Unfortunately, surfaces milled by Xe plasma FIB may cause undesirable curtaining artefacts on the cross-section, similar to Ga FIB at very high beam currents, when a composite material is processed.
In milling, inefficiency rarely manifests itself suddenly. More often, it is the result of non-optimized energy consumption, ...
It’s easy to assume that not much has changed with face mills for a while. There’s been so much attention on other milling processes over the last few years, and face mills, or shell mills, were ...
