Abstract
A ready for rotation state detection device is configured to detect a state in which a substrate, which is placed on a concave portion formed in a surface of a turntable, will not fly out of the concave portion when the turntable is rotated in a chamber. The ready for rotation state detection device includes a ready for rotation state detection unit configured to detect that a height of a surface of an end of the substrate is equal to or lower than a predetermined value indicating that the turntable is rotatable, upon receiving the substrate on the concave portion.
