Claim 3:
4. A substrate processing method, comprising:
holding multiple substrates by supporting the multiple substrates with a vertical standing posture from below;
immersing the multiple substrates in a processing liquid stored in a processing tub by lowering the multiple substrates from a standby position above the processing tub to a processing position within the processing tub; and
supplying a gas into the processing tub in which the processing liquid is stored,
wherein the supplying of the gas comprises:
before the multiple substrates are immersed in the processing liquid stored in the processing tub,

a) decreasing a flow rate of the gas to be supplied into the processing tub; and
after the multiple substrates are immersed in the processing liquid, which has been determined that the multiple substrates have been allowed to be immersed in the processing, and the multiple substrates reach the processing position,

b) increasing the flow rate of the gas to be supplied into the processing tub such that the multiple substrates are to be processed.
