  • Publication number: 20220415643
    Abstract: In a substrate processing method, a rinse process using a rinse solution is performed on a development-processed photoresist pattern on a substrate. A substitution process including a first substitution step using a mixed solution of a non-polar organic solvent and a surfactant and a second substitution step using the non-polar organic solvent is performed on the substrate. The substitution process is performed a plurality of times until the rinse solution remaining on the substrate is less than a predetermined value. A supercritical fluid drying process is performed on the substrate to dry the non-polar organic solvent remaining on the substrate.

  • Publication number: 20220290921
    Abstract: The inventive concept provides a method for treating a substrate. The method for treating a substrate comprises: a pressurization step for increasing a pressure of an inner space of a chamber by supplying a treating fluid to the inner space, after taking the substrate into the inner space; a flow step for generating a flow of the treating fluid by combination of supplying and discharging the treating fluid to and from the inner space; and a depressurization step of decreasing the pressure of the inner space by discharging the treating fluid from the inner space, and wherein the pressurization step comprises: a bottom side supply process for increasing the pressure of the inner space by supplying the treating fluid to a backside of the substrate taken into the inner space; and a top side supply process of increasing the pressure of the inner space by supplying the treating fluid to a top side of the substrate taken into the inner space.
