Abstract:
1. A substrate treatment method of performing at least photolithography processing and etching treatment for a substrate in this order a plurality of times, comprising the steps of: forming a resist film on a front surface of the substrate and performing exposure processing on the resist film on the front surface; inverting the substrate to direct a rear surface of the substrate upward and forming a coating film on the rear surface of the substrate after the exposure processing in the photolithography processing is performed on the resist film on the front surface of the substrate; inverting the substrate to direct the front surface of the substrate upward and performing the etching treatment on the resist film on the front surface of the substrate; and inverting the substrate to direct a rear surface of the substrate upward and removing the coating film from the rear surface of the substrate between the forming the coating film and performance of next exposure processing.
