    摘要: A dual-shell architecture and methods of fabrication of fused quartz resonators is disclosed. The architecture may include two encapsulated and concentric cavities using plasma-activated wafer bonding followed by the high-temperature glassblowing. The dual-shell architecture can provide a protective shield as well as a “fixed-fixed” anchor for the sensing element of the resonators. Structures can be instrumented to operate as a resonator, a gyroscope, or other vibratory sensor and for precision operation in a harsh environment. Methods for fabricating a dual-shell resonator structure can include pre-etching cavities on a cap wafer, pre-etching cavities on a device wafer, bonding the device wafer to a substrate wafer to form a substrate pair and aligning and bonding the cap wafer to the substrate pair to form a wafer stack with aligned cavities including a cap cavity and a device cavity. The wafer stack may be glassblown to form a dual-shell structure.

    摘要: A micro-electro-mechanical systems (MEMS) autofocus actuator having a support member for supporting a lens element, the support member including a stationary portion and a movable portion, the movable portion attached to the stationary portion by a movable support beam. An electrostatic drive member is attached to the stationary portion and the movable portion to drive movement of the movable portion with respect to the stationary portion. A lens holder is suspended within the support member by a resilient arm member attached to the movable portion and a deflection beam attached to the stationary portion so that in a non-actuated state, the lens element is in a first focal position that is substantially out-of-plane with respect to the stationary portion, and in an actuated state, the lens element is in a second focal position, the second focal position being different from the first focal position.

    摘要: Aspects of the disclosure are directed to an apparatus that is used to provide a circuit layer via a supportive substrate or material layer having an upper surface and having edge surfaces configured and arranged to define patterned aperture channels. The material layer includes an array of patterned islands which provide an upper surface of the material layer for securing and supporting circuitry. The patterned islands are flexible due, for example, to patterned flexures located between and connecting the islands.
