    Abstract: Embodiments of the disclosure include an apparatus and a method for controlling plasma uniformity by controlling plasma density in the bulk plasma over the center region and circumferential edge region of the substrate. Plasma uniformity can be controlled by use of an RF tuning circuit coupled to one of a plurality of electrodes positioned relative to a substrate during plasma processing. By adjusting the electrical characteristics of at least one of the RF tuning circuits, the effect that the generated RF fundamental frequency and related RF harmonic frequencies have on the plasma processing results can be controlled. Beneficially, the use of one or more of the tuning circuits and methods of using the same may be used to provide individual tuning knobs for controlling reactive neutral species concentration, ion energy and angular distribution, ion directionality and directionality uniformity, and separately controlling ion flux and reactive neutral species uniformity across the surface of the substrate.

    Abstract: An edge ring centering system for a plasma processing system includes a processing chamber including a substrate support and R edge ring lift pins, where R is an integer greater than or equal to 3. An edge ring includes P grooves located on a bottom surface thereof, where P is an integer greater than or equal to R. A robot arm includes an end effector. A controller is configured to cause the optical sensor to sense a first position of the edge ring on the end effector; cause the robot arm to deliver the edge ring to a first center location on the edge ring lift pins; retrieve the edge ring from the edge ring lift pins; and cause the optical sensor to sense a second position of the edge ring on the end effector.

    Abstract: When preparing a Hole-Free Phase Plates (HFPP) a preferably featureless thin film should be placed with high accuracy in the diffraction plane of the TEM, or a plane conjugate to it. Two methods for accurately placing the thin film in said plane are described. One method uses a Ronchigram of the thin film while the TEM is in imaging mode, and the magnification of the Ronchigram is tuned so that the magnification in the middle of the Ronchigram is infinite. The second method uses electrons scattered by the thin film while the TEM is in diffraction mode. When the thin film does not coincide with the diffraction plane, electrons scattered by the thin film seem to originate from another location than the cross-over of the zero beam. This is observed as a halo. The absence of the halo is proof that the thin film coincides with the diffraction plane.

    Abstract: In an exemplary process for lower dose rate ion implantation of a work piece, an ion beam may be generated using an ion source and an extraction manipulator. The extraction manipulator may be positioned at a gap distance from an exit aperture of the ion source. A current of the ion beam exiting the extraction manipulator may be maximized when the extraction manipulator is positioned at an optimal gap distance from the exit aperture. The gap distance at which the extraction manipulator is positioned from the exit aperture may differ from the optimal gap distance by at least 10 percent. A first potential may be applied to a first set of electrodes. An x-dimension of the ion beam may increase as the ion beam passes through the first set of electrodes. The work piece may be positioned in the ion beam to implant ions into the work piece.
