Abstract: A technique for uniformity tuning in an ion implanter system is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for ion beam uniformity tuning. The method may comprise generating an ion beam in an ion implanter system. The method may also comprise tuning one or more beam-line elements in the ion implanter system to reduce changes in a beam spot of the ion beam when the ion beam is scanned along a beam path. The method may further comprise adjusting a velocity profile for scanning the ion beam along the beam path such that the ion beam produces a substantially uniform ion beam profile along the beam path.

Abstract: A technique for high-efficiency ion implantation is disclosed. In one particular exemplary embodiment, the technique may be realized as an apparatus for high-efficiency ion implantation. The apparatus may comprise one or more measurement devices to determine a shape of an ion beam spot in a first dimension and a second dimension. The apparatus may also comprise a control module to control movement of the ion beam across a substrate according to a two-dimensional velocity profile, wherein the two-dimensional velocity profile is determined based at least in part on the shape of the ion beam spot, and wherein the two-dimensional velocity profile is tunable to maintain a uniform ion dose and to keep the ion beam spot from going fully off the substrate surface.
