A HYBRID MAGNETIC/ELECTROSTATIC DEFLECTOR FOR ION IMPLANTATION SYSTEMS |
摘要 |
A magnetic deflector for an ion beam is disclosed and comprises first and second coils. The coils are positioned above and below the beam, respectively, and extend along a width of the beam. Current passes through the coils to generate a magnetic field therebetween that is generally perpendicular to a direction of travel of the beam along substantially the entire width thereof. In another aspect of the invention, a method of deflecting a beam prior to implantation into a workpiece is disclosed. The method includes determining one or more properties associated with the beam and selectively activating one of a magnetic deflection module and an electrostatic deflection module based on the determination. Plasma may be introduced for reducing space charge. |
