Abstract:
An apparatus for washing both surfaces of a substrate, comprising:a spin chuck for holding and rotating a substrate;a first washing section in which a scrubbing member is brought into contact with a front surface of a substrate, which is kept rotated, while supplying a washing liquid onto said front surface of the substrate for washing the front surface;a second washing section in which a scrubbing member is brought into contact with a back surface of the substrate, which is kept rotated, while supplying a washing liquid onto said back surface of the substrate for washing the back surface;a heating section for drying under heat the front and back surfaces of the substrate;a transfer arm mechanism for transferring the substrate into each of said first washing section, said second washing section, and said heating section;a recipe controller for controlling said first and second washing sections to permit the substrate to be washed in the second washing section after the substrate washing in the first washing section, and for determining whether the substrate should be dried in said heating section, between the washing in the first washing section and the washing in the second washing section and after the washing in the second washing section, respectively, whether the substrate should be dried only once after the washing in the second washing section, or whether the substrate should not be dried in the heating section; andcontrol means for controlling the heating in the heating section on the basis of the recipe determined in said recipe controller.
