  • Publication number: 20100227059
    Abstract: A film is deposited to a predetermined thickness on a wafer by allowing the wafer placed on a susceptor to alternately move through plural process areas where corresponding plural reaction gases are supplied from corresponding plural reaction gas supplying portions and a separation area where a separation gas is supplied from a separation gas supplying portion in order to separate the plural reaction gases. Such movement is achieved by rotating the susceptor relative to the plural reaction gas supplying portions and the separation gas supplying portion, or rotating the plural reaction gas supplying portions and the separation gas supplying portion relative to the susceptor. Then, when the film is deposited in the above manner to a predetermined thickness, the film deposition is temporarily stopped; the wafer is rotated around its center; and the film is deposited to another predetermined thickness in the same manner.
