Abstract:
1. A method of making an electromechanical device, comprising: forming a sacrificial layer over a substrate; forming two or more substantially parallel first channels in the sacrificial layer to thereby form at least one strip of the sacrificial layer; forming support rails in the formed first channels; forming a first elongated opening in the strip of the sacrificial layer; forming an elongated post in the first elongated opening; forming a deformable layer over the sacrificial layer, the support rails and the elongated post; forming one or more second channels in the deformable layer to thereby form at least one strip of the deformable layer, the strip of the deformable layer being substantially perpendicular to the strip of the sacrificial layer; and removing the sacrificial layer to form a cavity between the strip of the deformable layer and the substrate, the cavity being bordered on two sides by the support rails; wherein the support rails support the deformable layer on the two sides of the cavity; wherein the elongated post is within the cavity; and wherein the elongated post is aligned so that the elongate direction is substantially parallel to the substrate and to the support rails.
