    摘要: A technique for providing a segmented electrostatic lens in an ion implanter is disclosed. In one particular exemplary embodiment, the technique may be realized as an electrostatic lens for use in an ion implanter. The lens may comprise an entrance electrode biased at a first voltage potential, wherein an ion beam enters the electrostatic lens through the entrance electrode. The lens may also comprise an exit electrode biased at a second voltage potential, wherein the ion beam exits the electrostatic lens through the exit electrode. The lens may further comprise a suppression electrode located between the entrance electrode and the exit electrode, the suppression electrode comprising a plurality of segments that are independently biased to manipulate an energy and a shape of the ion beam.

    摘要: A method and apparatus are disclosed for improving space charge neutralization adjacent a magnet of an ion implanter by confining the electrons inside a magnetic region thereof to reduce electron losses and therefore improve the transport efficiency of a low energy beam. A magnetic pole member for a magnet of an ion implanter is provided that includes an outer surface having a plurality of magnetic field concentration members that form magnetic field concentrations adjacent the magnetic pole member. Electrons that encounter this increased magnetic field are repelled back along the same magnetic field line rather than allowed to escape. An analyzer magnet and ion implanter including the magnet pole are also provided so that a method of improving low energy ion beam space charge neutralization in an ion implanter is realized.

    摘要: An ion implanter includes an ion source for generating an ion beam, a target site for supporting a target for ion implantation and a beamline defining a beam path between the ion source and the target site. In one aspect, a magnetic steerer is disposed between the ion source and the target site for at least partially correcting unwanted deviation of the ion beam from the beam path. The magnetic steerer may position the ion beam relative to an entrance aperture of an ion optical element. In another aspect, the beamline includes a deceleration stage for decelerating the ion beam from a first transport energy to a second transport energy. The deceleration stage includes two or more electrodes, wherein at least one of the electrodes is a grid electrode positioned in the beam path.
