发明名称 Apparatus for washing both surfaces of a substrate
摘要 A method for washing both surfaces of a substrate, comprising (a) a first washing step for washing a front surface of a substrate, which is kept rotated, by bringing a scrubbing member into contact with said front surface of the substrate while supplying a washing liquid onto the front surface, (b) a second washing step for washing a back surface of the substrate, which is kept rotated, by bringing a scrubbing member into contact with said back surface of the substrate while supplying a washing liquid onto the back surface, (c) a heating step for drying under heat the wet surfaces of the substrate, (d) a recipe determining step for determining whether said heating step (c) is performed, at a period between said first washing step (a) and second washing step (b) and at a period after the second washing step (b), whether the heating step (c) is performed only once after the second washing step (b), or whether the heating step (c) is not performed, and (e) a conducting step for performing or not performing the heating step (C) in accordance with the recipe determined in said recipe determining step (d).
