    摘要: A system and method for magnetically filtering an ion beam during an ion implantation into a workpiece is provided, wherein ions are emitted from an ion source and accelerated the ions away from the ion source to form an ion beam. The ion beam is mass analyzed by a mass analyzer, wherein ions are selected. The ion beam is then decelerated via a decelerator once the ion beam is mass-analyzed, and the ion beam is further magnetically filtered the ion beam downstream of the deceleration. The magnetic filtering is provided by a quadrapole magnetic energy filter, wherein a magnetic field is formed for intercepting the ions in the ion beam exiting the decelerator to selectively filter undesirable ions and fast neutrals.

    摘要: This invention relates to a method of measuring a property of an ion beam, for example an ion beam current profile or the emittance of an ion beam. A Faraday array comprising an array of ion beam current sensors is employed. The array can provide an ion beam current profile at the plane of the array. The Faraday array is also used in conjunction with an occluding element that may be moved through the ion beam upstream of the Faraday array, there obscuring varying portions of the ion beam from the Faraday array. Suitable manipulation of the signals from the Faraday allows the ion beam current profile to be determined for the plane of the occluding element, and also for the emittance of the ion beam at the plane of the occluding element to be determined.
