  • Patent number: 9177750
    Abstract: Various embodiments provide an ion source device and a method for providing the ion source. An exemplary ion source device can include an arc chamber, a filament, a reflector, a slit outlet, a source gas inlet, and/or a cleaning gas inlet. The filament can be configured to generate thermo-electrons in the arc chamber. The reflector can be configured to reflect the thermo-electrons back to the arc chamber. The slit outlet can be configured to exit a gaseous material out of the arc chamber. The source gas inlet and the cleaning gas inlet can be located on a same sidewall of the arc chamber configured to respectively introduce an ion source gas and an inert cleaning gas into the arc chamber.
