    摘要: A method for fabricating an integrated MEMS device and the resulting structure therefore. A control process monitor comprising a MEMS membrane cover can be provided within an integrated CMOS-MEMS package to monitor package leaking or outgassing. The MEMS membrane cover can separate an upper cavity region subject to leaking from a lower cavity subject to outgassing. Differential changes in pressure between these cavities can be detecting by monitoring the deflection of the membrane cover via a plurality of displacement sensors. An integrated MEMS device can be fabricated with a first and second MEMS device configured with a first and second MEMS cavity, respectively. The separate cavities can be formed via etching a capping structure to configure each cavity with a separate cavity volume. By utilizing an outgassing characteristic of a CMOS layer within the integrated MEMS device, the first and second MEMS cavities can be configured with different cavity pressures.

    摘要: A method and structure for fabricating an inertial sensing device using tilt conversion to sense a force in the out-of-plane direction. The method can include forming anchor structure(s) coupled to portions of a surface region of a substrate member. Also, the method can include forming flexible anchor members coupled to portions of the anchor structures and frame structures, which can be formed overlying the substrate. The method can also include forming flexible frame members coupled to portions of the frame structures and movable structures, which can also be formed overlying the substrate. Forming the movable structures can include forming peripheral and central movable structures, which can be coupled to flexible structure members. Peripheral movable structures having flexible tilting members can convert a pure tilting out-of-plane motion to a pure translational out-of-plane motion. The forming of these elements can include performing an etching process on a single silicon material.

    摘要: An integrated MEMS System. CMOS and MEMS devices can be provided in order to form an integrated CMOS-MEMS system. The system can include a silicon substrate layer, a CMOS layer, MEMS and CMOS devices, and a wafer level packaging (WLP) layer. The CMOS layer can form an interface region, one which any number of CMOS MEMS devices can be configured. The integrated MEMS devices can include, but not exclusively, an combination of the following types of sensors: magnetic, pressure, humidity, temperature, chemical, biological, or inertial. Furthermore, the overlying WLP layer can be configured to hermetically seal any number of these integrated devices. The present technique provides an easy to use process that relies upon conventional process technology without substantial modifications to conventional equipment and process and reduces off-chip connections, which make the mass production of smaller and thinner units possible.
