    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 translation: 本发明涉及用作至少部分微机电特征的模具的图案化气凝胶基层。 气凝胶的密度小于MEMS制造中使用的典型材料的密度,例如多晶硅,氧化硅,单晶硅,金属,金属合金等。 因此,可以以明显高于在较致密的材料中形成结构特征的速率的速率在气凝胶层中形成结构特征。 本发明还包括一种图案化气凝胶层以产生这种基于气凝胶的模具的方法。 本发明还包括使用基于气凝胶的模具制造微机电特征的方法。 该方法包括将致密材料层直接沉积在已经形成在气凝胶层中的微机电特征的至少一部分的轮廓上。
