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 2):
The method of forming a thin film according to  claim 1 , further comprising, after the composition conversion step, a film formation repetitive step where the sputtering step and the composition conversion step are repeated in parallel a plurality of times.
