FIB and dual beam, theory and applicationssecondary electrons is collected by detector to form a secondary ion image or secondary electron image. • FIB is a milling machine. The milling is site specific. The. Gallium (Ga+) primary ion beam strikes the sample surface removing material through the physical sputting of sample material. • FIB can deposit metals and.appli ion form of bells mills,Scanning Electron Microscopy (SEM) and Focused Ion Beams (FIB .Many Applications: One of most widely employed microscopy techniques other than optical microscopy. Surface topography / morphology. Composition analysis ... (e.g. milling). The detector collects secondary electrons or ions to form an image. For deposition and enhanced etching: gases can be injected to the system.Focused Ion Beam Microscopy and Micromachining - UCLA Nanolabenabling the beam to be tightly focused. The ion source type used in all com- mercial systems and in the majority of research systems designed with microma- chining applications in mind is the liquid- metal ion source (LMIS).6,7 Of the existing ion source types, the LMIS provides the brightest and most highly focused beam.
