. N for forming ions is introduced into a plasma generating chamber 29 from a pipe 22 and dissociated into ions and electrons with a magnet coil 24. In the region 19, the ions are led to a reaction chamber 27 through a leading electrode 25 and accelerated with a lens 26. Ion beams and the evaporating substance 16 are irradiated without throwing a shadow on the substrate 18 to form a thin film contg. cubic BN and/or hexagonal close packed BN on the substrate 18. Thus, a high hardness BN film is obtd.
