  • Publication number: 20240418443
    Abstract: The present invention relates to a substrate treating method and a substrate treating apparatus. The substrate treating method is for treating the substrate. The substrate has a pattern formed on a surface of the substrate. The substrate treating method includes the hydrophilization step, the first supplying step, the solidified film forming step, and the sublimation step. In the hydrophilization step, the hydroxy group is formed on the surface of the substrate. In the first supplying step, the drying auxiliary liquid is supplied to the substrate having the hydroxy group. The drying auxiliary liquid contains the sublimable substance and the first solvent. The sublimable substance contains an organic compound containing an oxime group. In the solidified film forming step, the first solvent evaporates from the drying auxiliary liquid on the substrate. In the solidified film forming step, the solidified film is formed on the substrate. The solidified film contains the sublimable substance.

  • Patent number: 10755951
    Abstract: In a substrate processing apparatus, an outer edge portion of a substrate in a horizontal state is supported from below by an annular substrate supporting part, and a lower surface facing part having a facing surface facing a lower surface of the substrate is provided inside the substrate supporting part. A gas ejection nozzle for ejecting heated gas toward the lower surface is provided in the lower surface facing part, and the substrate is heated by the heated gas when an upper surface of the rotating substrate is processed with a processing liquid ejected from an upper nozzle. Further, a lower nozzle is provided in the lower surface facing part, to thereby perform a processing on the lower surface with a processing liquid. Since the gas ejection nozzle protrudes from the facing surface, a flow of the processing liquid into the gas ejection nozzle can be suppressed during the processing.
