    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: 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: A micromechanical structural element, having a very stable diaphragm, implemented in a pure front process and in a layer construction on a substrate. The layer construction includes at least one sacrificial layer and one diaphragm layer above the sacrificial layer, which is structured for laying bare the diaphragm and generating stabilizing elements on the diaphragm, at least one recess being generated for a stabilizing element of the diaphragm. The structure generated in the sacrificial layer is then at least superficially closed with at least one material layer being deposited above the structured sacrificial layer, this material layer forming at least a part of the diaphragm layer and being structured to generate at least one etch hole for etching the sacrificial layer, which is removed from the region under the etch hole, the diaphragm and the at least one stabilizing element being laid bare, a cavity being created under the diaphragm.

    Abstract: A suspended semiconductor film is anchored to a substrate at at least two opposed anchor positions, and film segments are deposited on the semiconductor film adjacent to one or more of the anchor positions to apply either tensile or compressive stress to the semiconductor film between the film segments. A crystalline silicon film may be anchored to the substrate and have tensile stress applied thereto to reduce the lattice mismatch between the silicon and a silicon-germanium layer deposited onto the silicon film. By controlling the level of stress in the silicon film, the size, density and distribution of quantum dots formed in a high germanium content silicon-germanium film deposited on the silicon film can be controlled.

Alternatively, the method includes forming a multilayer MEMS structure by photomasking processes to form a first metal layer, a second layer including a dielectric layer and a second metal layer, and a third metal layer. The core layer and the encapsulating layers are made of materials with complementary electrical, mechanical and/or magnetic properties.
