Abstract:
1. A film deposition method of forming a first thin film of a reaction product of a first reaction gas and a second reaction gas on a substrate, performed in a film deposition apparatus including, a turntable rotatably provided in a vacuum chamber and having plural mounting portions on each of which a substrate is to be mounted, a first gas supplying portion to supply a reaction gas to a first process area on the surface of the turntable, a second gas supplying portion to supply a reaction gas to a second process area which is apart from the first process area along a circumferential direction on the surface of the turntable, and a separation gas supplying portion to supply a separation gas to separation areas provided between the first process area and the second process area on the surface of the turntable, the method comprising: an adsorption step of adsorbing the first reaction gas onto the substrate by supplying the first reaction gas from the first gas supplying portion for a predetermined period without supplying a reaction gas from the second gas supplying portion while separating the first process area and the second process area by supplying the separation gas from the separation gas supplying portion and rotating the turntable; and a reaction step of having the first reaction gas adsorbed onto the substrate react with the second reaction gas by supplying the second reaction gas from the second gas supplying portion for a predetermined period without supplying a reaction gas from the first gas supplying portion while separating the first process area and the second process area by supplying the separation gas from the separation gas supplying portion and rotating the turntable.
