High current density particle beam system
摘要:
The present invention relates to charged particle beam devices. The devices comprise an emitter for emitting charged particles; an aperture arrangement with at least two apertures for separating the emitted charged particles into at least two independent charged particle beams; and an objective lens for focusing the at least two independent charged particle beams, whereby the independent charged particle beams are focused onto the same location within the focal plane.
