ABSTRACT:
A film deposition apparatus for depositing a film on a substrate by performing a cycle of alternately supplying at least two kinds of reaction gases that react with each other on the substrate to produce a layer of a reaction product in a vacuum chamber is disclosed. The film deposition apparatus includes a ring-shaped locking member that may be provided in or around a wafer receiving portion of a turntable in which the substrate is placed, in order to keep the substrate in the substrate receiving portion.
