Method and Apparatus for Producing Three Dimensional Nano and Micro Scale Structures

A three-dimensional milling method and apparatus is disclosed for milling micrometre and a nanometre scale three-dimensional structures. The apparatus includes an ion column (12) operable to generate a milling beam onto a substrate (20) held on an instrument stage (18). A patterning computer (22) is operable to control the ion column (12) to generate varying ion beam and/or dwell times or to produce a plurality of milling passes, in which subsequent passes overlap previous passes at least partially to create three-dimensional structures. Optionally, an SEM column (14) may be provided.
