Abstract:
A substrate processing method includes a liquid film forming step of forming a liquid film of the low surface tension liquid, an opening-forming step of forming an opening in the center region of the liquid film, a liquid film removal step of removing the liquid film from the upper surface of the substrate by widening the opening, a low surface tension liquid supply step of supplying a low surface tension liquid toward a first liquid landing point which is set on the outside of the opening, a hydrophobic agent supply step of supplying a hydrophobic agent toward a second liquid landing point which is set on the outside of the opening and further from the opening than the first liquid landing point, and a liquid landing point moving step of moving the first liquid landing point and the second liquid landing point so as to follow widening of the opening.
