    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.

    Abstract: Described herein is the use of a diffusion barrier layer between metallic layers in MEMS devices. The diffusion barrier layer prevents mixing of the two metals, which can alter desired physical characteristics and complicate processing. In one example, the diffusion barrier layer may be used as part of a movable reflective structure in interferometric modulators.

    Abstract: A microelectromechanical (MEM) apparatus is disclosed which includes one or more tensile-stressed actuators that are coupled through flexures to a stage on a substrate. The tensile-stressed actuators, which can be formed from tensile-stressed tungsten or silicon nitride, initially raise the stage above the substrate without any applied electrical voltage, and can then be used to control the height or tilt angle of the stage. An electrostatic actuator can also be used in combination with each tensile-stressed actuator. The MEM apparatus has applications for forming piston micromirrors or tiltable micromirrors and independently addressable arrays of such devices.

    Abstract: A thin film made of an amorphous material having a supercooled liquid phase region is formed on a substrate. Then, the thin film is heated to a temperature within the supercooled liquid phase region and is deformed by its weight, mechanical external force, electrostatic external force or the like, thereby to form a thin film-structure. Thereafter, the thin film-structure is cooled down to room temperature, which results in the prevention of the thin film's deformation.

    Abstract: A method for manufacturing a semiconductor physical quantity sensor including a support substrate, a movable electrode, a fixed electrode is provided. The method includes the steps of: preparing a multi-layered substrate; forming a compression stress layer on a part of a surface of the semiconductor layer; forming a trench in the semiconductor layer; and releasing the movable electrode from the substrate by removing the insulation film. In the step of releasing, the part of the semiconductor layer, on which the compression stress layer is disposed, is cambered by the compression stress toward a direction apart from the substrate.
