    Abstract: A method of fabricating a device using a multi-layered wafer that has an embedded etch mask adapted to map a desired device structure onto an adjacent (poly)silicon layer. Due to the presence of the embedded mask, it becomes possible to delay the etching that forms the mapped structure in the (poly)silicon layer until a relatively late fabrication stage. As a result, flatness of the (poly)silicon layer is preserved for the deposition of any necessary over-layers, which substantially obviates the need for filling the voids created by the structure formation with silicon oxide.

    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: A MEMS device which utilizes a capacitive sensor or actuator is enhancement by initially fabricating the capacitive assembly which comprises the sensor or actuator as two sets of interdigitated fingers in a noninterdigitated configuration. One of the two sets of fingers is coupled to a movable stage. The stage is moved from an initial position to a post-release position in which the two sets of interdigitated fingers are interdigitated with each other. The stage is carried by two pairs flexures which maintain the stability of motion of the stage and when in the post-release position provide stiffness which prevents deflection of the set of fingers coupled to the stage. The stage and hence the assembled sets of fingers are then locked into the post-release position.
