    Abstract: The current disclosure is directed to methods and assemblies configured to deliver a mixture of germanium tetrafluoride (GeF4) and hydrogen (H2) gases to an ion implantation apparatus, so H2 is present in an amount in the range of 25%-67% (volume) of the gas mixture, or the GeF4 and H2 are present in a volume ratio (GeF4:H2) in the range of 3:1 to 33:67. The use of the H2 gas in an amount in mixture or relative to the GeF4 gas prevents the volatilization of cathode material, thereby improving performance and lifetime of the ion implantation apparatus. Gas mixtures according to the disclosure also result in a significant Ge+ current gain and W+ peak reduction during au ion implantation procedure.

    Abstract: A method and system for fluorine ion implantation is described, where a fluorine compound capable of forming multiple fluorine ionic species is introduced into an ion implanter at a predetermined flow rate. Fluorine ionic species are generated at a predetermined arc power and source magnetic field, providing an optimized beam current for the desired fluorine ionic specie. The desired fluorine ionic specie, such as one having multiple fluorine atoms, is implanted into the substrate under the selected operating conditions.
