    摘要: An apparatus and method for ion implantation that include destabilizing the ion beam as it passes through magnetic field, preferably a dipole magnetic field is disclosed. By introducing a bias voltage at certain points within the magnetic field, electrons from the plasma are drawn toward the magnet, thereby causing the ion beam to expand due to space charge effects. The bias voltage can be introduced into the magnet in a region where the magnetic field has only one component. Alternatively, the bias voltage can be in a region wherein the magnetic field has two components.

    摘要: The present invention is directed to in-situ detection of particles and other such features in an ion implantation system during implantation operations to avoid such additional monitoring tool steps otherwise expended before and/or after implantation, for example. One or more such systems are revealed for detecting scattered light from particles on one or more semiconductor wafers illuminated by a light source (e.g., laser beam). The system comprises an ion implanter having a laser for illumination of a spot on the wafer and a pair of detectors (e.g., PMT or photodiode) rotationally opposite from the ion implantation operations. A wafer transport holds a wafer or wafers for translational scanning under the fixed laser spot. A computer analyzes the intensity of the scattered light detected from the illuminated wafer (workpiece), and may also map the light detected to a unique position. For example, particles or other such contaminates may be identified on wafers during the implantation process before additional time and resources are consumed, and aid in determining the sources of such contaminates. Further, threshold analysis of the quantity or size of such particles, for example, may provide a system interlock for shutdown or feedback control.

    摘要: Method and apparatus for use in treating a workpiece implantation surface by causing ions to impact the workpiece implantation surface. Ions emitted by an ion source are accelerated away from the ion source to form an ion beam. A magnetic field is created for intercepting the ions in the ion beam exiting the source and selectively deflectiing the ions away from an initial trajectory in a generally arcuate scanning motion. The magnetic field is created by synchronized energization of first and second current carrying coils located along an inner surface of a ferromagnetic support. The beam is deflected away from the initial trajectory by a controlled amount in a time varying manner to cause the beam to sweep through an arcuate path and impact the workpiece.
