Abstract
PURPOSE:To form a boron film with superior mechanical strength enough to prevent cracking, when separated from a metal substrate, by heat treating amorphous boron formed on the substrate to diffuse the boron into the substrate and by chemically vacuum-depositing beta-rhombohedral boron on the substrate. CONSTITUTION:A metal substrate such as a Ta wire set in a furnace core tube is heated to 800-1200 deg.C to deposit amorphous boron on the substrate according to reducing decomposition reaction of the following equation: 2BX3+2H2 2B+ 6HX3 (where X is a halogen element such as Cl, Br or I). The amorphous boron- deposited substrate is then heat treated at 1200-1800 deg.C to diffuse the boron into the substrate. On the boron-diffused substrate beta-rhombohedral boron is chemically vacuum-deposited at 1250-1400 deg.C to form a desired boron film.
