    Abstract: An extraction assembly may include an extraction plate for placement along a side of a plasma chamber, and having an extraction aperture, elongated along a first direction, and having an aperture height, extending along a second direction, perpendicular to the first direction. The extraction plate defines an inner surface along the extraction aperture, lying in a first plane. A beam blocker is disposed over the extraction aperture, and has an outer surface, disposed in a second plane, different than the first plane. As such, the beam blocker overlaps with the extraction plate along a first edge of the extraction aperture by a first overlap distance, and overlaps with the extraction plate along a second edge of the extraction aperture by a second overlap distance, so as to define a first extraction slit, along the first edge, and a second extraction slit along the second edge.

    Abstract: An extraction plate for an ion beam system. The extraction plate may include an insulator body that includes a peripheral portion, to connect to a first side of a plasma chamber, and further includes a central portion, defining a concave shape. As such, an extraction aperture may be arranged along a first surface of the central portion, where the first surface is oriented at a high angle with respect to the first side. The extraction plate may further include a patterned electrode, comprising a first portion and a second portion, affixed to an outer side of the insulator body, facing away from the plasma chamber, wherein the first portion is separated from the second portion by an insulating gap.
