Abstract:
A focused ion beam system includes a gas ion source and an emitter structure. The emitter structure includes a pair of conductive pins fixed to a base member, a filament connected between the pair of conductive pins, and an emitter which has a tip end with one atom or three atoms and which is connected to the filament. A supporting member is fixed to the base material, and the emitter is connected to the supporting member.
