Developing method, substrate treating method, and substrate treating apparatus
First Claim
1. A substrate treating method comprising discharging a solution continuously to a substrate to be treated from a solution discharge port of a solution discharge/suction unit, sucking the solution on the substrate continuously from two suction ports disposed in the solution discharge/suction unit so as to enclose the solution discharge port, and treating the substrate surface with the solution while moving the solution discharge/suction unit and the substrate relatively in a horizontal linear motion,wherein the flow speed of the solution flowing between the substrate and the solution discharge/suction unit is faster than the relative moving speed between the solution discharge/suction unit and the substrate.

Abstract
A developing method comprises determining in advance the relation of resist dissolution concentration in a developing solution and resist dissolution speed by the developing solution, estimating in advance the resist dissolution concentration where the resist dissolution speed is a desired speed or more from the relation, and developing in a state in which the resist dissolution concentration in the developing solution is the estimated dissolution concentration or less.
