    Abstract: Nanocrystalline diamond coatings exhibit stress in nano/micro-electro mechanical systems (MEMS). Doped nanocrystalline diamond coatings exhibit increased stress. A carbide forming metal coating reduces the in-plane stress. In addition, without any metal coating, simply growing UNCD or NCO with thickness in the range of 3-4 micron also reduces inplane stress significantly. Such coatings can be used in MEMS applications.

    Abstract: PROBLEM TO BE SOLVED: To improve the cost and convenience of a sensor element for spectroscopic or optical measurement and a method for manufacturing the same. SOLUTION: A sensor element for spectroscopic/optical measurement includes: a sensor chip 2 having a measuring device 3 for sensing a beam 10; a cap chip 6 fixed to a sensor chip via a vacuum-sealing connector 5; a free space 7 formed between the cap chip and the measuring device and sealed with the connector 5; and a Fresnel zone structure 12 that focuses the incident beam 10 on the measuring device. A Fresnel lens is not realized as a three-dimensional structure on an upper surface of the chip but realized inside of the cap chip. That is, the Fresnel zone structure is formed inside of the cap chip. Therefore, the present invention makes it possible to realize a Fresnel lens, integrated on a cap wafer, which has a flat surface. It is possible to avoid a Fresnel lens taking the form of a three-dimensional structure and to realize the Fresnel lens in a cap wafer or a cap chip. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: The present disclosure discloses a bipolar transistor type MEMS pressure sensor and a preparation method thereof. The bipolar transistor type MEMS pressure sensor includes a thin film, a cantilever beam and a bipolar transistor. The bipolar transistor includes a base region, a collector region and an emitter region. The base region is configured to sense deformation of the thin film through a change in resistance value. For the bipolar transistor type MEMS pressure sensor of the disclosure, sensitivity of the sensor can be effectively improved without changing the performance indicators such as the measurement range and nonlinearity. Meanwhile, the bipolar transistor is used as a pressure-sensitive element, so that temperature drift of the sensor can be effectively inhibited.
