  • Publication number: 20250125121
    Abstract: A two-electrode continuous plasma processing system includes a processing chamber having a clamping device, a moving device, a first and a second electrodes, and a first and a second radio frequency power sources. When an object moves into a processing space of the processing chamber, the moving device controls the second electrode to drive the object to move toward the first electrode, and actuates the second electrode and the clamping device to clamp and fix the object. The first radio frequency power source provides the first electrode with a first radio frequency energy to control the density of plasma. The second radio frequency power source provides the second electrode with a second radio frequency energy to control the ion energy of the plasma. Therefore, the plasma is efficiently stabilized, lowering the probability of object damage.

  • Publication number: 20250125127
    Abstract: A continuous plasma processing system with adjustable electrode includes a frame shape carrier plate for holding a to-be-processed object, a loading chamber for inputting the to-be-processed object, a processing chamber, and an unloading chamber for outputting the finished object. The processing chamber has a first electrode, a second electrode, and a moving device controlling the second electrode to move between an electrically disconnected position and an electrically conducted position. When the second electrode is away from the first electrode and does not contact the to-be-processed object, the second electrode is at the electrically disconnected position. When the second electrode moves toward the first electrode to push the to-be-processed object to leave the frame shape carrier plate, the second electrode is at the electrically conducted position. The plasma electric field is prevented from being affected by particles on the carrier plate.
