Latest Patents
Raymond Callahan holds a patent for a system, method, and program product titled "Determining ion beam parallelism using refraction method." This invention provides a novel approach to determining the parallelism of an ion beam by utilizing a refraction method. One embodiment of the invention involves determining a first test position of the ion beam without exposing it to an acceleration/deceleration electrical field. It then determines a second test position while exposing the ion beam to such a field. The parallelism of the ion beam is assessed based on the differences between these two test positions. The acceleration/deceleration electrical field refracts the ion beam, magnifying any non-parallelism, which can be quantified to improve ion implanter systems.
