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： Actuators (140), which are a pair of members, are disposed one on either side of a movable frame (120) in the X-axis direction, and oscillate the movable frame (120) about the X axis in relation to a fixed frame (110) by deformation caused by stretching and contracting of piezoelectric elements. Actuators (150), which are a pair of members, are disposed one on either side of a mirror (130) in the Y-axis direction, and oscillate the mirror (130) about the Y axis in relation to the movable frame (120) by deformation caused by stretching and contracting of the piezoelectric elements. The length of each actuator (140) extending in the Y-axis direction is longer than a distance between an inner side of the fixed frame (110) to which the actuator (140) is connected and the middle point of an outer side of the movable frame (120) in the Y-axis direction.

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.

摘要： A no-gel sensor package is disclosed. In one embodiment, the package includes a microelectromechanical system (MEMS) die having a first substrate, which in turn includes a first surface on which is formed a MEMS device. The package also includes a polymer ring with an inner wall extending between first and second oppositely facing surfaces. The first surface of the polymer ring is bonded to the first surface of the first substrate to define a first cavity in which the MEMS device is contained. A molded compound body having a second cavity that is concentric with the first cavity, enables fluid communication between the MEMS device and an environment external to the package.

摘要： The present invention generally relates to a MEMS device having a plurality of cantilevers that are coupled together in an anchor region and/or by legs that are coupled in a center area of the cantilever. The legs ensure that each cantilever can move/release from above the RF electrode at the same voltage. The anchor region coupling matches the mechanical stiffness in all sections of the cantilever so that all of the cantilevers move together.

摘要： A MEMS device includes a semiconductor support body having a first cavity, a membrane including a peripheral portion, fixed to the support body, and a suspended portion. A first deformable structure is at a distance from a central part of the suspended portion of the membrane and a second deformable structure is laterally offset relative to the first deformable structure towards the peripheral portion of the membrane. A projecting region is fixed under the membrane. The second deformable structure is deformable so as to translate the central part of the suspended portion of the membrane along a first direction, and the first deformable structure is deformable so as to translate the central part of the suspended portion of the membrane along a second direction.
