    • PROBLEM TO BE SOLVED: To provide the method and device for forming the thin film of a composite metal compound capable of optionally regulating the refractive index at the time of forming an optical thin film. capable of film formation while the reaction of oxidizing, nitriding, fluoriding or the like is executed to an extra-thin film and capable of forming a metallic compd. thin film stable in optical characteristics, dynamical characteristics or the like at a high speed without increasing a substrate temp.
      SOLUTION: As for the method for forming the thin film of the composite metallic compd., respectively independent each target 29 and 49 composed of at least two kinds of different kinds of metal is sputtered, a stage in which an extra-thin film composed of composite metals or the imperfect reactant of the composite metals is formed on a substrate and a stage in which the formed extra-thin film is irradiated with the active seed of an electrically neutral reactive gas, the extra-thin film is brought to react with the active seed of the reactive gas and is converted into the compd. of the composite metals are successively repeated to form the compd. thin film of the composite metals with desired film thickness on the substrate.
