Abstract: Micromachined ultrasonic transducers integrated with complementary metal oxide semiconductor (CMOS) substrates are described, as well as methods of fabricating such devices. Fabrication may involve two separate wafer bonding steps. Wafer bonding may be used to fabricate sealed cavities in a substrate. Wafer bonding may also be used to bond the substrate to another substrate, such as a CMOS wafer. At least the second wafer bonding may be performed at a low temperature.

Abstract: A multiple coil spring MEMS resonator includes a center anchor and a resonator body including two or more coil springs extending in a spiral pattern from the center anchor to an outer closed ring. Each pair of coil springs originates from opposing points on the center anchor and extends in the spiral pattern to opposing points on the outer ring. The number of coil springs, the length and the width of the coil springs and the weight of the outer ring are selected to realize a desired resonant frequency.

Abstract: A system and/or method for utilizing MEMS switching technology to operate MEMS sensors. As a non-limiting example, a MEMS switch may be utilized to control DC and/or AC bias applied to MEMS sensor structures. Also for example, one or more MEMS switches may be utilized to provide drive signals to MEMS sensors (e.g., to provide a drive signal to a MEMS gyroscope).

Abstract: An integrated circuit (IC) device is provided. The IC device includes a first die including a first substrate and a second die including a second substrate. A plasma-reflecting layer is included on an upper surface of the first die. The plasma-reflecting layer is configured to reflect a plasma therefrom. The second substrate is bonded to the first die so as to form a cavity, wherein a lower surface of the cavity is lined by the plasma-reflecting layer. A dielectric protection layer is present on a lower surface of the second die and lines the upper surface of the cavity. A material of the second substrate has a first etch rate for the plasma and a material of the dielectric protection layer has a second etch rate for the plasma. The second etch rate is less than the first etch rate.
