  • Publication number: 20240038533
    Abstract: The present disclosure provides a substrate processing method and a substrate processing apparatus which are effective in preventing pattern collapse of an uneven pattern. The substrate processing method according to an exemplary embodiment includes replacing a liquid in a recess of a substrate having an uneven pattern of a negative type resist including a metal formed on a surface of the substrate with a solid-state stiffener, and subjecting the substrate to a molecular weight reduction processing that reduces the number of intermolecular bonds contained in the solid-state stiffener while maintaining the solid-state stiffener in a solid state.

  • Patent number: 11848189
    Abstract: A substrate processing method includes supplying a developing liquid configured to form a resist pattern onto a surface of a substrate on which a resist film is formed; performing multiple cycles of a cleaning processing of supplying a modifying liquid containing a modifying agent having a hydrophilic group onto the surface of the substrate on which the resist pattern is formed and supplying a rinse liquid configured to remove the modifying liquid onto the surface of the substrate; and drying the surface of the substrate after performing the multiple cycles of the cleaning processing.
