Abstract: The inventive concept provides an apparatus for treating a substrate by using a supercritical fluid. In an embodiment, the apparatus may include a process chamber that provides a treatment space, and including a chamber heater that increases a temperature of an interior of the treatment space, a substrate support provided in the treatment space and that supports the substrate, and a substrate heating member that heats a lower surface of the substrate while contacting the lower surface of the substrate.
