This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
The Thermo Fisher Scientific / FEI Helios G 4 FIB-SEM is a Focused Ion Beam - Scanning Electron Microscope (FIB-SEM) tool. The Thermo Fisher Scientific / FEI Helios G 4 FIB-SEM supports 12-inch wafer sizes. The Thermo Fisher Scientific / FEI Helios G 4 FIB-SEM is classified under the Metrology & Inspection category.[1][2]
What it is
The Thermo Fisher Scientific FEI Helios G 4 is a FIB-SEM (Focused Ion Beam - Scanning Electron Microscope) system categorized as metrology and inspection equipment.[1][2]
How it works
General reference — not yet source-verifiedThe focused ion beam (typically gallium) is used to sputter material for site-specific milling, cross-sectioning, or deposition, while the scanning electron beam provides high-resolution imaging of the same region without damaging the sample.
The two beams are aligned to converge at the same point on the sample, allowing real-time observation of the ion-beam process via the electron beam.
Where it fits in the process flow
General reference — not yet source-verifiedThe tool receives wafers or coupons from upstream process steps such as lithography, etch, or deposition, and provides data for downstream sample preparation techniques like transmission electron microscopy (TEM) lamella creation.
Applications
General reference — not yet source-verifiedApplications include cross-sectioning of integrated circuits for structural analysis, preparation of thin lamellae for TEM, voltage contrast imaging for defect localization, and circuit editing for design debug.
Outside semiconductor fabs, the system is also used in materials science, forensics, and biological sample preparation where nanoscale milling and imaging are required.
