Actuator device
An actuator device includes: a support portion; a movable portion; a first connection portion connecting the movable portion to the support portion on a first axis so that the movable portion is swingable around the first axis; and a first wiring provided on the first connection portion. The first wiring includes a first main body formed of a metal material having a Vickers hardness of 50 HV or more. The first main body includes a first surface facing the first connection portion and a second surface other than the first surface. The second surface has a shape in which a curvature is continuous over the entire second surface in a cross-section perpendicular to an extension direction of the first wiring.
Micromechanical Component and Method for Adjusting an Adjustable Part Simultaneously about Two Axes of Rotation Inclined in Relation to One Another
A micromechanical component includes an adjustable part, a mounting, at least one bending actuator, and a permanent magnet. The part is positioned on the mounting so as to be adjustable relative to the mounting about a first rotation axis and about a second rotation axis inclined relative to the first axis. The actuator includes at least one movable subregion. Movement of the subregion results in a restoring force that moves the part about the first axis. The part is connected indirectly to the magnet to be adjustable about the second axis of rotation via a magnetic field built up by the magnet together with a yoke device of the component or an external yoke. A micromirror device includes the micromechanical component. A method for adjusting the part includes adjusting the part simultaneously about the first and the second axes.
Method of processing a wafer for manufacturing an oscillating structure such as a micro-mirror
To manufacture an oscillating structure, a wafer is processed by: forming torsional elastic elements; forming a mobile element connected to the torsional elastic elements; processing the first side of the wafer to form a mechanical reinforcement structure; and processing the second side of said wafer by steps of chemical etching, deposition of metal material, and/or deposition of piezoelectric material. Processing of the first side of the wafer is carried out prior to processing of the second side of the wafer so as not to damage possible sensitive structures formed on the first side of the wafer.
Detachable MEMS package top cover
A MEMS chip package is provided with a removable cover to allow non-destructive testing. The MEMS package has a container (with walls and a bottom) and a cover. The cover has a glass pane, and is secured to the MEMS package with an elastomeric gasket mounted between the walls of the MEMS package and the cover. A number of attachment mechanisms secure the cover to the MEMS package.
MEMS CHIP, MANUFACTURING METHOD THEREOF, MEMS DEVICE, AND ELECTRONIC DEVICE
An MEMS chip includes a substrate, a movable assembly, a fastening assembly, and a drive assembly. The fastening assembly is located between the substrate and the movable assembly. The movable assembly includes a fastening portion, a movable portion, and a first support beam. The first support beam is connected to the movable portion and the fastening portion. A first avoidance slot is disposed on a face that is of the movable portion and that faces the fastening assembly. The fastening assembly is grounded. A boss and a first position limiting pole are disposed on a face that is of the fastening assembly and that faces the movable assembly. The boss is connected to the fastening portion and configured to support the fastening portion. The first position limiting pole corresponds to the first avoidance slot. The drive assembly is connected to the movable portion to drive the movable portion to move.
Wavefront reversal device using a MEMS spatial phase modulator integrated with a retroreflector array
Wavefront reversal device using a MEMS spatial phase modulator integrated with a retroreflector array. A cat's eye retro reflector array is integrated with a phase only MEMS spatial light modulator (SLM) so that each cat's eye retro-reflector in the array is integrated into each pixel of the MEMS SLM. The composite MEMS device provides continuous analog phase modulation and retro-reflection for each pixel. By integrating a cat's retro-reflector onto each pixel, the combination provides both phase-shifting control and tilt compensation of piecewise optical beams, on a pixel-by-pixel basis. The resultant device emulates a deformable mirror with an integrated cat's eye retro array, the combination of which is equivalent to a true wave front reversal device.
Optical electronics device
An optical electronics device includes first, second and third wafers. The first wafer has a semiconductor substrate with a dielectric layer on a side of the semiconductor substrate. The second wafer has a transparent substrate with an anti-reflective coating on a side of the transparent substrate.

The first and second wafers include a cavity extending from the dielectric layer through the semiconductor substrate and through the silicon dioxide layer to the anti-reflective coating. The third wafer includes micromechanical elements. The third wafer is bonded to the dielectric layer, and the micromechanical elements are contained within the cavity.
