Abstract :
High-speed FIB silicon trenching is used to remove substrate materials around large structures on semiconductor devices. After removing the surrounding substrate material, it is possible to perform FIB cross-sectional analyses on structures that would normally be too large for such an approach. Through-silicon-vias (TSVs) are examined in detail, but other applications are also briefly described.
