What it is
How it works
The Thermo Fisher Scientific FEI Strata DB 235 uses a Magnum ion column with a Ga source. The Thermo Fisher Scientific FEI Strata DB 235 includes gas injection systems for Pt deposition, insulator deposition, and XeF2 enhanced etch.[1]
Where it fits in the process flow
General reference — not yet source-verifiedFocused ion beam systems are typically used after a wafer or device has already been fabricated to a stage where internal structures must be accessed, modified, or examined. Focused ion beam work commonly sits alongside failure analysis, process characterization, sample preparation, and circuit edit activities rather than high-volume patterning steps.
Applications
The Thermo Fisher Scientific FEI Strata DB 235 includes an Omniprobe manipulator for lift-out TEM. The Thermo Fisher Scientific FEI Strata DB 235 also has standard sample holders and wafer holders.[1]
