Abstract:
The disclosure generally relates to method and apparatus for forming three-dimensional MEMS. More specifically, the disclosure relates to a method of controlling out-of-plane buckling in microstructural devices so as to create micro-structures with out-of-plane dimensions which are 1×, 5×, 10×, 100× or 500× the film's thickness or above the surface of the wafer. An exemplary device formed according to the disclosed principles, includes a three dimensional accelerometer having microbridges extending both above and below the wafer surface.
Abstract:
Microbolometers with regionally thinned microbridges are produced by depositing a thin film (0.6 μm) of silicon nitride on a silicon substrate, forming microbridges on the substrate, etching the thin film to define windows in a pixel area, thinning the windows, releasing the silicon nitride, depositing a conductive YBaCuO film on the bridges, depositing a conductive film (Au) on the YBaCuO film, and removing selected areas of the YBaCuO and conductive films.
Abstract:
A method for fabricating an electronic device includes the steps of: preparing a cavity defining sacrificial layer, at least the upper surface of which is covered with an etch stop layer; forming at least one first opening in the etch stop layer, thereby partially exposing the surface of the cavity defining sacrificial layer; etching the cavity defining sacrificial layer through the first opening, thereby defining a provisional cavity under the etch stop layer and a supporting portion that supports the etch stop layer thereon; and etching away a portion of the etch stop layer, thereby defining at least one second opening that reaches the provisional cavity through the etch stop layer and expanding the provisional cavity into a final cavity.

PROBLEM TO BE SOLVED: To provide a piezoelectric device causing no deterioration of piezoelectric characteristics under high temperatures, and having excellent heat resistance, to provide a manufacturing method of the same, and to provide an electronic apparatus. SOLUTION: This piezoelectric device (angular velocity sensor element 31) is equipped with a piezoelectric film 33 disposed between a first electrode film 34a and a second electrode film 34b. The piezoelectric film 33 is represented by chemical formula Pb 1+X (Zr Y Ti 1-Y )O 3+X (0≤X≤0.3, 0≤Y≤0.55), and the peak intensity of a pyrochlore phase which is measured by an X-ray diffraction method is not more than 10% in comparison with the sum of peak intensity in respective plane orientations of (100), (001), (110), (101) and (111) of perovskite phases. The film thickness of the piezoelectric film 33 is 400-1,000 nm. COPYRIGHT: (C)2010,JPO&INPIT
