    Abstract: Multi-level structures are formed in a semiconductor substrate by first forming a pattern of lines or structures of different widths. Width information on the pattern is decoded by processing steps into level information to form a MEMS structure. The pattern is etched to form structures having a first floor. The structures are oxidized until structures of thinner width are substantially fully oxidized. A portion of the oxide is then etched to expose the first floor. The first floor is then etched to form a second floor. The oxide is then optionally removed, leaving a multi-level structure. In one embodiment, high aspect ratio comb actuators are formed using the multi-level structure process.

    Abstract: A hybrid electro-static actuator for rotating a two-dimensional micro-electro-mechanical micro-mirror device about two perpendicular axes includes a vertical comb drive for rotating the micro-mirror about a tilt axis, and a parallel plate drive for rotating the micro-mirror about a roll axis. The rotor comb fingers of the comb drive extend from a sub-frame of the micro-mirror, which is only rotatable about the tilt axis, while one of the parallel plate electrodes is mounted on the underside of a main platform, which generally surrounds the sub-frame. The vertical comb drive rotates both the sub-frame and the main platform about the tilt axis, while the parallel plate drive only rotates the main platform about the roll axis.

    Abstract: A micro-electro-mechanical system (MEMS) device includes an oscillating body and a beam connected to the oscillating body. The beam has a proximal end connected to the oscillating body, a distal end spaced from the oscillating body, and rotational comb teeth extending from the beam. Springs couple the beam to stationary pads to allow the oscillating body to rotate about a rotational axis. The springs are arranged along the rotation axis so at least one spring is located between another spring and the oscillating body. Stationary comb teeth extend from a stationary pad to be interdigitated with the rotational comb teeth extending from the beam. A voltage difference is applied between the stationary and rotational comb teeth to rotate the oscillating body about the rotation axis. A bottom layer includes mounting pads for supporting the stationary pads. An electrode is formed on a surface of the bottom layer. A voltage or ground is applied to the electrode to assert a physical influence on the rotation of the oscillating body.

    Abstract: A micro-electro-mechanical component comprising a movable element with comb electrodes, and two stationary elements with comb electrodes aligned and stacked on each other but electrically insulated by a layer of insulation material. The movable element is supported by multiple torsional hinges and suspended over a cavity such that the element can oscillate about an axis defined by the hinges. The comb electrodes of the movable element are interdigitated with the comb electrodes of one stationary element in the same plane to form an in-plane comb actuator. The comb electrodes of the movable element are also interdigitated in an elevated plane with the comb electrodes of another stationary element to form a vertical comb actuator. As a result, the micro-electro-mechanical component is both an in-plane actuator and a vertical comb actuator, or a multiple-plane actuator. Methods of fabricating such actuator are also described.

    Abstract: The invention relates to a method of fabrication of staggered vertical comb drive actuators with relaxed lateral alignment tolerances. A device layer of a wafer is first etched from a front side using a self-aligned two-layer mask to define interdigited fingers of both moving and stationary combs. A second etch step is used for vertically thinning one of the two sets of fingers by selectively removing their top portions. The front side of the wafer is then bonded to a carrier wafer. The wafer is then selectively etched from the back side of the device layer so as to remove lower portions of the second set of fingers, thereby forming interdigited moving and stationary combs having vertically offset fingers.

    Abstract: A process for fabricating a micro-electro-mechanical system (MEMS) composed of fixed components fixedly supported on a lower substrate and movable components movably supported on the lower substrate. The process utilizes an upper substrate separate from the lower substrate. The upper substrate is selectively etched in its top layer to form therein a plurality of posts which project commonly from a bottom layer of the upper substrate. The posts include the fixed components to be fixed to the lower substrate and the movable components which are resiliently supported only to one or more of the fixed components to be movable relative to the fixed components. The lower substrate is formed in its top surface with at least one recess. The upper substrate is then bonded to the top of the lower substrate upside down in such a manner as to place the fixed components directly on the lower substrate and to place the movable components upwardly of the recess. Finally, the bottom layer of the upper substrate is removed to release the movable components from the bottom layer for floating the movable components above the recess and allowing them to move relative to the lower substrate, while keeping the fixed components fixed to the top of the lower substrate.
