Abstract
A method of drying a substrate comprises: supplying a first air flowdownwardly in an inclined direction onto the substrate; supplying a second air flowupwardly in an inclined direction onto the substrate, while moving relatively the substrate and the upper and lower blowing portions so that the substrate, from the end area as a front of the substrate, passes between the upper blowing portion and the lower blowing portion; and controlling the first and second air flows such that a velocity component of the second air flow in an upward direction perpendicular to the virtual plane is smaller than a velocity component of the first air flow in a downward direction perpendicular to the virtual plane.
