Abstract:
1. A semiconductor device manufacturing method comprising the steps of: conducting a wet treatment using organic peeling liquid or cleaning liquid on a substrate having an insulating film formed thereon and then forming a resist pattern on the insulating film, wherein before a resist serving as the resist pattern or antireflection coating provided between the insulating film and the resist is coated subsequently to the wet treatment, an organic solvent pre-treatment for removing reaction inhibiting materials which are contained in the organic peeling liquid or the cleaning liquid and inhibit the chemical reaction of the resist is conducted, wherein the organic solvent pre-treatment uses an organic solvent containing any one of polypyreneglycol monomethyl ether acetate, polypyreneglycol monomethyl ether, ethyl lactate, cyclohexanone and methyl ethyl ketone.
