摘要： A parallelizing component (439) of an ion implantation system (410) comprises two angled dipole magnets (439a, 439b) that mirror one another and serve to bend an ion beam (424) traversing therethrough to have a substantially "s" shape. This s bend serves to filter out contaminants of the beam, while the dipoles also parallelize the beam to facilitate uniform implant properties across the wafer (430), such as implant angle, for example. Additionally, a " deceleration stage (457) is included toward the end of the implantation system so that the energy of the beam can be kept relatively high throughout the beamlihe to mitigate beam blowup.

摘要： One or more aspects of the present invention pertain to a measurement component that facilitates determining a relative orientation between an ion beam and a workpiece. The measurement component is sensitive to ion radiation and allows a relative orientation between the measurement component and the ion beam to be accurately determined by moving the measurement component relative to the ion beam. The measurement component is oriented at a known relationship relative to the workpiece so that a relative orientation between the workpiece and beam can be established. Knowing the relative orientation between the ion beam and workpiece allows the workpiece to be oriented to a specific angle relative to the measured beam angle for more accurate and precise doping of the workpiece, which enhances semiconductor fabrication.

摘要： Some aspects of the present invention facilitate ion implantation by using a magnetic beam scanner (106, 300) that includes first and second magnetic elements having a beam path region therebetween. One or more magnetic flux compression elements (140a, b, 302, 304) 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.

摘要： A steering element is included in an ion implantation system to direct or "steer" an ion beam (624) to a scan vertex (651) of a scanning element (636) downstream of the steering element. In this manner, the scan vertex of the scanning element coincides with the focal point of a parallelizing element (630) downstream of the scanning element. This allows the beam to emerge from the parallelizing element at an expected angle so that ions can be implanted in a desired manner into a workpiece located downstream of the parallelizing element.

摘要： A plasma generator for space charge neutralization of an ion beam is disclosed and resides within an ion implantation system operable to generate an ion beam and direct the ion beam along a beamline path. The plasma generator comprises an electric field generation system operable to generate an electric field in a portion of the beamline path, and a magnetic field generation system operable to generate a magnetic field in the portion of the beamline path, wherein the magnetic field is perpendicular to the electric field. The plasma generator further comprises a gas source operable to introduce a gas in a region occupied by the electric field and the magnetic field. Electrons in the region move in the region due to the electric field and the magnetic field, respectively, and at least some of the electrons collide with the gas in the region to ionize a portion of the gas, thereby generating a plasma in the region.

摘要： A system (200) and method for magnetically filtering an ion beam (210) during an ion implantation into a workpiece (228) is provided, wherein ions are emitted from an ion source (212) and accelerated the ions away from the ion source to form an ion beam. The ion beam is mass analyzed by a mass analyzer (214), wherein ions are selected. The ion beam is then decelerated via a decelerator (242) once the ion beam is mass-analyzed, and the ion beam is further magnetically filtered downstream of the deceleration. The magnetic filtering is provided by a quadrapole (quadrupole) magnetic energy filter (250), 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 (264).
