    Abstract: An electrode assembly for use with an ion source chamber or as part of an ion implanter processing system to provide a uniform ion beam profile. The electrode assembly includes an electrode having an extraction slot with length L aligned with an aperture of the ion source chamber for extracting an ion beam. The electrode includes a plurality of segments partitioned within the length of the extraction slot where each of the segments is configured to be displaced in at least one direction with respect to the ion beam. A plurality of actuators are connected to the plurality of electrode segments for displacing one or more of the segments. By displacing at least one of the plurality of electrode segments, the current density of a portion of the ion beam corresponding to the position of the segment within the extraction slot is modified to provide a uniform current density beam profile associated with the extracted ion beam.

    Abstract: In a cleaning process for an ion source chamber, an electrode positioned outside of the ion source chamber includes a suppression plug. When the cleaning gas is introduced into the source chamber, the suppression plug may engage an extraction aperture of the source chamber to adjust the gas pressure within the chamber to enhance chamber cleaning via plasma- enhanced chemical reaction. The gas conductance between the source chamber aperture and the suppression plug can be adjusted during the cleaning process to provide optimum cleaning conditions and to exhaust unwanted deposits.

    Abstract: A system, method and program product for determining parallelism of an ion beam using a refraction method, are disclosed. One embodiment includes determining a first test position of the ion beam while not exposing the ion beam to an acceleration/deceleration electrical field, determining a second test position of the ion beam while exposing the ion beam to an acceleration/deceleration electrical field, and determining the parallelism of the ion beam based on the first test position and the second test position. The acceleration/deceleration electrical field acts to refract the ion beam between the two positions when the beam is not parallel, hence magnifying any non-parallelism. The amount of refraction, or lateral shift, can be used to determine the amount of non-parallelism of the ion beam. An ion implanter system and adjustments of the ion implanter system based on the parallelism determination are also disclosed.
