    摘要: An ion beam tuning method, system and program product for tuning an ion implanter system are disclosed. The invention obtains an ion beam profile of the ion beam by, for example, scanning the ion beam across a profiler that is within an implant chamber; and tunes the ion implanter system to maximize an estimated implant current based on the ion beam profile to simultaneously optimize total ion beam current and ion beam spot width, and maximize implant current. In addition, the tuning can also position the ion beam along a desired ion beam path based on the feedback of the spot beam center, which improves ion implanter system productivity and performance by reducing ion beam setup time and provides repeatable beam angle performance for each ion beam over many setups.

    摘要: A system, method and program product for determining contamination of an ion beam are disclosed. In the event of an isobaric interference, or near isobaric interference between a contaminant ion and an expected ion of an ion beam, which is difficult to detect, it is possible to measure a third ion in the ion beam and estimate, based on the amount of the third ion measured, a relative amount of the contaminant ion compared to the expected ion. The estimated relative amount of the contaminant ion is used together with a measured mass resolution of the ion implantation system to determine whether an ion implantation process needs to be suspended.

    摘要: An angle measurement system for an ion beam includes a flag defining first and second features, wherein the second feature has a variable spacing from the first feature, a mechanism to translate the flag along a translation path so that the flag intercepts at least a portion of the ion beam, and a sensing device to detect the ion beam for different flag positions along the translation path and produce a sensor signal having a first signal component representative of the first feature and a second signal component representative of the second feature. The first and second signal components and corresponding positions of the flag are representative of an angle of the ion beam in a direction orthogonal to the translation path. The sensing device may be a two-dimensional array of beam current sensors. The system may provide measurements of horizontal and vertical beam angles while translating the flag in only one direction.

The invention utilizes multiple faraday cups to measure a profile of at least a portion of the ion beam. The results of the measurement are then processed to determine parallelism and/or direction integrity of the ion beam. The results of the parallelism and/or direction integrity determination are then used to adjust the ion implanter system operating parameters to control parallelism and the direction of the ion beam.

    摘要: A method and apparatus for weakening a strong focus effect of an acceleration-deceleration column of an ion implanter during a deceleration mode are disclosed. The apparatus includes a tube lens surrounding the ion beam adjacent to a deceleration lens of the acceleration-deceleration column. The tube lens causes a defocusing of the ion beam at the entrance of the tube lens, which reduces the ion dispersion problem generated by the column. The invention also includes an accel-decel column and ion implanter incorporating the tube lens. An additional deceleration-suppression electrode may also be added subsequent to the tube lens for confining electrons within the tube lens.
