Abstract:
1. A method of fabricating a microelectromechanical structure, the method comprising: providing a substrate having an aerogel-based layer over a portion of the substrate, the aerogel-based layer comprising an aerogel that is at least about 85% gas by volume; writing a structural feature in the aerogel-based layer, the structural feature having a surface contour that is substantially the same as a surface contour of at least a part of a microelectromechanical feature; depositing a dense material layer over the aerogel-based layer to form at least part of the microelectromechanical feature, wherein a portion of the dense material layer is directly attached to another portion of the substrate; and removing the aerogel-based layer.
