Patent attributes
Processing chambers (3A-3F) for applying a process to a substrate W housed therein are provided at a periphery of a conveying chamber 2. A conveying case (4) houses the substrate (W) in a state isolated from an outside atmosphere. The conveyance case (4) has a gate valve (30) and a transfer mechanism (22). A conveying mechanism (5) supports the conveyance case 4, and carries the conveyance case (4) to a position for conveying in/conveying out a substrate. The number of processing chambers connectable to a conveying chamber is not limited, and conveyance to the processing chamber can be executed while maintaining a predetermined ambience for an atmosphere of a substrate that is to be processed.
