Abstract
A substrate processing apparatus includes a transfer chamber row of transfer chambers arranged linearly, a processing chamber row of processing chambers arranged on one side or both sides of the transfer chamber row, a driving mechanism for rotating/extending/contracting a transfer arm of a substrate transfer mechanism in each transfer chamber, and a controller. A center of a substrate supporting region in the processing chamber is positioned closer to the transfer chamber row than a line connecting a rotation axis of the transfer arm and a center of a gate valve. Further, when loading and unloading a substrate between the processing chamber and the adjacent transfer chamber, the controller controls the driving mechanism such that a center of the substrate held by the transfer arm passes along an outer side of a line that connects a rotation axis of the transfer arm and a center of a substrate supporting region.
