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.
