    Abstract: A system, method, and apparatus for mitigating contamination associated with ion implantation are provided. An ion source, end station, and mass analyzer positioned between the ion source and the end station are provided, wherein an ion beam is formed from the ion source and selectively travels through the mass analyzer to the end station, based on a position of a beam stop assembly. The beam stop assembly selectively prevents the ion beam from entering and/or exiting the mass analyzer, therein minimizing contamination associated with an unstable ion source during transition periods such as a start-up of the ion implantation system.

    Abstract: An exemplary ion source for creating a stream of ions has a chamber body that at least partially bounds an ionization region of the arc chamber. The arc chamber body is used with a hot filament arc chamber housing that either directly or indirectly heats a cathode to sufficient temperature to cause electrons to stream through the ionization region of the arc chamber. A seals has a ceramic body having an outer wall that abuts the arc chamber body along a circumferential outer lip. The seal also has one or more radially inner channels bounded by one or more inner walls spaced inwardly from the outer wall.

    Abstract: The present invention is directed to a beam control circuit and method used to minimize particle contamination in an ion implantation system by reducing the duty factor of the ion beam. In one embodiment the beam control circuit comprises a high voltage switch connected in series with a power supply and an ion source portion of the ion implantation system, wherein the switch is operable to interrupt or reestablish a connection between the power supply and an electrode of the ion source including electrodes for plasma production. The beam control circuit also comprises a switch controller operable to control the duty factor of the ion beam by controlling the switch to close before a start of ion implantation and to open after a completion of implantation or at other times when the beam is not needed, thereby minimizing beam duty and particle contamination. The beam control technique may be applied to wafer doping implantation and duty factor reduction. Protection circuits for the high voltage switch absorb energy from reactive components and clamp any overvoltages.

    Abstract: A magnetic deflector for an ion beam is disclosed and comprises first and second coils. The coils are positioned above and below the beam, respectively, and extend along a width of the beam. Current passes through the coils to generate a magnetic field therebetween that is generally perpendicular to a direction of travel of the beam along substantially the entire width thereof. In another aspect of the invention, a method of deflecting a beam prior to implantation into a workpiece is disclosed. The method includes determining one or more properties associated with the beam and selectively activating one of a magnetic deflection module and an electrostatic deflection module based on the determination.
