Abstract: An apparatus, system and method. An apparatus may include an RF power assembly, arranged to output an RF signal; a resonator, coupled to receive the RF signal, the resonator comprising a first output end and a second output end, and a drift tube assembly, configured to transmit an ion beam, and coupled to the resonator. As such, the drift tube assembly may include a first AC drift tube electrode, coupled to the first output end, and a second AC drift tube electrode, coupled to the second output end and separated from the first AC drift tube by a first gap. The RF power assembly may be switchable to switch output from a first Eigenmode frequency to a second Eigenmode frequency.

Abstract: An IHC ion source that employs a negatively biased cathode and one or more side electrodes is disclosed. The one or more side electrodes are biased using an electrode power supply, which supplies a voltage of between 0 and −50 volts, relative to the chamber. By adjusting the output from the electrode power supply, beam current can be optimized for different species. For example, certain species, such as arsenic, may be optimized when the side electrodes are at the same voltage as the chamber. Other species, such as boron, may be optimized when the side electrodes are at a negative voltage relative to the chamber. In certain embodiments, a controller is in communication with the electrode power supply so as to control the output of the electrode power supply, based on the desired feed gas.

Abstract: Provided herein are approaches for increasing operational range of an electrostatic lens. An electrostatic lens of an ion implantation system may receive an ion beam from an ion source, the electrostatic lens including a first plurality of conductive beam optics disposed along one side of an ion beam line and a second plurality of conductive beam optics disposed along a second side of the ion beam line. The ion implantation system may further include a power supply in communication with the electrostatic lens, the power supply operable to supply a voltage and a current to at least one of the first and second plurality of conductive beam optics, wherein the voltage and the current deflects the ion beam at a beam deflection angle, and wherein the ion beam is accelerated and then decelerated within the electrostatic lens.
