摘要： The present invention relates, in general, to a method for three-dimensional (3D) microfabrication of complex, high aspect ratio structures with arbitrary surface height profiles in metallic materials, and to devices fabricated in accordance with this process. The method builds upon anisotropic deep etching methods for metallic materials previously developed by the inventors by enabling simplified realization of complex, non-prismatic structural geometries composed of multiple height levels and sloping and/or non-planar surface profiles. The utility of this approach is demonstrated in the fabrication of a sloping electrode structure intended for application in bulk micromachined titanium micromirror devices, however such a method could find use in the fabrication of any number of other microactuator, microsensor, microtransducer, or microstructure devices as well.
