A film deposition apparatus for depositing a thin film on a substrate by feeding at least two kinds of reaction gases in a vacuum chamber includes a turntable; a substrate placement part on the turntable; a first and a second reaction gas feed part provided apart from each other to feed a first and a second reaction gas into a first and a second process region, respectively, on the turntable; a separation region positioned between the first and second process regions and including a first separation gas feed part to feed a first separation gas and a ceiling surface; a center part region positioned inside the vacuum chamber and including an ejection opening for ejecting a second separation gas; an evacuation port; and a drive part to rotate the turntable so that the substrate passes through the first and second process regions at different angular velocities of the turntable. |
