Abstract

A substrate processing method includes a replacing step of replacing the processing liquid with a low surface tension liquid, a liquid film forming step of forming a liquid film of the low surface tension liquid on the upper surface of the substrate, by continuing supplying the low surface tension liquid to the upper surface of the substrate after the replacing step, an opening forming step of forming an opening at a central region of the liquid film, an enlarging removing step of removing the liquid film from the upper surface of the substrate by enlarging the opening toward a peripheral edge of the substrate, and a liquid film contact step of bringing a proximity member into contact with the liquid film, by bringing the proximity member close to the peripheral edge of the substrate after starting the opening forming step.
