Abstract
Method for operating a processing system and refurbishing a ceramic substrate holder within a process chamber of the processing system are described. The method includes plasma processing one or more substrates on the ceramic substrate holder, where the processing causes erosion of a nitride material of the ceramic substrate holder. The method further includes refurbishing the ceramic substrate holder in-situ without a substrate residing on the ceramic substrate holder, where the refurbishing includes exposing the ceramic substrate holder to a plasma-excited nitrogen-containing gas in the process chamber to at least partially reverse the erosion of the nitride material.
