Abstract

Two or more coatings applied to processing elements of a plasma processing system are treated with protective barriers or coatings. A method is described for adjoining two or more coatings on the processing element. Having applied a first protective barrier, a portion of the first protective barrier is treated. A second protective barrier is then applied over at least a portion of a region to which the first protective barrier was applied.
