    Abstract: A device 20 includes a substrate 22 coupled with a substrate 24 such that a volume 32 is formed between the substrates 22, 24. Contact posts 48, 50 on the substrate 22 and a cantilever beam structure 36 on the substrate 24 are located within the volume 32. The cantilever beam structure has a conductive trace 38 that is selectively contactable with the contact posts 48, 50 to yield a microelectromechanical (MEMS) switch within the volume 32. Fabrication methodology for making the contact posts 48, 50 entails forming post protrusions 68, 70 on the substrate 22 and shaping post protrusions 68, 70 so that they acquire a rounded shape. Input and output signal lines 42, 44 are constructed such that respective portions of input and output signal lines 42, 44 overly corresponding post protrusions 68, 70 and take on the shape of post protrusions 68, 70.

Semiconductor dies (22) on the device wafer (20) each include a microelectronic device (26) and terminal elements (28, 30). Barriers (36, 52) are positioned in inactive regions (32, 50) of the device wafer (20). The cap wafer (60) is coupled to the device wafer (20) and covers the semiconductor dies (22). Portions (72) of the cap wafer (60) are removed to expose the terminal elements (28, 30). The barriers (36, 52) may be taller than the elements (28, 30) and function to prevent the portions (72) from contacting the terminal elements (28, 30) when the portions (72) are removed. The wafer structure (88) is singulated to form multiple semiconductor devices (89), each device (89) including the microelectronic device (26) covered by a section of the cap wafer (60) and terminal elements (28, 30) exposed from the cap wafer (60).

    Abstract: A MEMS capacitive device (90) includes a fixed capacitor plate (104) formed on a surface (102) of a substrate (100). A movable capacitor plate (114) is suspended above the fixed capacitor plate (104) by compliant members (116) anchored to the surface (102). A movable element (120) is positioned in spaced apart relationship from the movable capacitor plate (104) and has an actuator (130) formed thereon. Actuation of the actuator (130) causes abutment of a portion of the movable element (120) against a contact surface (136) of the movable plate (114). The abutment moves the movable plate (114) toward the fixed plate (104) to alter a capacitance (112) between the plates (104, 114). Another substrate (118) may be coupled to the substrate (100) such that a surface (126) of the substrate (118) faces the surface (102) of the substrate (100). The movable element (120) may be formed on the surface (126).

    Abstract: MEMS piezoelectric switches 100 that provide advantages of compact structure ease of fabrication in a single unit, and that are free of high temperature-induced morphological changes of the contact materials and resultant adverse effects on properties. High temperature-induced morphological changes refer to changes that occur during fabrication when metallic contacts such as radio frequency lines 125, 130 and shorting bars 150 are exposed to temperatures required to anneal a piezoelectric layer or those temperatures encountered during high temperature deposition of the piezoelectric layer, if such process is used instead.
