    Abstract: A micrometer sized, single-stage, vertical thermal actuator with controlled bending capable of repeatable and rapid movement of a micrometer-sized optical device off the surface of a substrate. The vertical thermal actuator is constructed on a surface of a substrate. At least one hot arm has a first end anchored to the surface and a free end located above the surface. A cold arm has a first end anchored to the surface and a free end. The cold arm is located above the hot arm relative to the surface. The cold arm is adapted to provide controlled bending near the first end thereof. A member mechanically and electrically couples the free ends of the hot and cold arms such that the actuator bends generally at the flexure so that the member moves away from the substrate when current is applied to at least the hot arm.

    Abstract: A monolithically integrated, electromechanical microwave switch, capable of handling signals from DC to millimeter-wave frequencies, and an integrated electromechanical tunable capacitor are described. Both electromechanical devices include movable beams actuated either by thermo-mechanical or by electrostatic forces. The devices are fabricated directly on finished silicon-based integrated circuit wafers, such as CMOS, BiCMOS or bipolar wafers. The movable beams are formed by selectively removing the supporting silicon underneath the thin films available in a silicon-based integrated circuit technology, which incorporates at least one polysilicon layer and two metallization layers. A cavity and a thick, low-loss metallization are used to form an electrode above the movable beam. A thick mechanical support layer is formed on regions where the cavity is located, or substrate is bulk-micro-machined, i.e., etched.

    Abstract: Improved microelectromechanical structures include spaced-apart supports on a microelectronic substrate and a beam that extends between the spaced-apart supports and that expands upon application of heat thereto to thereby cause displacement of the beam between the spaced-apart supports. A heater, located on the beam, applies heat to the beam and displaces with the beam as the beam displaces. Therefore, heat can be directly applied to the arched beam, thereby reducing thermal loss between the heater and the arched beam. Furthermore, an air gap between the heater and arched beam may not need to be heated, thereby allowing improved transient thermal response. Moreover, displacing the heater as the arched beam displaces may further reduce thermal loss and transient thermal response by reducing the separation between the heater and the arched beam as the arched beam displaces.

    Abstract: A microelectromechanical (MEMS) device is provided that includes a microelectronic substrate and a thermally actuated microactuator and associated components disposed on the substrate and formed as a unitary structure from a single crystalline material, wherein the associated components arc actuated by the microactuator upon thermal actuation thereof. For example, the MEMS device may be a valve. As such, the valve may include at least one valve plate that is controllably brought into engagement with at least one valve opening in the microelectronic substrate by selective actuation of the microactuator. While the MEMS device can include various microactuators, the microactuator advantageously includes a pair of spaced apart supports disposed on the substrate and at least one arched beam extending therebetween. By heating the at least one arched beam of the microactuator, the arched beams will further arch such that the microactuator moves between a closed position in which the valve plate sealingly engages the valve opening and an open position in which the valve plate is at least partly disengaged from and does not seal the valve opening. The microactuator may further include metallization traces on distal portions of the arched beams to constrain the thermally actuated regions of arched beams to medial portions thereof. The valve may also include a latch for maintaining the valve plate in a desired position without requiring continuous energy input to the microactuator. An advantageous method for fabricating a MEMS valve having unitary structure single crystalline components is also provided.
