Abstract: The present invention is generally directed to a method and assembly for elevating and supporting a microstructure of a MEM system generally by engaging a positioning system of the MEM system with a first elevator lifter. The MEM system generally includes a first microstructure (such as a mirror) disposed in vertically spaced relation to a substrate. The positioning system generally includes an actuator assembly movably interconnected with the substrate, an elevator pivotally interconnected with the substrate and further interconnected with the microstructure, and a tether interconnecting the actuator assembly and the elevator. The first elevator lifter is provided to engage the elevator to lift/elevate the microstructure away from the substrate generally after fabrication of the MEM system and prior to utilizing the microstructure in operation of the MEM system.

Abstract: A meso-scale MEMS device having a movable member (51) is formed using standard printed wiring board and high density interconnect technologies and practices. In one embodiment, sacrificial material disposed about the movable member (51) is removed through openings (101, 102) as formed through a cover (91) to form a cavity (121) that retains and limits the freedom of movement of the movable member (51). The movable member can support a reflective surface (224) to thereby provide a mechanism that will support a projection display and/or image scanner (such as a bar code scanner).

Abstract: An electrostatic bimorph actuator includes a cantilevered flexible bimorph arm that is secured and insulated at one end to a planar substrate. In an electrostatically activated state the bimorph arm is generally parallel to the planar substrate. In a relaxed state, residual stress in the bimorph arm causes its free end to extend out-of-plane from the planar substrate. The actuator includes a substrate electrode that is secured to and insulated from the substrate and positioned under and in alignment with the bimorph arm. An electrical potential difference applied between the bimorph arm and the substrate electrode imparts electrostatic attraction between the bimorph arm and the substrate electrode to activate the actuator. As an exemplary application in which such actuators could be used, a microelectrical mechanical optical display system is described.

Abstract: An array of nanometric dimensions consisting of two or more arms, positioned side by side, wherein the arms are of such nanometric dimensions that the beams can be moved or deformed towards or away from one another by means of a low voltage applied between the beams, whereby to produce a desired optical, electronic or mechanical effect. At nanometer scale dimensions structures previously treated as rigid become flexible, and this flexibility can be engineered since it is a direct consequence of material and dimensions. Since the electrostatic force between the two arms is inversely proportional to the square of the distance, a very considerable force will be developed with a low voltage of the order of 1-5 volts, which is sufficient to deflect the elements towards or away from one another. As preferred, the bulk of the element may be comprises an insulating material, and an upper conductive layer is applied on the upper surface, where the element is formed by a nanolithography method such as nanoimprint lithography (NIL). Alternatively the elements may be formed completely of conductive material, where the elements are formed by a CMOS metalization process.

Abstract: An optical switch device includes a rolling shutter or membrane attached at one of its edges to a substrate near an optical port in the substrate. The rolling shutter can assume one of two states. In a first closed state, the membrane is uncoiled onto the substrate over the port such that light directed at the port impinges on the shutter. In a second open state, the membrane is rolled up away from the port such that light directed at the port impinges on the port. In one embodiment, a mirror is formed on the membrane such that when the membrane is in the closed state over the substrate, light directed at the port is reflected by the mirror. In one configuration, the optical port includes a hole or aperture such light passed through the port without interference. The device can include a latch electrode the far end of the membrane such that when it is rolled out, it can be held in position by a latching voltage applied across the latch electrode and the substrate. Slits can be formed in the membrane to keep the mirror flat by relieving strain in the membrane and to allow gases in proximity to the device to pass through the membrane as it is activated. The shutter can include dimples to minimize the area of contact between the membrane and the substrate to reduce the probability of the two sticking together. The attachment edge of the membrane can be made shorter than its width to reduce distortions in the membrane to keep the mirror flat. A raised annular rim can be provided around the port such that when the shutter is held down over the port it is pulled taut and flat over the rim. This feature is also used to maintain flatness in the mirror. The switch device can be used as part of an array of optical switches.
