    摘要: An ion implanter includes a source of a stationary, planar ion beam, a set of beamline components that steer the ion beam along a normal beam path as determined by first operating parameter values, an end station that mechanically scans the wafer across the normal beam path, and control circuitry that responds to a glitch in the ion beam during implantation pass to (1) immediately alter an operating parameter of at least one of the beamline components to a second value to direct the ion beam away from the normal beam path and thereby cease implantation at an implantation transition location on the wafer, (2) subsequently move the wafer to an implantation-resuming position in which the implantation transition location on the wafer lies directly on the normal path of the ion beam, and (3) return the operating parameter to its first value to direct the ion beam along the normal beam path and resume ion implantation at the implantation transition location on the wafer. The operating parameter may be an output voltage of an extraction power supply, or other voltages and/or currents of beamline components that affect the path of the ion beam.

    摘要: Methods of ion implantation and ion sources used for the same are provided. The methods involve generating ions from a source feed gas that comprises multiple elements. For example, the source feed gas may comprise boron and at least two other elements (e.g., XaBbYc). The use of such source feed gases can lead to a number of advantages over certain conventional processes including enabling use of higher implant energies and beam currents when forming implanted regions having ultra-shallow junction depths. Also, in certain embodiments, the composition of the source feed gas may be selected to be thermally stable at relatively high temperatures (e.g., greater than 350° C.) which allows use of such gases in many conventional ion sources (e.g., indirectly heated cathode (IHC), Bernas) which generate such temperatures during use.

    摘要: Techniques for preventing parasitic beamlets from affecting ion implantation are disclosed. In one particular exemplary embodiment, the techniques may be realized as an apparatus for preventing parasitic beamlets from affecting ion implantation. The apparatus may comprise a controller that is configured to scan a spot beam back and forth, thereby forming an ion beam spanning a predetermined width. The apparatus may also comprise an aperture mechanism that, if kept stationary, allows the spot beam to pass through. The apparatus may further comprise a synchronization mechanism, coupled to the controller and the aperture mechanism, that is configured to cause the aperture mechanism to move in synchronization with the scanned spot beam, allowing the scanned spot beam to pass through but blocking one or more parasitic beamlets associated with the spot beam.
