FIB

JEOL 4500 FIB/SEM

Equipped with two columns; a vertical 30 kV electron column with a LaB6 electron gun, and an inclined 30kV ion column with a Ga+ ion source. The focused ion beam (FIB) allows very precise cutting to be performed, and the scanning electron microscope (SEM) allows the cutting to be viewed and controlled while it is happening. In addition there is a metal deposition system; an organo-metallic gas is introduced through a tiny tube next to the region of interest, and this is broken down by secondary electrons produced by the ion beam or electron beam, giving selective deposition. Finally there is a micromanipulator, which can be attached to objects using selective metal deposition. This allows small objects to be picked up and moved. They can be fixed in place with metal deposition and the connection with the needle cut away - see the TEM prep page for an example.
