Abstract:
1. A liquid processing method comprising: placing a plate to adjacently face at least one surface of a target substrate held in a horizontal state, and supplying a chemical liquid into a gap between the plate and the target substrate, thereby forming a chemical liquid film filling the gap in a vertical direction; subjecting the target substrate to a process using a state with the chemical liquid film thus formed, whereupon the liquid film is used; then supplying a rinsing liquid into the gap and replacing the chemical liquid film partly or entirely with the rinsing liquid, thereby forming a secondary liquid film filling the gap in a vertical direction; then supplying a gas to the secondary liquid film filling the gap in the vertical direction, thereby breaking the secondary liquid film; then expanding the gap in a vertical direction; then supplying the rinsing liquid onto said at least one surface of the target substrate while rotating the target substrate, thereby performing a rinsing process; and then performing throwing-off and drying by rotating the target substrate.
