Abstract

See full text

A substrate treatment method is provided, which includes a rinsing step of supplying a rinse liquid to a front surface of a rotating substrate after a chemical liquid step. The rinsing step includes a higher-speed rinsing step and a deceleration rinsing step to be performed after the higher-speed rinsing step. The deceleration rinsing step includes a liquid puddling step of reducing the rotation speed of the substrate within a rotation speed range lower than a rotation speed employed in the higher-speed rinsing step and supplying the rinse liquid to the front surface of the substrate at a flow rate higher than a maximum supply flow rate employed in the higher-speed rinsing step, whereby a puddle-like rinse liquid film is formed on the front surface of the substrate.
