A substrate processing apparatus includes a transfer block in which a transfer device configured to transfer a substrate is placed, and a processing block provided adjacent to the transfer block. The processing block includes a liquid film forming unit configured to form a liquid film on a top surface of the substrate which is held horizontally, and a drying unit configured to replace the liquid film with a supercritical fluid to dry the substrate. The drying unit includes a pressure vessel having therein a drying chamber for the substrate, a cover body configured to close an opening of the drying chamber, and a supporting body configured to support the substrate horizontally in the drying chamber. The supporting body is fixed to the drying chamber. The transfer device advances into the drying chamber through the opening of the drying chamber while holding horizontally the substrate having the liquid film thereon.
