    摘要: A micro-electro-mechanical system (MEMS) package structure and a method for fabricating the MEMS package structure. The MEMS package structure includes a MEMS die (200) and a device wafer (100). A control unit and an interconnection structure (300) are formed in the device wafer (100), and a first contact pad (410) and an input-output connecting member (420) are formed on a first bonding surface (100a) of the device wafer (100). The MEMS die (200) is coupled to the first bonding surface (100a) through a bonding layer (500). The MEMS die (200) includes a closed micro-cavity (220) and a second contact pad (220). The first contact pad (410) is electrically connected to a corresponding second contact pad (220). An opening (510) that exposes the input-output connecting member (420) is formed in the bonding layer (500). The MEMS package structure allows electrical interconnection between the MEMS die (200) and the device wafer (100) with a reduced package size, compared to those produced by existing integration techniques. In addition, function integration ability of the package structure is improved by integrating a plurality of MEMS dies of the same or different structures and functions on the same device wafer.

    摘要: A MEMS device is a MEMS device having a MEMS vibrator which includes a plurality of MEMS constituent elements laminated and formed above a first foundation portion which is laminated above a main surface of a wafer substrate, and the MEMS constituent elements are laminated above a first oxide film and a nitride film so as to cover an opening which is formed in the nitride film and exposes a second foundation portion above which the nitride film is laminated.
