Abstract:
1. A film deposition method for depositing a film on a substrate by carrying out a cycle of supplying in turn at least two kinds of reaction gases that react with each other to the substrate to produce a layer of a reaction product in a chamber, the film deposition method comprising steps of: substantially horizontally placing the substrate on a turntable in a chamber; supplying a first reaction gas from a first reaction gas supplying portion to a surface of the turntable, the surface having a substrate receiving area in which the substrate is placed; supplying a second reaction gas to the surface of the turntable from a second reaction gas supplying portion arranged away from the first reaction gas supplying portion along a circumferential direction of the turntable; supplying a first separation gas from a separation gas supplying portion provided in a separation area located between a first process area in which the first reaction gas is supplied and a second process area in which the second reaction gas is supplied, in order to separate atmospheres of the first process area and the second process area, heating the first separation gas supplied to the separation gas supplying portion; rotating the turntable in the circumferential direction relative to the first process area, the second process area, and the separation area while the first reaction gas, the second reaction gas, and the first separation gas are supplied to the turntable in order to deposit a film on the substrate; and evacuating the first reaction gas, the second reaction gas, and the first separation gas supplied to the turntable through an evacuation opening.
