There is provided an ion generation device including a plasma generation chamber that generates a plasma for extracting an ion, and a heating device configured to heat the plasma generation chamber by irradiating a member that defines the plasma generation chamber or a member that is to be exposed to the plasma generated inside the plasma generation chamber with a laser beam.

Capacitive sensors and capacitive sensing data integration for plasma chamber condition monitoring are described. In an example, a plasma chamber monitoring system includes a plurality of capacitive sensors, a capacitance digital converter, and an applied process server coupled to the capacitance digital converter, the applied process server including a system software. The capacitance digital converter includes an isolation interface coupled to the plurality of capacitive sensors, a power supply coupled to the isolation interface, a field-programmable gate-array firmware coupled to the isolation interface, and an application-specific integrated circuit coupled to the field-programmable gate-array firmware.

The invention provides a bias voltage to the component (such as the Faraday cup) for reducing the generation of particles, such as the implanted ions and/or the combination of the implanted ions and the material of the component, and preventing particles peeling away the component. The strength of the biased voltage should not significantly affect the implantation of ions into the wafer and should significantly prevent the emission of radiation and/or electrons away the biased component. How to provide and adjust the biased voltage is not limited, both the extra voltage source and the amended Pre-Amplifier are acceptable. Moreover, due to the electric field generated by the Faraday cup is modified by the biased voltage, the ion beam divergence close to the Faraday cup may be reduced such that the potential difference between the ion beam measured by the profiler and received by the Faraday cup may be minimized.

Methods and a system of an ion implantation system are configured for increasing beam current above a maximum kinetic energy of a first charge state from an ion source without changing the charge state at the ion source. Ions having a first charge state are provided from an ion source and are selected into a first RF accelerator and accelerated in to a first energy. The ions are stripped to convert them to ions having various charge states. A charge selector receives the ions of various charge states and selects a final charge state at the first energy. A second RF accelerator accelerates the ions to final energy spectrum. A final energy filter filters the ions to provide the ions at a final charge state at a final energy to a workpiece.

The system may further include a power supply in communication with the electrostatic filter, the power supply operable to supply a voltage and a current to the first and second electrodes, wherein the variable distance between the first and second outer surfaces causes the ion beam to converge or diverge.
