Patent ID: 7651585

Claim:
An apparatus for removing an edge polymer from a substrate, the apparatus comprising: a powered electrode; a first dielectric layer; a first wire mesh disposed between said powered electrode and said first dielectric layer, said first wire mesh surrounding said powered electrode, said first dielectric layer surrounding said first wire mesh; a second dielectric layer disposed between said first dielectric layer and said power electrode, wherein said first wire mesh is sandwiched between said first dielectric layer and said second dielectric layer; a grounded electrode disposed above an edge of said substrate, said powered electrode disposed between two portions of said grounded electrode, said grounded electrode including at least an orifice at one end of said grounded electrode for providing plasma to remove said edge polymer; and an inert gas jet positioned above a location on a surface said substrate, said location being away from said edge of said substrate, said inert gas jet configured to provide inert gas in a direction to push byproducts produced by said plasma away from said substrate in said direction.
