| 摘 要： | 讨论了微机械微波/射频开关的原理、制备工艺和功能测试.微机械接触式微波/射频开关的基本结构是微波共平面波导,在制备工艺中首先考虑的是工艺兼容性,为此选择以PECVD生长的氮化硅为悬臂梁,聚酰亚胺为牺牲层.功能测试表明,该工艺制备的微机械开关的执行电压只有25V,优于同类微机械开关的指标,同时它具有良好的响应特性.

| Abstract: | The principle, fabrication processes and function test of the micromechanical MW/RF switches are presented. The fundamental structure of the switches is a coplanar waveguide. Thefabrication compatibility must be considered in the fabrication processes. Consequently, the siliconnitride deposited by PECVD is chosen as the support cantilever materials and the polyimide as asacrificial film. The Function test shows that the driving voltage of the switches is only 25V, whichis less than the driving voltage of switches of fabricated by other groups. Meanwhile, the switcheshave a good response character. |
