Each of the plurality of seating members includes: a pedestal member including a seating portion on which the substrate is seated and a magnet disposed at a position different from the seating portion, and supported by the pusher body such that the position of the magnet is moved according to seating or leaving of the substrate; a seating sensor configured to detect movement of the magnet; and a magnetic member disposed to shield a portion between a movable region of the magnet and the seating sensor.

Disclosed is a method for processing a substrate, comprising a liquid processing step of performing liquid processing on the substrate by supplying a processing liquid onto the substrate in a liquid processing chamber, a transfer step of transferring the substrate from the liquid processing chamber to a drying chamber, and a drying step of drying the substrate in the drying chamber. In the drying step, the substrate is dried while an edge region of the substrate other than a central region of the substrate is supported by a support unit, and in the liquid processing step, the liquid processing is performed on the substrate such that a height of the processing liquid remaining on the edge region of the substrate is greater than a height of the processing liquid remaining on the central region of the substrate when the liquid processing is completed in the liquid processing chamber.
