Claim 8:
9. A processing system, comprising:
a plasma chamber operable to generate a plasma; and
an extraction assembly, arranged along a side of the plasma chamber, the extraction assembly comprising:
an extraction plate including an extraction aperture, the extraction plate having a non-planar shape, and generating an extracted ion beam at a high angle of incidence with respect to a perpendicular to a plane of a substrate, when the plane of the substrate is arranged parallel to the side of the plasma chamber,
wherein the extraction plate comprises an interior extraction plate, the extraction assembly further comprising an exterior extraction plate, offset from the plasma chamber, wherein the extraction aperture comprises a first extraction aperture, disposed in the interior extraction plate, and wherein a second extraction aperture is disposed in the exterior extraction plate, and is aligned with the first extraction aperture.
