Abstract
In a processing of immersing substrates in a chemical solution, and agitating the chemical solution by as bubbles or liquid, the gas bubbles or liquid is supplied so as to bring about alternate occurrence of a first state and a second state. The first state is a state in which an amount of the gas bubbles or the liquid supplied to first side in one direction of each substrate is greater than an amount of the gas bubbles or the liquid supplied to a second side in the one direction of the substrate. The second state is a state in which the amount of the gas bubbles or the liquid supplied to the first side in the one direction of the substrate is smaller than the amount of the gas bubbles or the liquid supplied to the second side in the one direction of the substrate.
