    摘要: An ion beam source. The source includes multiple apertures bounded in close proximity by an extraction electrode for extracting positively charged ions from the source. Ions exiting the source combine downstream to form a broad beam which, in one utilization of the invention, is used for ion beam treatment of a silicon wafer. Individual electrodes in close proximity to the extraction electrode can be biased to either inhibit or allow backstreaming of neutralizing electrons from beam portions close to the source back to the extraction electrode. This allows the beam portion to become deneutralized and, therefore, unstable. The unstable beam is diminished in intensity since positively charged ions within that beam portion exit the beam. An isolation plate separates beam portions in close proximity to the extraction electrode to inhibit beam crosstalk and an additional suppression electrode common to all beam portions is controllably biased to further enhance control over beam portion intensity. In a typical application, the beam is a circular beam and intensity control is maintained to assure common intensity for a given radii from the beam center.

    摘要: The present invention discloses systems and methods for generating low energy, high current ion beams by scaling beamline dimensions and employing multiple beamlines. An array of beamlets is generated by an ion source. The beamlets then pass through a mass analysis module that permits selected ions to pass while blocking other ions and/or particles. The selected ions can then be accelerated to a desired energy level. Subsequently, the beamlets are diverged in horizontal and vertical directions to form a single low energy, high current ion beam.

The magnets may cooperatively interact to provide a multi-cusped magnetic field along at least a portion of the passageway. The multi-cusped magnetic field may be superimposed on the dipole field at a specified field strength in a region of the mass analyzer passageway for a given low energy ion beam.
