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.

Abstract: An integrated gas box is disclosed. The integrated gas box is an enclosure, wherein one wall of the enclosure includes an aperture. A bushing is affixed to the exterior of this wall. The distal end of the bushing has a flange that is affixed to a wall of the vacuum chamber. The ion source is introduced into the bushing through an access door in the enclosure and slides into the aperture. The base flange of the ion source is sufficiently large such that it cannot pass through the aperture and forms a seal between the bushing and the interior of the integrated gas box. The integrated gas box includes the gas canisters and associated valves which are used to supply feed gas and diluent gasses to the ion source. The integrated gas box also houses the power supplies used to bias the components within the ion source.

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 left electrically unconnected in certain embodiments and are grounded in other embodiments. The floating side electrodes may be beneficial in the formation of certain species. In certain embodiments, a relay is used to allow the side electrodes to be easily switched between these two modes. By changing the configuration of the side electrodes, 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 left floating relative to the chamber. In certain embodiments, a controller is in communication with the relay so as to control which mode is used, based on the desired feed gas.
