Abstract:
1. A mechanism for adjusting an orientation of a first electrode in a plasma processing system, the plasma processing system configured for processing at least a substrate, the plasma processing system further including at least a plasma processing chamber, the plasma processing chamber including at least a chamber wall, the first electrode positioned inside the plasma processing chamber, the substrate configured to be inserted into the plasma processing chamber in an insertion direction, the mechanism comprising: a support plate coupled with the first electrode, the support plate having a first thread, the support plate disposed outside the chamber wall and pivoted relative to the chamber wall; a cam coupled with the support plate, the cam configured to cause a first translation of a portion of the support plate relative to the chamber wall, thereby causing a first rotation of the support plate relative to the chamber wall, the first rotation of the support plate configured to cause a first rotation of the first electrode with respect to a first axis that is parallel to the insertion direction; a bar coupled with the cam and coupled with the support plate, the bar configured to be actuated by the cam; and a lift plate disposed between the chamber wall and the support plate, the lift plate including at least a slot coupled with the bar, the slot configured to guide and limit movement of the bar, thereby limiting the first rotation of the first electrode.
