  • Publication number: 20230005768
    Abstract: Embodiments of the inventive concept described herein relate to an apparatus and method for removing an adhesive exposed to the outside from an object being processed. The apparatus for removing the adhesive exposed to the outside from an edge region of the object being processed, in which the object has a patterned substrate and a support plate bonded together by the adhesive, The cover liquid nozzle dispenses the cover liquid onto a cover area of a top surface of the object other than the exposed area, and the controller controls the cover liquid dispensing member to adjust a flow rate of the cover liquid to cause a removal rate of the adhesive to remain constant.

  • Publication number: 20210066099
    Abstract: A method for processing a substrate includes a liquid treatment step of performing liquid treatment on the substrate by dispensing a treatment liquid onto the rotating substrate and a cleaning step of stopping the dispensing of the treatment liquid and dispensing a cleaning solution onto the substrate. In the cleaning step, a first liquid is dispensed from a first nozzle above the rotating substrate to a point spaced apart from the center of the substrate in a first direction, and a second liquid is dispensed from a second nozzle above the rotating substrate to a point spaced apart from the center of the substrate in a second direction. When viewed from above, the first liquid flows toward the second nozzle after dispensed onto the substrate, and the second liquid flows toward the first nozzle after dispensed onto the substrate.

  • Patent number: 10211075
    Abstract: An apparatus and a method for treating a substrate with liquid are disclosed. The substrate treating apparatus comprises a substrate supporting unit for supporting the substrate, a liquid supply unit for supplying a liquid to the substrate supported on the substrate supporting unit, and a controller for controlling the liquid supply unit, wherein the liquid supply unit comprises a first nozzle for supplying a first liquid and a second nozzle for supplying a second liquid, and a second area where the second liquid is supplied on the substrate is provided within a first area where the first liquid is supplied on the substrate. The first liquid and the second liquid supplied with a hydrophobic film are discharged with different ways from each other. Thereby, particles with various sizes may be removed depending on each discharge methods.
