摘要:A micro-electro-mechanical device including a first substrate; a first contactdisposed on a first surface of the substrate; a piezoelectric actuator disposed over the

first surface of the substrate; a second contact coupled to the actuator and disposed inproximity to the first contact; a gap control mechanism disposed between the substrateand the actuator for limiting movement of the first contact relative to the secondcontact. In the exemplary embodiment, the gap control mechanism is a gap control stopconstructed of dielectric material. In practice, plural stops are used. In the exemplaryembodiment, plural thermosonic bonds are used to connect the actuator to the firstsubstrate. A second substrate is disposed over the piezo-electric actuator. The secondsubstrate has wells over the bonds to facilitate application of a bonding tool to thebonds. The gap control mechanism provides consistent height control between a flippedchip and its base substrate without exposing the assembly to high temperatures.
