Abstract:
Provided are a thin film formation apparatus, a sputtering cathode, and a method of forming thin film, capable of forming a multilayer optical film at a high film deposition rate on a large-sized substrate. The thin film formation apparatus forms a thin film of a metal compound on a substrate in a vacuum chamber by sputtering. The vacuum chamber is provided in its inside with targets composed of metal or a conductive metal compound, and an active species source for generating an active species of a reactive gas. The active species source is provided with gas sources for supplying the reactive gas, and an energy source for supplying energy into the vacuum chamber to excite the reactive gas to a plasma state. The energy source is provided between itself and the vacuum chamber with a dielectric window for supplying the energy into the vacuum chamber.

Claim (Index 1):
A method of forming a thin film comprising:\n a sputtering step for sputtering a target composed of metal or a conductive metal compound, the target being arranged to be opposed to a substrate, and by the sputtering, dispersing a particle that is not a complete compound from the target to the substrate in a vacuum chamber; and a composition conversion step for converting the particle to a complete metal compound in the vacuum chamber by providing a dielectric window for supplying the energy into the vacuum chamber that is arranged in parallel with the substrate, or in such a way as including towards the target side at an angle of less than 90\u00b0 to the substrate, and by contacting the particle with an active species of a reactive gas generated by an active species source for generating the active species of the reactive gas that is arranged to produce mutual electromagnetic and pressure interactions with the target, thereby forming a thin film composed of the complete metal compound on the substrate.
