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 an ion implantation procedure.

Abstract: A system and method for ion implantation is described, which includes a gas or gas mixture including at least one ionizable gas used to generate ionic species and an arc chamber that includes two or more different arc chamber materials. Using the system ionic species are generated in the arc chamber with liner combination, and one or more desired ionic species display a higher beam current among the ionic species generated, which is facilitated by use of the different materials. In turn improved implantation of the desired ionic species into a substrate can be achieved. Further, the system can minimize formation of metal deposits during system operation, thereby extending source life and promoting improved system performance.

Abstract: A hydrogenated isotopically enriched boron trifluoride (BF3) dopant source gas composition. The composition contains (i) boron trifluoride isotopically enriched above natural abundance in boron of atomic mass 11 (UB), and (ii) hydrogen in an amount of from 2 to 6.99 vol. %, based on total volume of boron trifluoride and hydrogen in the composition. Also described are methods of use of such dopant source gas composition, and associated apparatus therefor.

Abstract: Apparatus and method for use of solid dopant phosphorus and arsenic sources and higher order phosphorus or arsenic implant source material are described. In various implementations, solid phosphorus-comprising or arsenic-comprising materials are provided in the ion source chamber for generation of dimer or tetramer implant species. In other implementations, the ion implantation is augmented by use of a reactor for decomposing gaseous phosphorus-comprising or arsenic-comprising materials to form gas phase dimers and tetramers for ion implantation.

Abstract: An isotopically-enriched, boron-containing compound comprising two or more boron atoms and at least one fluorine atom, wherein at least one of the boron atoms contains a desired isotope of boron in a concentration or ratio greater than a natural abundance concentration or ratio thereof. The compound may have a chemical formula of B2F4. Synthesis methods for such compounds, and ion implantation methods using such compounds, are described, as well as storage and dispensing vessels in which the isotopically-enriched, boron-containing compound is advantageously contained for subsequent dispensing use.
