Abstract:
1. A device, comprising: a substrate having one or more vias extending therethrough that are filled with an electrically conductive material that is electrically connected to one or more layers below the substrate; a wall coupled to the substrate and extending in a direction perpendicular to a top surface of the substrate; a roof coupled to the wall such that the wall, roof and substrate collectively enclose a cavity; a cantilever structure enclosed within the cavity, movable within the cavity, and coupled to the electrically conductive material, the cantilever structure comprising a multilayer structure having a first layer of a material that has a first recombination coefficient and a second layer that faces the roof, the second layer comprising a material that has a second recombination coefficient that is lower than the first recombination coefficient, and a plurality of posts.
