Abstract
A method for reducing energy consumption, and amounts of cleaning liquids and rinse liquids used. A cleaning head has a plurality of cleaning units and a drying unit. The organic, and inorganic, substance cleaning portions of each cleaning head, blows a first, and a second, cleaning agent selectively over a portion to be cleaned of a substrate, and sucks reaction products etc. through a first, and second, suction mouth, respectively. A rinse portion blows pure water over the portion of the substrate from which inorganic substances have been removed, and sucks its vapor through a third suction mouth. The drying unit dries the substrate by blowing out a heated gas from a hot wind blowing-out mouth. A light guide illuminates the portion to be cleaned, of the substrate, with ultraviolet light, and thereby decomposes residual organic substances.
