    • There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a MEMS device, and technique of fabricating or manufacturing a MEMS device, having mechanical structures encapsulated in a chamber prior to final packaging. An embodiment further includes a buried polysilicon layer and a "protective layer" deposited over the buried polysilicon layer to prevent possible erosion of, or damage to the buried polysilicon layer during processing steps. The material that encapsulates the mechanical structures, when deposited, includes one or more of the following attributes: low tensile stress, good step coverage, maintains its integrity when subjected to subsequent processing, does not significantly and/or adversely impact the performance characteristics of the mechanical structures in the chamber (if coated with the material during deposition), and/or facilitates integration with high-performance integrated circuits. In one embodiment, the material that encapsulates the mechanical structures is, for example, silicon (polycrystalline, amorphous or porous, whether doped or undoped), silicon carbide, silicon-germanium, germanium, or gallium-arsenide.

    • A mechanical structure is disposed in a chamber, at least a portion of which is defined by the encapsulation structure. A first method provides a channel cap having at least one preform portion disposed over or in at least a portion of an anti-stiction channel to seal the anti-stiction channel, at least in part. A second method provides a channel cap having at least one portion disposed over or in at least a portion of an anti-stiction channel to seal the anti-stiction channel, at least in part. The at least one portion is fabricated apart from the electromechanical device and thereafter affixed to the electromechanical device. A third method provides a channel cap having at least one portion disposed over or in at least a portion of the anti-stiction channel to seal an anti-stiction channel, at least in part. The at least one portion may comprise a wire ball, a stud, metal foil or a solder preform. A device includes a substrate, an encapsulation structure and a mechanical structure. An anti-stiction layer is disposed on at least a portion of the mechanical structure. An anti-stiction channel is formed in at least one of the substrate and the encapsulation structure. A cap has at least one preform portion disposed over or in at least a portion of the anti-stiction channel to seal the anti-stiction channel, at least in part.
