SUBSTRATE PROCESSING APPARATUS AND SUBSTRATE PROCESSING METHOD

A substrate processing apparatus includes: a loading/unloading block; a processing station provided on one of left and right sides of the loading/unloading block; a relay block provided on one of left and right sides of the processing station; processing blocks provided side by side in a left-right direction to form the processing station, each of the processing blocks including a processing module configured to perform a process on the substrate and a main transfer mechanism configured to deliver the substrate to the processing module; and bypass transfer mechanisms provided separately from the main transfer mechanism and provided respectively for the processing blocks arranged side by side in the left-right direction to transfer the substrate between left and right blocks, wherein bypass transfer paths for the substrate transferred by the plurality of bypass transfer mechanisms have heights different from each other, and partially overlap each other in a plan view.
