    Abstract: A junctionless Nano-Electro-Mechanical (NEM) resonator, comprising a highly doped conductive channel connecting a drain region and a source region; the conduction channel region is movable and the overall structure is fixed at least at these two ends placed on acting the source and drain regions, respectively; at least one fixed gate electrode arranged to control a depletion charge in the highly doped conductive channel thereby modulating dimensions of a cross-section of the highly doped conductive channel. A dimension of the cross-section in the direction of an electrical field that is oriented from the fixed gate electrode to the highly doped conductive channel, is designed in such a way that it can be reduced under the effect of the depletion charge such that a full depletion in the highly doped conductive channel is achievable with the control of the fixed gate electrode.

    Abstract: A MEMS apparatus comprising composite vibrating unit and the manufacturing method thereof are disclosed. The vibrating unit includes a stiffness element on which a first material is disposed. A second material being a conductive material is disposed on the first material and is extended to the stiffness element to remove electric charge on first material. When a temperature is changed, a variation direction of a Young's modulus of the first material is opposite to a variation direction of a Young's modulus of the stiffness element. The unique attributes above allow vibrating unit of the MEMS apparatus such as resonator and gyroscope to have stable resonance frequency against the change of temperature.

    Abstract: Integrated Microelectromechanical System (“MEMS”) devices and methods for making the same. The MEMS devices comprise a substrate (200) and a MEMS filter device (100) mechanically suspended above a major surface of the substrate. A first gas gap (202) exists between the major surface of the substrate and the MEMS filter device. An isolation platform (500) is provided to absorb vibrations from an external environment prior to reaching the MEMS filter device. In this regard, the isolation platform comprises: a frame structure (510) framing a periphery of the MEMS filter device; and at least one resilient component (512-518) coupled between the frame structure and the MEMS filter device. The frame structure is mechanically connected to the substrate. Electronic circuitry is connected to the MEMS filter device via a resilient interconnection (204, 206) that is movable in at least one direction of the vibrations.
