Focused ion beam, also known as FIB, is a technique used particularly in the semiconductor industry, materials science and increasingly in the biological field for site-specific analysis, deposition, and ablation of materials.A FIB setup is a scientific instrument that resembles a scanning electron microscope (SEM).

However, while the SEM uses a focused beam of electrons to image the sample in. The focused ion beam (FIB) system is an important tool for understanding and manipulating the structure of materials at the nanoscale.

Combining this system with an electron beam creates a DualBeam - a single system that can function as an imaging, analytical and sample modification tool.
