Methods for beam current modulation by ion source parameter modulation

Beam current is adjusted during ion implantation by adjusting one or more parameters of an ion source. The ion beam is generated or provided by a non-arc discharge based ion source, such as an electron gun driven ion source or an RF driven ion source. A beam current adjustment amount is determined....

Zusammenfassung:Beam current is adjusted during ion implantation by adjusting one or more parameters of an ion source. The ion beam is generated or provided by a non-arc discharge based ion source, such as an electron gun driven ion source or an RF driven ion source. A beam current adjustment amount is determined. Then, one or more parameters of the ion source are adjusted according to the determined beam current adjustment amount. The beam current is provided having a modulated beam current.
