Abstract:
A substrate processing method includes a processing liquid supplying step of supplying a processing liquid having a solute and a solvent to a front surface of a substrate, a processing film forming step of forming on the front surface of the substrate a processing film which holds a removal object present on the front surface of the substrate by solidifying or curing the processing liquid supplied to the front surface of the substrate, and a peeling step of peeling the processing film from the front surface of the substrate together with the removal object by supplying a peeling liquid to the front surface of the substrate, and the peeling step includes a penetrating hole forming step of forming a penetrating hole on the processing film by dissolving partially the processing film in the peeling liquid.
