Abstract
A technique of improving an adhesion between a metal precipitated in a recess of a substrate and a surface partitioning the recess in an electroless plating processing in which a plated metal is deposited from the bottom of the recess is provided. A substrate liquid processing method includes preparing a substrate including a recess and a wiring exposed at a bottom of the recess; forming a self-assembled monolayer on a side wall of the recess; attaching an intermolecular binder, which is allowed to be bonded to both a metal and the self-assembled monolayer, to the self-assembled monolayer; and burying, by supplying an electroless plating solution to the recess in a state where the intermolecular binder is attached to the self-assembled monolayer to precipitate the metal in the recess, the metal in the recess while bringing the metal into close contact with the intermolecular binder.
