Abstract: 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.
