Abstract: The inventive concept provides a substrate treating method for etching a specific region on a substrate. The substrate treating method includes supplying a treating liquid to the substrate; and irradiating a laser to the specific region to locally heat the specific region; and wherein at the irradiating the laser, the laser is irradiated a plurality of times within the specific region, and the laser is irradiated to a region which does not overlap on the substrate, but which overlaps within the specific region.

Abstract: The inventive concept provides a substrate treating method. The substrate treating method includes pre-treating a substrate by cleaning the substrate; etching the substrate by supplying an etchant and heating a substrate supplied with the etchant; and post-treating the substrate after the etching the substrate, and wherein the pre-treating the substrate, the etching the substrate, and the post-treating the substrate are each performed in different chambers, a substrate on which the pre-treating the substrate is completed is transferred in a dry state to a chamber at which the etching the substrate is performed, and a substrate on which the etching the substrate is completed is transferred in a wetted state with a liquid to a chamber at which the post-treating the substrate is performed.

Abstract: Disclosed is a substrate treating apparatus. The substrate treating apparatus includes a body including an irradiation end, from which laser light is irradiated, a shaft coupled to the body, and a driver that supplies power to the shaft, the heating unit is swung about an axis of the shaft, and the controller moves the irradiation end of the heating unit to a target location on a substrate by adjusting a rotation angle of the heating unit and a rotation angle of the support unit.

Abstract: Disclosed is a method for treating a substrate, on which a plurality of reference marks and a pattern are formed. The method includes a process preparing operation, a location information acquiring operation of acquiring information on an actual location of the pattern, and a process executing operation of supplying a treatment liquid to the substrate, and heating the substrate by irradiating laser light to the pattern on the substrate, to which the treatment liquid is applied, the location information acquiring operation includes acquiring information on actual locations of, among the plurality of reference marks, at least three reference marks, and acquiring information of the actual location of the pattern through the information of the actual locations of the reference marks.

Abstract: Provided is an apparatus for treating a substrate, which includes: a support unit supporting a substrate; a liquid supply unit supplying a treatment liquid to the substrate supported on the support unit; a heating unit heating a specific location of the substrate by irradiating a laser to the specific location on the substrate supported on the support unit, and swingably moved between the specific location of the substrate, and a waiting location of deviating from the substrate; a coordinate unit disposed below an irradiation end portion to which the laser is irradiated from the heating unit when the heating unit is positioned at the waiting location; and an image module monitoring the laser irradiated from the heating unit, in which the image module calculates a movement distance in which the heating unit is swingably moved on the coordinate unit to measure a first length in a longitudinal direction of the heating unit.

Abstract: The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes a housing having a treating space; a support unit configured to support and rotate a substrate at the treating space; a liquid supply unit configured to supply a liquid to a substrate supported on the support unit; a post-treating unit configured to perform a post-treatment on the substrate supported on the support unit; and a monitoring unit configured to inspect a state of a liquid film formed of the liquid supplied onto the substrate.
