Abstract:
A method for fabricating a trilayered beam, comprising:(a) depositing a sacrificial layer on a substrate; (b) depositing a first conductive layer on the sacrificial layer; (c) forming a first conductive microstructure by removing a portion of the first conductive layer; (d) depositing a structural layer on the first conductive microstructure and the sacrificial layer; (e) forming a via through the structural layer to the first conductive microstructure; (f) depositing a second conductive layer on the structural layer and in the via; (g) forming a second conductive microstructure by removing a portion of the second conductive layer, wherein the second conductive microstructure electrically communicates with the first conductive microstructure through the via; and (h) removing a sufficient amount of the sacrificial layer so as to separate the first conductive microstructure from the substrate, wherein the structural layer is supported by the substrate at a first end and is freely suspended above the substrate at an opposing second end.
