Abstract:
A device for cleaning a bevel edge of a semiconductor substrate. The device includes: a lower support having a cylindrical top portion; a lower plasma-exclusion-zone (PEZ) ring surrounding the outer edge of the top portion and adapted to support the substrate; an upper dielectric component opposing the lower support and having a cylindrical bottom portion; an upper PEZ ring surrounding the outer edge of the bottom portion and opposing the lower PEZ ring; and at least one radiofrequency (RF) power source operative to energize process gas into plasma in an annular space defined by the upper and lower PEZ rings, wherein the annular space encloses the bevel edge.
