摘要： A minute multilayer film with good characteristics is automatically and continuously formed on an in-line basis at a low production cost. In a sputtering chamber, there is provided a bonded target in which a first Ti member, a first Si member, a second Ti member, a Ta member, and a second Si member are bonded and which acts as a cathode electrode. A power is supplied between a substrate and the bonded target, and a substrate and a substrate holder are moved. With the movement, the substrate successively comes to face the first Ti member, first Si member, second Ti member, Ta member, and second Si member of the bonded target and sputtering is carried out on the substrate. A multilayer thin film of a structure consisting of a TiO2 film, an SiO2 film, a TiO2 film, a Ta2O5 film, and an SiO2 film is formed on a surface of the substrate. The thickness of each layer is adjusted by a film thickness correcting plate interposed between the substrate and the bonded target.
