摘要
Embodiments of the present invention generally provide a process kit for use in a physical vapor deposition (PVD) chamber. In one embodiment, the process kit provides a controlled gas flow between the cover ring and the shield that contributes to an adjustable process spacing, centering between the cover ring and the shield, and uniform gas distribution, Such a process kit facilitates greater process uniformity and repeatability with longer chamber component service life.
