What Is Plasma FIB Pfib?
Plasma FIB (P-FIB) is a potent, versatile tool and platform for material characterization, sample preparation, and nanoscale machining. Although it leverages traditional gallium-based FIB systems, a plasma ion source delivers higher ion currents, enabling higher milling rates and enabling operation over larger areas. Plasma-FIB provides the precision cutting, polishing, and imaging of semiconductors and metals in biological tissues. Many of the diverse applications of plasma-FIB relate to the general sectors of material science, nanotechnology, and electronics.
Applications and Benefits of Plasma FIB Pfib Testing
Scope
FIB plasma is used in various fields, including semiconductor manufacturing, materials research, and failure analysis. The technique described here enables the study of material microstructure, defect analysis, and cross-sectional imaging when conventional FIB methods are not feasible due to source limitations or stringent time constraints.
Applications
- Semiconductor failure analysis and advanced node device inspection
- TEM and STEM sample preparation, including large-area lamellae
- 3D tomography and volume reconstruction of materials
- Integrated circuit delayering and backside analysis
- Microelectronics packaging analysis (TSVs, solder joints, interconnects)
- Materials science research for metals, ceramics, polymers, and composites
- MEMS and micro-mechanical device modification.
Benefits
- Enables high-speed material removal, significantly faster than Ga⁺ FIB for large-volume milling
- Allows precise cross-sectioning and trenching with minimal redeposition
- Supports deep and wide cuts while maintaining good edge quality
- Reduces beam-induced damage compared to conventional ion sources for certain materials
- Capable of processing hard, brittle, and composite materials
- Suitable for advanced nanofabrication and microstructural analysis

Plasma FIB Pfib FAQs
Plasma-focused ion beam milling scanning electron microscopy (plasma-FIB SEM) combines improved sputtering efficiency with nanometer imaging resolution at room temperature or under cryogenic conditions. This can provide fast-end pointing during 3D imaging.
Ga Ions used by DB FIB tend to attach to the sample surface; instead, Xe used by P FIB reduces sample contamination by Ga Ions. P FIB can run over large areas more than 20 times faster than DB FIB.
Focused ion beam, or FIB, is a site-specific material analysis, deposition, and ablation technique primarily employed in the semiconductor industry, materials research, and, increasingly, the biological area. An apparatus used in science that mimics an SEM is called a fiber optic bar (FIB) configuration.
