Patent ID: 8877076

Claim:
A substrate treatment method for removing a resist from a substrate surface, the method comprising: a liquid film forming step of supplying a resist lift-off liquid at a predetermined flow rate onto a surface of a substrate held by a substrate holding unit, and rotating the substrate at a first rotation speed, whereby a liquid film of the resist lift-off liquid is formed covering the surface of the substrate; a liquid film retaining step of, after the liquid film forming step, rotating the substrate held by the substrate holding unit at a second rotation speed lower than the first rotation speed, whereby the resist lift-off liquid film formed on the surface of the substrate is retained on the surface of the substrate; a liquid film heating step of, simultaneously with the liquid film retaining step, locating a heater in opposed relation to the surface of the substrate held by the substrate holding unit and heating the resist lift-off liquid film retained on the major surface of the substrate by the heater; and a heater moving step of, simultaneously with the liquid film retaining step and the liquid film heating step, moving the heater along the surface of the substrate.
