20080271988 | Thin Film Forming Sputtering Target, Dielectric Thin Film, Optical Disc and Production Method Therefor - Diffusion of water or oxygen present in the dielectric protection film is restrained by eliminating free oxygen in an oxide thin film while maintaining the characteristics of a dielectric protection film. As the dielectric material for forming a dielectric protection film for an optical disc or the like, an oxide mixture thin film of a niobium oxide and one of a silicon oxide and a titanium oxide is used. In a preferable example, a target made of a niobium oxide as the main component with 1 to 30% by weight of a silicon oxide added is used for formation of an oxide thin film by sputtering. Moreover, the oxide thin film is formed preferably in a nitrogen atmosphere. A nitrogen containing oxide thin film is produced by carrying out sputtering using a target with the oxygen lacked and a minute amount of nitrogen added. Thereby, a thin film having little reducing function and a high barrier property while having the characteristics comparable to a complete oxide can be produced. | 11-06-2008 |
