Abstract:
1. A method of treating a bipolar electrostatic chuck having a front surface and a back surface and comprising a first electrode disposed at the front surface, a second electrode at the front surface and an anodized layer disposed on the front surface, the first electrode and the second electrode, said method comprising: measuring a first parameter of the electrostatic chuck; discarding the electrostatic chuck if the first measured parameter is not within a first predetermined range; cleaning the electrostatic chuck if the first measured parameter is within the first predetermined range; sealing gaps between the first electrode and the second electrode at the front surface with a sealant, without displacing the first electrode relative to the second electrode; eliminating the anodized layer; and disposing a new anodized layer onto the front surface, the first electrode and the second electrode.
