    Abstract: This invention disclosed a method to strengthen structure and enhance sensitivity for CMOS-MEMS micro-machined devices which include micro-motion sensor, micro-actuator and RF switch. The steps of the said method contain defining deposited region by metal and passivation layer, forming a cavity for depositing metal structure by lithography process, depositing metal structure on the top metal layer of micromachined structure by Electroless plating, polishing process and etching process. The method aims at strengthening structures and minimizing CMOS-MEMS device size. Furthermore, this method can also be applied to inertia sensors such as accelerometer or gyroscope, which can enhance sensitivity and capacitive value, and deal with curl issues for suspended CMOS-MEMS devices.

    Abstract: Embodiments of MEMS devices include a movable layer supported by overlying support structures, and may also include underlying support structures. In one embodiment, the residual stresses within the overlying support structures and the movable layer are substantially equal. In another embodiment, the residual stresses within the overlying support structures and the underlying support structures are substantially equal. In certain embodiments, substantially equal residual stresses are be obtained through the use of layers made from the same materials having the same thicknesses. In further embodiments, substantially equal residual stresses are obtained through the use of support structures and/or movable layers which are mirror images of one another.

    Abstract: Methods of forming ceramic components are disclosed. One method calls for chemical vapor depositing a ceramic material over a substrate having first and second opposite surfaces to define a coated structure, the ceramic material forming a layer overlying both the first and second opposite surfaces. The layer and the substrate have a difference in thermal expansion coefficients of at least 0.5 ppm/K. The substrate is removed, leaving behind the layer. Ceramic components and coated structures are also disclosed.

    Abstract: Certain MEMS devices include layers patterned to have tapered edges. One method for forming layers having tapered edges includes the use of an etch leading layer. Another method for forming layers having tapered edges includes the deposition of a layer in which the upper portion is etchable at a faster rate than the lower portion. Another method for forming layers having tapered edges includes the use of multiple iterative etches. Another method for forming layers having tapered edges includes the use of a liftoff mask layer having an aperture including a negative angle, such that a layer can be deposited over the liftoff mask layer and the mask layer removed, leaving a structure having tapered edges.

    Abstract: Methods and apparatus are provided for controlling a depth of a cavity between two layers of a light modulating device. A method of making a light modulating device includes providing a substrate, forming a sacrificial layer over at least a portion of the substrate, forming a reflective layer over at least a portion of the sacrificial layer, and forming one or more flexure controllers over the substrate, the flexure controllers configured so as to operably support the reflective layer and to form cavities, upon removal of the sacrificial layer, of a depth measurably different than the thickness of the sacrificial layer, wherein the depth is measured perpendicular to the substrate.

    Abstract: A method for controlling residual stress in a structure in a MEMS device and a structure thereof includes selecting a total thickness and an overall equivalent stress for the structure. A thickness for each of at least one set of alternating first and second layers is determined to control an internal stress with respect to a neutral axis for each of the at least alternating first and second layers and to form the structure based on the selected total thickness and the selected overall equivalent stress. Each of the at least alternating first and second layers is deposited to the determined thickness for each of the at least alternating first and second layers to form the structure.

    Abstract: A method of fabricating a silicon-based microstructure is disclosed, which involves depositing electrically conductive amorphous silicon doped with first and second dopants to produce a structure having a residual mechanical stress of less than +/=100 Mpa. The dopants can either be deposited in successive layers to produce a laminated structure with a residual mechanical stress of less than +/=100Mpa or simultaneously to produce a laminated structure having a mechanical stress of less than +/=100Mpa.
