    Abstract: An ion implantation system for providing a mass analyzed ribbon beam that comprises an ion beam source that includes a plasma source and an extraction component, wherein the extraction component is configured to extract a diverging ion beam and direct the ion beam to a window frame magnet assembly. The window frame magnet assembly comprises two pairs of coils orthogonally arranged within a window shaped yoke to produce an independently controllable uniform cross-field magnetic field. The first set of coils create an uniform field across the width of the diverging beam to convert it to a uniform parallel broad ion beam. The second set of coils bend the sheet of the ion beam in orthogonal direction to give mass dispersion for ion mass selection.

    Abstract: A glitch duration threshold is determined based on an allowable dose uniformity, a number of passes of a workpiece through an ion beam, a translation velocity, and a beam size. A beam dropout checking routine repeatedly measures beam current during implantation. A beam dropout counter is reset each time beam current is sufficient. On a first observation of beam dropout, a counter is incremented and a position of the workpiece is recorded. On each succeeding measurement, the counter is incremented if beam dropout continues, or reset if beam is sufficient. Thus, the counter indicates a length of each dropout in a unit associated with the measurement interval. The implant routine stops only when the counter exceeds the glitch duration threshold and a repair routine is performed, comprising recalculating the glitch duration threshold based on one fewer translations of the workpiece through the beam, and performing the implant routine starting at the stored position.

    Abstract: Methods and a system of an ion implantation system are disclosed that are capable of increasing beam current above a maximum kinetic energy of a first charge state from an ion source without changing the charge state at the ion source. Positive ions having a first positive charge state are selected into an accelerator. The positive ions of the first positive charge state are accelerated in acceleration stages and stripped to convert them to positive ions of a second charge state. A second kinetic energy level higher than the maximum kinetic energy level of the first charge state can be obtained.
