The present invention generally comprises a backing plate reinforcement apparatus for use in a plasma enhanced chemical vapor deposition apparatus. When processing large area substrates, the backing plate extending across the chamber may also be quite large. By supporting a central area of the backing plate with a frame structure, the backing plate may be maintained substantially planar. Alternatively, as necessary, the contour of the backing plate may be adjusted to suit the particular needs of the process.
