The cassette housing chambers 30A and 30B are connected to the process chambers 26A through 26D via a transfer chamber 28. In the transfer chamber 28, there are provided a first transfer unit 32 for delivering the object W between the cassette housing chambers 30A and 30B and the transfer chambers 26A through 26D, and a second transfer unit 34 for delivering the object W between the process chambers 20A through 26D and the transfer chamber 28. In the overlapping range 36 of transfer ranges of the first and second transfer units 32 and 34, an aligning unit 38 for aligning the object W is arranged.
