Abstract: Methods and systems are provided for increasing the efficiency of the ion beam during scanning workpieces in ion implanting such that multiple wafers are arranged on a platen or support so that a greater portion of the beam scans the workpiece surface. Specifically, an apparatus is provided for ion implanting a plurality of workpieces. The apparatus includes an ion source for generating an ion beam having a scan width and a scan distance which defines a predetermined scan area, a holder for receiving the workpieces that are arranged so as to maximize the surface area of the workpieces present within the predetermined scan area. Thereby, a scanner may scan the ion beam over the predetermined scan area so that the utilization efficiency of said ion beam on the workpieces is increased.
