Abstract

A method for forming a molecular film includes the steps of: coating a surface of a substrate having active hydrogen atoms on its surface with a coating solution containing a silane-based compound having at least one reactive group selected from the group consisting of a chloro group, an alkoxy group and an isocyanate group; and effecting an elimination reaction between the active hydrogen atoms on the surface of the substrate and reactive groups of the silane-based compound, thereby covalently bonding the silane-based compounds to the surface of the substrate. The substrate is supplied to a chamber in which an atmosphere is maintained at a low water vapor density. The surface of the substrate is coated with a coating solution containing the silane-based compound and a solvent by using a transfer element. A dehydrochlorination reaction is effected between the active hydrogen atoms and the chloro groups of the silane-based compounds. Thereafter, any coating solution containing unreacted silane-based compounds after coating is removed inside or outside the chamber.
