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; and a cantilever configured to couple the support plate with the first electrode; an adjustment screw having a second thread, the second thread engaging the first thread for pitch adjustment, wherein turning the adjustment screw causes a first translation of a portion of the support plate relative to the adjustment screw, the first translation of the portion of the support plate configured to cause a first rotation of the support plate inward or outward 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 orthogonal to the insertion direction.
