A substrate processing method of drying a substrate by using a processing fluid in a supercritical state is performed by a substrate processing apparatus. The substrate processing apparatus includes a fluid discharge unit, a supply line, a fluid drain unit, a drain line and a flow control device. The substrate processing method includes: flowing the processing fluid from the fluid discharge unit to the fluid drain unit such that the processing fluid flows along a surface of the substrate. The flowing of the processing fluid includes flowing the processing fluid in a first flow mode and flowing the processing fluid in a second flow mode. Between the first flow mode and the second flow mode, a flow direction distribution of the processing fluid is different, and a switchover between the first flow mode and the second flow mode is performed by the flow control device.
