  • Publication number: 20080233283
    Abstract: An apparatus and method for depositing a protective layer. The apparatus includes an anti-hydration module, wherein a substrate is loaded through a substrate input hole and mounted on a carrier; a load lock chamber, which is connected to the anti-hydration module and maintains a vacuum; a plurality of vacuum chambers; a depositing chamber, which is installed in one of the vacuum chambers; a target unit, which is installed in the depositing chamber and deposits a raw material of a protective layer on the substrate; a transferring unit which is continuously installed in the anti-hydration module, the load lock chamber, the vacuum chambers, and the depositing chamber, and transfers the substrate mounted on the carrier. Accordingly, since the carrier is not exposed to the atmosphere, moisture pressure inside the depositing chamber does not increase even if the apparatus is used for a long time.

  • Publication number: 20080202422
    Abstract: Provided is a plasma gun including: a cathode unit generating plasma; and a return electrode unit which ejects plasma generated in the cathode unit toward a target and returns electrons reflected from the target to a power source. The return electrode unit includes a frame, an insulating tube, and a gas flow unit. The frame includes a plasma outlet. The insulating tube electrically insulates the surface of the plasma outlet. The gas flow unit is formed to eject gases toward a target side end of the insulating tube.
