    摘要: An ion source (26) includes a plasma confinement chamber and a plasma electrode (70) forming a generally planar wall section of the plasma confinement chamber. The plasma electrode (70) has at least one opening (84, 86) for allowing an ion beam (88) to exit the confinement chamber and has a set of magnets (78, 80, 82) that generate a magnetic field extending across the openings (84, 86) in the plasma electrode (70). The openings (84, 86) in the plasma electrode (70) can be fashioned as elongated slots or circular openings aligned along the axis. The ion source (26) can further include a power supply (72) for negatively biasing the plasma electrode relative to the plasma confinement chamber and an insulator (74) for electrically insulating the plasma electrode (70). Cooling tubes can also be provided to transfer heat away from the magnets in the plasma electrode (70).

    摘要: A high throughput ion implantation system that rapidly and efficiently processes large quantities of flat panel displays. The ion implantation system has an ion chamber generating a stream of ions, a plasma electrode having an elongated slot with a high aspect ratio for shaping the stream of ions into a ribbon beam, and an electrode assembly for directing the stream of ions towards a workpiece. The plasma electrode can include a split extraction system having a plurality of elongated slots oriented substantially parallel to each other. The ion implantation system can also have a diffusing system for homogenizing the ion stream. Various exemplary diffusing systems include an apertured plate having an array of openings, diffusing magnets, diffusing electrodes, and dithering magnets.

    摘要: A magnetic filter (90) for an ion source (26) is provided. The ion source comprises a housing defining a plasma confinement chamber (76) in which a plasma including ions is generated by ionizing a source material. The housing includes a generally planar wall (50) in which are formed a plurality of elongated apertures (64) through which an ion beam (84) may be extracted from the plasma. The plurality of elongated openings are oriented substantially parallel to each other and to a first axis (66) which lies within the planar wall the first axis being substantially orthogonal to a second axis (68) which also lies within the planar wall. The magnetic filter (90) is disposed within the plasma confinement chamber (76). The magnetic filter separates the plasma confinement chamber into a primary region (86) and a secondary region (88). The magnetic filter comprises a plurality of parallel elongated magnets (90a-90n), oriented at an angle .theta. as measured from the second axis (68), and lying in a plane which is generally parallel to the generally planar wall (50).

    摘要: An attenuator (90) for an ion source (26) is provided. The ion source comprises a plasma chamber (76) in which a gas is ionized by an exciter (78) to create a plasma which is extractable through at least one aperture (64) in an apertured portion (50) of the chamber to form an ion beam. The attenuator (90) comprises a member (90) positioned within the chamber (76) intermediate the exciter (78) and the at least one aperture (64), the member providing at least one first opening (97) corresponding the at least one aperture (64), and being moveable between first and second positions with respect to the at least one aperture. In one embodiment, in the first position, the member is positioned adjacent the aperture (64) to obstruct at least a portion of the aperture, and in the second position the member is positioned away from the aperture (64) so as not to obstruct the aperture. In a second embodiment, the aperture (64) resides in an aperture plate (50) and (i) the member and the aperture plate form a generally closed region (102) between the aperture plate and the chamber (76) when the member is in the first position, and (ii) the aperture (64) is in direct communication with the chamber (76) when the member is in the second position. In this second embodiment, plasma within the chamber (76) diffuses through the region (102) before being extracted through the aperture in the first position, and plasma within the chamber is extracted directly through the aperture in the second position.
