  • GeH/Ar plasma chemistry for ion implant productivity enhancement
    Patent number: 11450504
    Abstract: A method for improving the beam current for certain ion beams, and particularly germanium and argon, is disclosed. The use of argon as a second gas has been shown to improve the ionization of germane, allowing the formation of a germanium ion beam of sufficient beam current without the use of a halogen. Additionally, the use of germane as a second gas has been shown to improve the beam current of an argon ion beam.
