Abstract

A micro structure includes a silicon substrate, an adhesion layer on the silicon substrate, a bias layer on the adhesion layer, and structure layers on the adhesion layer. The two or more structure layers comprise different material compositions and a plurality of holes through at least two of the structure layers. Widths of the plurality of holes are in the range of 0.5-500 nm.
