  • Publication number: 20140332498
    Abstract: Provided are a substrate holder, a substrate supporting apparatus, a substrate processing apparatus, and a substrate processing method. Particularly, there are provided a substrate holder, a substrate supporting apparatus, a substrate processing apparatus, and a substrate processing method that are adapted to improve process efficiency and etch uniformity at the back surface of a substrate.
    Type: Application

  • Patent number: 8373086
    Abstract: Provided are a plasma processing apparatus and method. The plasma processing apparatus includes a chamber, an upper electrode, a lower electrode, a substrate support, and a movement member. The upper electrode is disposed at an inner upper portion of the chamber. The lower electrode faces the upper electrode at an inner lower portion of the chamber to support a substrate such that a bevel of the substrate is exposed in a substrate level etching process. The substrate support is disposed between the upper electrode and the lower electrode to support the substrate such that a central region of a bottom surface of the substrate is exposed in a substrate backside etching process. The movement member is configured to move the substrate support to separate the substrate from the substrate support in the substrate backside etching process.
