  • Patent number: 9529267
    Abstract: A method for processing a substrate includes arranging the substrate on which a photoresist layer is formed and providing a treatment liquid for removing the photoresist layer on the substrate. The method also includes providing a mist including deionized water or hydrogen peroxide on the substrate to make contact with the treatment liquid so as to increase a temperature of the treatment liquid. Therefore, efficiency of removing the photoresist layer may be improved.
    Type: Grant

  • Publication number: 20130284212
    Abstract: An apparatus for processing substrate includes a spin chuck, a first nozzle and a second nozzle. The spin chuck fixes and spins the substrate on which a photoresist layer is formed. The first nozzle is disposed over the spin chuck and provides a treatment liquid on the substrate so as to remove the photoresist layer. The second nozzle is disposed over the spin chuck and provides a mist including deionized water or hydrogen peroxide on the substrate to make contact with the treatment liquid so as to increase a temperature of the treatment liquid. Therefore, efficiency of removing the photoresist layer may be improved.

  • Patent number: 8540854
    Abstract: Provided are a substrate plating apparatus and a substrate plating method. In the substrate plating apparatus, a substrate support member supports a substrate to allow a plating surface to look up. A plating solution containing positive ions dissolved from a positive electrode is supplied from a plating solution supply member onto the substrate at an upper side of the substrate support member. A plating bath surrounds the substrate support member. The substrate support member is rotated in a state where it is immersed into the plating solution and an additive. The substrate can be supported by the substrate support member without reversing the substrate. Also, a pattern defect due to bubbles generated during a plating process can be prevented.
