Patent ID: 7001086

Claim:
A substrate treating method comprising: discharging a first solution continuously to a substrate from a first solution discharge port disposed at the bottom a first solution discharge/suction unit, sucking the solution on the substrate continuously from two suction ports disposed at the bottom the first solution discharge/suction unit so as to enclose the solution discharge port, and treating the substrate surface with the first solution while moving the first solution discharge/suction unit and the substrate relatively in a horizontal linear motion; and discharging a second solution different from the first solution continuously to the substrate from a second solution discharge port disposed at the bottom a second solution discharge/suction unit different from the first solution discharge/suction unit, sucking the solution on the substrate continuously from two suction ports disposed at the bottom the second solution discharge/suction unit so as to enclose the solution discharge port, and treating the substrate surface with the second solution while moving the second solution discharge/suction unit and the substrate relatively in a horizontal linear motion.
