In this paper focused ion beam milling of very shallow nanostructures in silicon and germanium by low energy Ga + ions is studied with respect to ion beam and scanning parameters. It has been found that, using low energy ions, many scanning artefacts can be avoided and, additionally, some physical effects (e.g. redeposition and ion channelling) are significantly suppressed.
