3.4.4. Ion optics (FIB column)

Fig. 3.4: Schematics of the ion optics

The focused ion beam (FIB) column is the part of the CrossBeam

®

workstation, where ions are

emitted, accelerated, focused and deflected.
The FIB column is tilted by 54°.

Ion source

A liquid metal ion source of gallium (Ga

+

) serves as ion source (

1

).

Gallium ions (Ga

+

) are extracted from a liquid metal ion source. The ions are accelerated by the

acceleration voltage to an energy of maximum 30 keV. The ion emission is regulated by the ex-
tractor and stabilised by the suppressor.

Gallium is used up during operation. Therefore, the gallium emitter cartridge is a consumable.
Moreover, the gallium emitter has to be regenerated by heating from time to time; the heating pro-
cedure removes the gallium oxide, which has been created during operation.
