摘要:
A sputtering apparatus includes a target holder which is placed in a vacuum vessel and can hold a target configured to deposit a film on a substrate, a substrate holder which can mount the substrate, a first shield member which is disposed in a vicinity of the substrate holder, and configured to form a closed state in which the substrate holder and the target holder are shielded from each other, or an open state in which the substrate holder and the target holder are opened to each other, a first opening/closing driving unit adapted to open/close the first shield member to enter the open state or the closed state, a second shield member, having an annular-shaped, disposed on the surface of the substrate holder and an outer peripheral portion of the substrate, and a driving unit adapted to move the substrate holder in order to bring the substrate holder, on which the second shield member is disposed, close to the first shield member in the closed state. The first shield member has at least one annular-shaped, first protruding portion formed on it to extend in the direction of the second shield member. The second shield member has at least one annular-shaped, second protruding portion formed on it to extend in the direction of the first shield member. The first protruding portion and the second protruding portion fit together in a non-contact state at the position up to which the driving unit brings the substrate holder close to the first shield member.
