Abstract
PURPOSE: To prepare the titled glass having extremely hard surface and usable for a long period forming little scratch, by evaporating carbon while irradiating the cover glass with inert gas ion in vacuum.
CONSTITUTION: The substance to be evaporated is placed on the evaporation source 3 and evaporated in vacuum toward the substrate by the energy irradiation from an electron beam source, laser beam source, or an inert gas ion beam source such as Ar gas. The evaporation source 3 is provided with a number of fine diamond particles or a graphite block. Simultaneous with the arrival of the evaporated substance to the substrate, the substrate is irradiated with inert gas ion beam such as He, Ne, Ar, Xe, etc., emitted from the inert gas ion source 4. By this procedure, a diamond thin film is deposited on the surface of the substrate, i.e. a cover glass, held with the substrate holder 2.
