    Abstract: This disclosure provides systems, methods and apparatus for controlling a mechanical layer. In one aspect, an electromechanical systems device includes a substrate and a mechanical layer positioned over the substrate to define a gap. The mechanical layer is movable in the gap between an actuated position and a relaxed position, and includes a mirror layer, a cap layer, and a dielectric layer disposed between the mirror layer and the cap layer. The mechanical layer is configured to have a curvature in a direction away from the substrate when the mechanical layer is in the relaxed position. In some implementations, the mechanical layer can be formed to have a positive stress gradient directed toward the substrate that can direct the curvature of the mechanical layer upward when the sacrificial layer is removed.

    Abstract: MEMS devices (40) using etched cavities (42) are desirably formed using multiple etching steps. Preliminary cavities (20) formed by locally anisotropic etching to nearly the final depth have irregular (46) sidewalls (44) and steep and/or inconsistent sidewall (44) to bottom (54) intersection angles (48). This leads to less than desired cavity diaphragm (26) burst strengths. Final cavities (42) with smooth sidewalls (50), smaller and consistent sidewall (50) to bottom (54) intersection angles (58), and having more than doubled cavity diaphragm (26) burst strengths are obtained by treating the preliminary cavities (20) with TMAH etchant, preferably relatively dilute TMAH etchant. In a preferred embodiment, a cleaning step is performed between the etching step and the TMAH treatment step to remove any anisotropic etching by-products present on the preliminary cavities' (20) initial sidewalls (44). The multi-step cavity etching procedure is especially useful for forming robust MEMS pressure sensors, but is applicable to any type of MEMS device.

    Abstract: Electronic devices are disclosed that may be used for infrared radiation detection. An example electronic device includes a substrate, a transistor included in the substrate and a silicon-germanium (Si—Ge) structural layer coupled with the transistor. The structural layer has a stress in a predetermined range, where the predetermined range for the stress is selected prior to deposition of the structural layer. Also, the structural layer is deposited on the substrate subsequent to formation of the transistor such that deposition of the structural layer does not substantially adversely affect the operation of the transistor.
