Method of film deposition on substrate surface and substrate produced by the method |
摘要 |
A method of film deposition is disclosed, which eliminates the conventional problem that a coating film having a component concentration gradient in the thickness direction and thus having a boundary with a compositional gradient or a coating film in which two or more components coexist as a mixture thereof cannot be stably obtained by sputtering. In the method, two planar cathodes are closely arranged as a pair, and a voltage is applied thereto while alternately inverting the polarities thereof so that when a target A bonded to one of the cathodes is used as a negative electrode, then a target B bonded to the other cathode and differing to the target A in component is used as a positive electrode. The targets A and B are simultaneously bombarded with positive ions while passing a substrate in front of the targets so as to cross the cathodes. Thus, a coating film having a boundary with a compositional gradient in the thickness direction or a coating film having a two-layer structure composed of a layer of ingredient A and a layer of ingredient B is deposited by sputtering through one-direction conveyance.
