What is FIB Cross Section Technology?
FIB Cross Section Technology, or Focused Ion Beam cross-sectioning, is a precise technique used to examine the fine details of materials. It involves directing a finely focused beam of ions onto a sample to mill away layers, creating ultra-thin sections for inspection under electron microscopes. This allows researchers to reveal hidden features within a material’s microstructure by removing specific areas layer by layer.
Used extensively in semiconductor manufacturing and materials science, FIB Cross Section provides valuable insights into device integrity and failure analysis.
