ENDPOINTING FOR FOCUSED ION BEAM PROCESSING

To expose a desired feature, focused ion beam milling of thin slices from a cross section alternate with forming a scanning electron image of each newly exposed cross section. Milling is stopped when automatic analysis of an electron beam image of the newly exposed cross section shows that a pre-det...
