  • Publication number: 20240379320
    Abstract: An ion implantation system and related methods are provided herein. An ion implantation system comprises a gas supply assembly comprising at least one gas supply vessel in fluid communication with an arc chamber. The gas supply assembly is configured to supply a gas component comprising at least one of GeF4, GeH4, H2, a fluorine-containing gas, or any combination thereof. When the gas component is supplied from the at least one gas supply vessel to the arc chamber for implantation into a substrate, a beam current of Ge ions generated from the gas component is greater than a beam current of Ge ions generated from a control gas component.

  • Patent number: 11827973
    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.

  • Patent number: 11682540
    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 system and method for fluorine ion implantation is described, which includes a fluorine gas source used to generate a fluorine ion species for implantation to a subject, and an arc chamber that includes one or more non-tungsten materials (graphite, carbide, fluoride, nitride, oxide, ceramic). The system minimizes formation of tungsten fluoride during system operation, thereby extending source life and promoting improved system performance. Further, the system can include a hydrogen and/or hydride gas source, and these gases can be used along with the fluorine gas to improve source lifetime and/or beam current.

  • Publication number: 20220290812
    Abstract: A gas storage and dispensing container includes a storage vessel, a first gas pressure regulator, and a second gas pressure regulator. The storage vessel is configured to contain a pressurized gas. The gas storage and dispensing container has a discharge flow path for discharging the pressurized gas. The first gas pressure regulator is disposed within the storage vessel, and the second gas pressure regulator is external to the storage vessel. The discharge flow path extends through the first gas pressure regulator and the second gas pressure regulator. A method of discharging gas from a gas storage and dispensing container includes a first gas pressure regulator reducing a pressure of the pressurized gas to a first pressure and a second gas pressure regulator reducing the pressure of the pressurized gas to a second pressure.
