Advanced Microscopy

Focused Ion Beam (FIB)

A DualBeam™ system (FEI Strata 400 STEM) is a unique precision machining tool that can be used for structure fabrication and modification, in addition, to gather microstructural information from the surface of the specimen with a high spatial resolution. FIB systems have revolutionized failure analysis in the semiconductor industry and are having an increasing impact on materials analysis in general.

Applications

• High resolution and High contrast imaging
• Cross-sectional imaging through semiconductor devices
• Failure Analysis
• Site specific specimens preparation for Transmission Electron Microscopy (TEM)
• Site specific specimens preparation for Atom Probe Tomography
• Nanofabrication and Microfabrication
• Circuit Modification
• Potential Contrast
