Abstract

A removal liquid is supplied to a substrate on which a thin film formed is patterned by dry etching using a resist film as a mask, and cleaning is made with de-ionized water, thereby removing a reaction product generated on the surface of the substrate. After that, the processed substrate is heated, thereby completely drying the substrate from which the reaction product has been eliminated.
