  • Patent number: 8138484
    Abstract: Some aspects of the present invention facilitate ion implantation by using a magnetic beam scanner that includes first and second magnetic elements having a beam path region therebetween. One or more magnetic flux compression elements are disposed proximate to the beam path region and between the first and second magnetic elements. During operation, the first and magnetic elements cooperatively generate an oscillatory time-varying magnetic field in the beam path region to scan an ion beam back and forth in time. The one or more magnetic flux compression elements compress the magnetic flux provided by the first and second magnetic elements, thereby reducing the amount of power required to magnetically scan the beam back and forth (relative to previous implementations). Other scanners, systems, and methods are also disclosed.

  • Patent number: 8124947
    Abstract: A system and method are provided for implanting ions into a workpiece in a plurality of operating ranges. A desired dosage of ions is provided, and a spot ion beam is formed from an ion source and mass analyzed by a mass analyzer. Ions are implanted into the workpiece in one of a first mode and a second mode based on the desired dosage of ions, where in the first mode, the ion beam is scanned by a beam scanning system positioned downstream of the mass analyzer and parallelized by a parallelizer positioned downstream of the beam scanning system. In the first mode, the workpiece is scanned through the scanned ion beam in at least one dimension by a workpiece scanning system. In the second mode, the ion beam is passed through the beam scanning system and parallelizer un-scanned, and the workpiece is two-dimensionally scanned through the spot ion beam.

  • Patent number: 8124946
    Abstract: 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.
