FIB

The FIB is a versatile analytical tool for materials science, semiconductor industry, etc. It is built on a FESEM platform for site-specific analysis, cross-sectioning, deposition and removal of materials, TEM lamella preparation and so on. The FIB is equipped with a Ga ion beam, Pt and C gas injection systems and an in-situ manipulator for lamella preparation and nanofabrication work.
