Abstract:
A method for fabricating a three-dimensional element from an anisotropic material having opposing surfaces and edge surfaces joining the opposing surfaces, comprising the steps of:(a) forming an anisotropic thin film having a bridge on a substrate; and (b) mounting the substrate onto a sample holder having a planar mounting surface extending in two dimensions and a central axis extending through one of the two dimensions; (c) rotating the sample holder about the central axis to bring, in succession, at least one of the opposing surfaces and an edge surface into position facing a focused ion-beam source, and (d) machining at least the one opposing surface and an edge surface of the bridge with a focused-ion-beam from the source, as the one opposing surface and the bridge end surface are brought into position facing the source.
