    Abstract: The inventive concept relates to an apparatus for treating a substrate. According to an embodiment, the substrate treating apparatus includes a housing having a process space therein, a support unit that supports the substrate in the housing, a nozzle that dispenses a treatment liquid onto the substrate supported on the support unit, and a liquid supply unit that supplies the treatment liquid to the nozzle, in which the liquid supply unit includes a container having a storage space in which the treatment liquid is stored, a liquid supply tube that causes the treatment liquid to flow from the container to the nozzle, and a microwave applying member that applies microwaves to the treatment liquid before the treatment liquid is supplied to the nozzle.

    Abstract: An apparatus and a method for performing liquid treatment for a substrate are provided. The apparatus for treating the substrate includes a treating container having a treatment space inside the treating container, a substrate support unit to support a substrate in the treatment space, and a liquid supply unit to supply treatment liquid to the substrate supported by the substrate support unit. The liquid supply unit includes a nozzle, a supply line to supply the treatment liquid to the nozzle and having a first valve mounted in the supply line, and a discharge line branching from a branch point which is a point downstream of the first valve in the supply line to discharge the treatment liquid from the supply line, and having a second valve mounted in the discharge line. A valve is absent in an area between the branch point and the nozzle, in the supply line.

    Abstract: A method for treating a substrate is provided. The method includes supplying a first treating liquid to a treating target surface of the substrate while the substrate is rotating, and subsequently, supplying a second treating liquid having a surface tension lower than a surface tension of the first treating liquid to the substrate while an evaporation inhibiting agent in a vapor state is present around the first treating liquid supplied to the substrate, such that the first treating liquid on the substrate is substituted with the second treating liquid. Thus, a vapor atmosphere may be formed around a cleaning liquid applied to the substrate. Thus, a liquid-film destroying phenomenon may be prevented in a procedure in which the cleaning liquid is replaced with an organic solvent.
