    Abstract: An electrostatic micromotor employs a side drive design. The stator operates in a plane above a substract and a moveable member lies and moves in the plane of the stator. An electrostatic field of operational strength is generated and sustained without breakdown in the plane between the stator and edges of the moveable member. Three fabrication processes enable formation of a moveable member in the plane of operation of the stator and spaced apart from the stator by a micron amount. One fabrication process deposits and patterns a structural layer to form the stator and moveable member over a sacrificial layer. A second fabrication process etches channels in a first structural layer to outline a stator, moveable member, and if desired, a bearing. A substrate is connected to the side of the structural layer through which the channels are etched and the opposite side is ground down to the ends of the channels to form salient stator, rotor and, if desired, bearing structures. The third fabrication process grows a sacrificial layer by local oxidation in an etched cavity of the substrate. A structural layer is then deposited and patterned over the substrate and sacrificial layer to form the stator and moveable member in a common plane. A harmonic side drive micromotor is also provided by the fabrication processes.

    Abstract: Disclosed are MEMS accelerometers and methods for fabricating same. An exemplary accelerometer comprises a substrate, and a proof mass that is a portion of the substrate and which is separated from the substrate surrounding it by a gap. An electrically-conductive anchor is coupled to the proof mass, and a plurality of electrically-conductive suspension anus that are separated from the proof mass extend from the anchor and are coupled to the substrate surrounding the proof mass. A plurality of sense and actuation electrodes are separated from the proof mass by gaps and are coupled to processing electronics. Capacitive sensing is used to derive electrical signals caused by forces exerted on the proof mass, and the electrical signals are processed by the processing electronics to produce x-, y- and z-direction acceleration data. Electrostatic actuation is used to induce movements of the mass for force balance operation, or self-test and self-calibration. The fabrication methods use deep reactive ion etch bulk micromachining and surface micromachining to form the proof mass, suspension arms and electrodes. The anchor, suspension arms and electrodes are made in the same process steps from the same electrically conductive material, which is different from the substrate material.

    Abstract: A polysilicon micromotor, of either inner rotor or outer rotor design, is fabricated with a process that uses as few as three mask steps. In an outer rotor (wobble) micromotor, a free-rotating insulating flange bearing mechanically couples the inner periphery of the rotor to the stator, permitting the outer periphery of the rotor to be directly coupled to other mechanisms. The dielectric constant of the flange bearing increases motive torque of the motor as contrasted with air-gap designs. This and other factors results in motive torque, in the illustrated embodiment, more than 100 times larger than in previous designs. Among its other benefits, the disclosed fabrication process results in in-place formation of all motor elements, and enables precise definition of the rotor/stator gap.
