Abstract:
1. A high temperature electrode connection assembly for a wafer-processing pedestal comprising: an electrode rod having a plate adapter portion and a cup for mounting to a stud embedded in a pedestal; a floating plate having an outer surface and an aperture for receiving the electrode rod, the floating plate configured to contact an inner surface of the pedestal to resist lateral movement of the electrode rod; an anti-rotation retainer ring configured to frictionally engage the electrode rod; and an anti-rotation post extending from the outer surface of the floating plate, the anti-rotation post configured to limit rotation of the anti-rotational retainer ring such that the anti-rotation post and anti-rotational retainer ring are together configured to limit rotation of the electrode rod with respect to the floating plate.
