THIN-FILM FORMATION METHOD, THIN-FILM FORMATION DEVICE, OBJECT TO BE TREATED HAVING COATING FILM FORMED THEREON, DIE AND TOOL
[Problem] To provide a means for forming a thin-film in a desired part of an object to be treated. [Solution] The thin-film formation means according to the present invention is part of a thin-film formation method which supplies electricity to a raw-material gas in a reduced pressure container, converting the raw-material gas to plasma, and irradiates the plasma, thus forming a thin-film on the surface of an object to be treated. Therein, the effect of a magnetic field generated by a magnetic field generating means is used to form the thin-film in a desired part. The effect of the magnetic field focuses the flux of the plasma in a desired part of the surface of the object to be treated, thus enabling the thin-film to be formed in the desired part.
