Claim Text:
1. A substrate treatment method for treating a front surface of a substrate formed with a predetermined pattern, the method comprising: a liquid film forming step of forming a liquid film of a treatment liquid on the front surface of the substrate; a hydrophobization liquid supplying step of supplying a hydrophobization liquid to a center portion of the front surface of the substrate for hydrophobizing the front surface of the substrate, while rotating the substrate; an inactivation suppressing step of suppressing inactivation of the supplied hydrophobization liquid on a peripheral edge portion of the front surface of the substrate simultaneously with the hydrophobization liquid supplying step; and a drying step of drying the substrate to which the hydrophobization liquid has been supplied, wherein the inactivation suppressing step includes a heating step of heating at least one of the substrate and the hydrophobization liquid supplied to the front surface of the substrate, wherein at least one of a center portion of the substrate and the hydrophobization liquid supplied to the center portion of the front surface of the substrate is heated with a smaller heat amount per unit area than a peripheral edge portion of the substrate and a hydrophobization liquid supplied to the peripheral edge portion of the front surface of the substrate in the heating step.
