Method for joining a film onto a substrate

摘要

A method for joining a film onto a substrate comprises: a step (A) of floating the film on an interface between an aqueous liquid and a water-insoluble liquid; a step (B) of immersing the substrate into the aqueous liquid; a step (C) of stacking the substrate onto said one surface of the film in the aqueous liquid; a step (D) of immersing the stacked substrate and film into the water-insoluble liquid with maintaining the substrate being stacked on the film to adhere the film to the substrate; and a step (E) of drawing up the stacked substrate and film from the water-insoluble liquid with maintaining the substrate being stacked on the film to join the film onto the substrate.
