Abstract: The present invention relates to an apparatus and a method for treating a substrate with liquid. The substrate treating apparatus comprises a substrate supporting unit for supporting the substrate, a liquid supply unit for supplying a liquid to the substrate supported on the substrate supporting unit, and a controller for controlling the liquid supply unit, wherein the liquid supply unit comprises a first nozzle for supplying a first liquid and a second nozzle for supplying a second liquid, and a second area where the second liquid is supplied on the substrate is provided within a first area where the first liquid is supplied on the substrate. The first liquid and the second liquid supplied with a hydrophobic film are discharged with different ways from each other. Thereby, particles with various sizes may be removed depending on each discharge methods.
