FIB (Focused Ions Beam) is an etching system extremely fine with a precision of the magnitude of ten nanometers. At Intraspec, we dispose of two different systems with relatively identical working principles, but with different ions sources: the “classical” FIB, using gallium ions, and the Plasma-FIB, using Xenon plasma. In both cases, ions impact on the sample surface at very high speed, milling matter from the targeted area. Milling speed is 20 times higher in a P-FIB, allowing for bigger section areas. Standard FIB can, under specific conditions, have higher resolution.
Several operations can be performed using these two complementary systems: TEM lamellas production, material depositions, circuit editing, microsectioning. It is also possible to perform a set of microsections, with a step of approximately 10-15nm, to obtain a 3D reconstruction of the analysed area using information gathered through the chosen technique (SE, BSE, EDS, EBSD).
