Abstract

Abstract PURPOSE: To form a hydrophilic resist film without effecting the concentration of a developer by forming a hydrophilic film consisting of a neutral substance before the surface of the resist film applied onto a bode to be treated is developed and treated. CONSTITUTION: A neutral and hydrophilic liquid stored in a tank 62 is fed through a nozzle 60 from the upper section of a body to be treated W supported under a horizontal state by a spin chuck 26. A PVA aqueous solution (an aqueous polyvinyl alcohol solution) having viscosity of less than 10cp, favorably 2-3cp or an aqueous saccharose solution is used as the liquid. Accordingly, the upper section of a resist film A is supplied with a fixed quantity of the neutral and hydrophilic liquid on the top face of the body to be treated W under a stationary state. The liquid is spread on the top face of the body to be treated W, the whole surface of the resist film A, by centrifugal force, thus forming a hydrophilic film B.
