    Abstract: A terminal for an ion implantation system is provided, wherein the terminal has a terminal housing (154) for supporting an ion source (108) configured to form an ion beam. A gas box (146) within the terminal housing has a hydrogen generator (144) configured to produce hydrogen gas for the ion source. The gas box is electrically insulated from the terminal housing, and is further electrically coupled to the ion source. The ion source and gas box are electrically isolated from the terminal housing by a plurality of electrical insulators. A plurality of insulating standoffs (156) electrically isolate the terminal housing from an earth ground. A terminal power supply electrically biases the terminal housing to a terminal potential with respect to the earth ground. An ion source power supply electrically biases the ion source to an ion source potential with respect to the terminal potential. Electrically conductive tubing (148) electrically couples the gas box and ion source.

    Abstract: An ion implantation system is provided having an ion source configured to form an ion beam from aluminum iodide. A beamline assembly selectively transports the ion beam to an end station configured to accept the ion beam for implantation of aluminum ions into a workpiece. An arc chamber forms a plasma from the aluminum iodide, where arc current from a power supply is configured to dissociate aluminum ions from the aluminum iodide. One or more extraction electrodes extract the ion beam from the arc chamber. A hydrogen co-gas source further introduces a hydrogen co-gas to react residual aluminum iodide and iodide, where the reacted residual aluminum iodide and iodide is evacuated from the system.

    Abstract: Processes and systems for carbon ion implantation include utilizing phosphorous trifluoride (PF 3 ) as a co-gas with carbon oxide gas, and in some embodiments, in combination with the lanthanated tungsten alloy ion source components advantageously results in minimal oxidation of the cathode 306 and cathode shield 316. Moreover, acceptable levels of carbon deposits on the arc chamber 300 internal components have been observed as well as marked reductions in the halogen cycle, i.e., WF x formation.

    Abstract: An ion source assembly and method is provided for improving ion implantation performance. The ion source assembly has an ion source chamber and a source gas supply provides a molecular carbon source gas to the ion source chamber. An excitation source excites the molecular carbon source gas, forming carbon ions and atomic carbon. An extraction electrode extracts the carbon ions from the ion source chamber, forming an ion beam. A hydrogen peroxide co-gas supply provides hydrogen peroxide co-gas to the ion source chamber. The hydrogen peroxide co-gas decomposes and reacts with the atomic carbon, forming hydrocarbons within the ion source chamber. An inert gas is further introduced and ionized to counteract oxidation of a cathode due to the decomposition of the hydrogen peroxide. A vacuum pump removes the hydrocarbons, wherein deposition of atomic carbon is reduced and a lifetime of the ion source chamber is increased.

    Abstract: An ion source chamber 132 for an ion implementation system has a textured surfaced to reduce surface film delamination on the interior walls of the ion source chamber. The residual stresses originated from the thermal expansion mismatch due to temperature changes and the tensile residual stress between film and the substrate (liners). The textured feature alters the width to thickness ratio so that it will peel off when it reaches its fracture tensile stress. The machine textures surface increases the mechanical interlocking of the film that builds up on the surface of the ion source chamber, which delays delamination and reduces the size of the resulting flake thereby reducing the likelihood that the flake will bridge a biased component to a ground reference surface and correspondingly increases the life of the ion source 130.

    Abstract: An ion implantation system for improving performance and extending lifetime of an ion source is disclosed. A fluorine-containing dopant gas source is introduced into the ion chamber along with one or more co-gases. The one or more co-gases can include hydrogen or krypton. The co-gases mitigate the effects caused by free fluorine ions in the ion source chamber which lead to ion source failure.
