    Abstract: Provided is an ion implanter or the like capable of shortening a replacement time of workpieces. An ion implantation method includes (a) deflecting an ion beam by at least one of an electric field and a magnetic field in an irradiation-disabled direction in which a wafer is incapable of being irradiated with the ion beam after a first wafer is irradiated with the ion beam directed in an irradiation-enabled direction in which the wafer is capable of being irradiated with the ion beam; (b) moving the first wafer from an ion implantation position, subsequently to the step (a); (e) disposing a second wafer different from the first wafer at the ion implantation position, subsequently to the step (b); and (f) returning the ion beam from the irradiation-disabled direction to the irradiation-enabled direction, subsequently to the step (e).

    Abstract: A method of attracting an object to a mounting table is provided. The object is a substrate, an edge ring, or a combination of the substrate and the edge ring. The mounting table is provided with an electrostatic chuck including electrodes. After the object is placed on the electrostatic chuck, n-phase alternating current (AC) voltages (n≥2) are applied to the electrodes. Each phase voltage of the n-phase AC voltages has a phase different from each other, and the phase voltage of the n-phase AC voltages is applied based on a self-bias voltage of the object.

    Abstract: A system and method for controlling electrostatic clamping of multiple platens on a spinning disk is disclosed. The system comprises a semiconductor processing system, such as a high energy implantation system. The semiconductor processing system produces a spot ion beam, which is directed to a plurality of workpieces, which are disposed on a spinning disk. The spinning disk comprises a rotating central hub with a plurality of platens. The plurality of platens may extend outward from the central hub and workpieces are electrostatically clamped to the platens. The central hub provides the electrostatic clamping voltages to each of the plurality of platens. Further, the plurality of platens may also be capable of rotation about an axis orthogonal to the rotation axis of the central hub. The central hub controls the rotation of each of the platens. Power connections and communications are provided to the central hub via the spindle assembly.
