MEMS开关辐照实验研究 总被引:2,自引:0,他引:2
进行了MEMS开关的辐照试验,并对结果进行了分析。所述的MEMS开关采用单晶硅悬臂梁结构实现金属电极接触,工作电压小于50V,最大工作频率大于10kHz。进行了中子辐照和γ辐照实验,其中中子注量为2.73×1013cm-2,γ总剂量为50krad(Si)。并通过对MEMS开关辐照前后性能的测试,获得了辐照对MEMS开关性能影响的实验数据。结果表明,在辐照剂量大于10krad(Si)时MEMS开关性能有明显变化。借鉴国外的相关研究成果,对MEMS器件的辐照失效机理进行了初步分析。 相似文献

The design, fabrication and test of a novel MEMS inclinometer were described. This inclinometer was based on the piezoresistive detection method, and was fabricated by SOI process. The micro-structure of the inclinometer was a four vertical cantilever beams, a center mass with a rigid cylinder fixed on it. The piezoresistors fabricated on the beams were used to detect the deformation of the cantilevers caused by the gravity. A test system was designed in this paper, from the test results we found that this inclinometer had a sensitivity of 0.025 mV/°, and the test results and the theoretical results are in well agreement, the standard deviation is 0.43874. 相似文献

A self-assembly method is introduced for the assembly of micro-parts onto Si substrates based on analogy of the Langmuir−Blodgett technique. To perform the assembly, Si substrates are prepared with solder-coated binding sites. The micro-parts are suspended in the butyl acetate-water mixture, and after gentle agitation, the micro-parts form a uniform and well-ordered 2-D aggregate at the butyl acetate-water interface. The micro-parts are attached onto the substrate by passing the substrate vertically through the aggregate of micro-parts. Due to the mechanism of the Langmuir−Blodgett technique, the micro-parts are attached onto the substrate. The butyl acetate-water mixture is then heated to 100 °C, molten solder and air bubbles in the boiling water make it possible for the micro-parts to self-align on the substrate. This methodology could give a self-assembly yield of up to 90%, providing a practicable method for micro-assembly. 相似文献
