Abstract

A method of resist-processing a rectangular substrate including a resist coating step of supplying resist solution to the substrate, while rotating it, to form resist film at least on one surface of it and a resist removing step of jetting removing liquid, which can solve resist, to both surfaces of it at its side peripheral portions to remove the resist film from them.
