Abstract: In the coating treatment apparatus, in a first treatment chamber, the front and rear surfaces of the substrate held by a transfer arm are inverted by a turning mechanism, and a coating solution is applied from a coating nozzle to the rear surface of the substrate. The substrate is transferred into a second treatment chamber, in which the coating solution on the rear surface is heated by a heating unit to cure, thereby forming a coating film on the rear surface of the substrate. The formation of the coating film by the coating treatment apparatus is performed before exposure processing, whereby the rear surface of the substrate can be flat for the exposure processing.

Abstract: According to the present invention, during the photolithography processing of a substrate, exposure processing is performed immediately after removal of a coating film on the rear surface of the substrate, and a coating film is formed on the rear surface of the substrate immediately after the exposure processing. Thereafter, etching treatment and so on are performed, and a series of these treatment and processing steps are performed a predetermined number of times. The coating film has been formed on the rear surface of the substrate at the time for the etching treatment, so that even if the coating film gets minute scratches, the rear surface of the substrate itself is protected by the coating film and thus never scratched. Further, since the coating film on the rear surface of the substrate is removed immediately before the exposure processing, the rear surface of the substrate can be flat for the exposure processing.
