    Abstract: The invention is directed to a patterned aerogel-based layer that serves as a mold for at least part of a microelectromechanical feature. The density of an aerogel is less than that of typical materials used in MEMS fabrication, such as poly-silicon, silicon oxide, single-crystal silicon, metals, metal alloys, and the like. Therefore, one may form structural features in an aerogel-based layer at rates significantly higher than the rates at which structural features can be formed in denser materials. The invention further includes a method of patterning an aerogel-based layer to produce such an aerogel-based mold. The invention further includes a method of fabricating a microelectromechanical feature using an aerogel-based mold. This method includes depositing a dense material layer directly onto the outline of at least part of a microelectromechanical feature that has been formed in the aerogel-based layer.

    Abstract: Methods of fabricating comb drive devices utilizing one or more sacrificial etch-buffers are disclosed. An illustrative fabrication method may include the steps of etching a pattern onto a wafer substrate defining one or more comb drive elements and sacrificial etch-buffers, liberating and removing one or more sacrificial etch-buffers prior to wafer bonding, bonding the etched wafer substrate to an underlying support substrate, and etching away the wafer substrate. In some embodiments, the sacrificial etch-buffers are removed after bonding the wafer to the support substrate. The sacrificial etch-buffers can be provided at one or more selective regions to provide greater uniformity in etch rate during etching. A comb drive device in accordance with an illustrative embodiment can include a number of interdigitated comb fingers each having a more uniform profile along their length and/or at their ends, producing less harmonic distortion during operation.
