    Abstract: A high energy beam verification, calibration, and profiling system includes a conductive base plate, supports extending from the base plate, a plurality of conductors, a data logger electrically connected to the conductors, and a computer electrically connected to the data logger. Each conductor is supported by some of the supports such that each conductor is insulated from the conductive base plate. Each conductor has a profile intersecting with profiles of at least some of the other conductors to define a multidirectional and two-dimensional array of conductors. The data logger receives and records data associated with electrical charges flowing through the conductors. The computer is adapted to receive, manipulate, and display the data recorded by the data logger for comparison of beam characteristics at different locations across a high energy beam build area.

    Abstract: A system and method of improving the performance and extending the lifetime of an ion source is disclosed. The ion source includes an ion source chamber, a suppression electrode and a ground electrode. In the processing mode, the ion source chamber may be biased to a first positive voltage, while the suppression electrode is biased to a negative voltage to attract positive ions from within the chamber through an aperture and toward the workpiece. In the cleaning mode, the ion source chamber may be grounded, while the suppression electrode is biased using a power supply having a high current capability. The voltage applied to the suppression electrode creates a plasma between the suppression electrode and the ion source chamber, and between the suppression electrode and the ground electrode.

    Abstract: A plasma processing apparatus capable of optimizing a plasma process is provided. The plasma processing apparatus includes a control unit for controlling a minimum energy and a maximum energy of ions incident onto a substrate independently of each other such that ion energy of the ions are concentrated at a first energy band and a second energy band respectively. In the plasma processing apparatus, the oxide film is etched to form a hole within the oxide film, the first energy band is lower than a first energy value at which the oxide film is etched while the organic film is not etched, and the second energy band is higher than a second energy value at which an etching yield at an inclined surface of the hole is higher than an etching yield of an upper surface of the organic film.

    Abstract: A composite charged particle beam apparatus includes a FIB column for irradiating a thin sample with a FIB and a GIB column for irradiating the thin sample with a GIB. The thin sample is placed on a sample stage, and a tilt unit tilts the thin sample about a tilt axis of the sample stage, the tilt axis being orthogonal to the FIB irradiation axis and being located inside a plane formed by the FIB irradiation axis and the GIB irradiation axis. A tilt sample holder is mounted on the sample stage and fixes the thin sample such that a cross-sectional surface of the thin sample is tilted at a constant angle with respect to the GIB irradiation axis and the azimuth angle of the GIB column can be changed by rotation of the sample stage.
