An interface transport mechanism uses an upper hand when transporting a substrate from a substrate platform to an exposure device before exposure processing by an exposure device, and uses a lower hand when transporting the substrate from the exposure device to the substrate platform after the exposure processing by the exposure device. That is, the lower hand is used to transport a substrate to which a liquid is attached after exposure processing, and the upper hand is used to transport a substrate to which no liquid is attached before exposure processing.
