摘要
设计了一种新型横向接触式微机械RF开关,描述了其结构和工作原理.采用以电镀为主的工艺流程,并利用SU8光刻胶实现特殊器件结构,可实现Post-CMOS集成.利用模拟软件CoventorWare 2004和MEMS Pro 5.0 (包含 ANSYS 8.0)协同设计,对该器件进行了静态、模态和瞬态分析,得到吸合电压和吸合时间等重要性能参数.尤其在瞬态分析时运用了集总参数建模的方法,简化了计算.该器件的吸合电压低于30 V,在驱动电压为50 V的情况下,吸合时间达到16.1 ms.
A novel lateral DC-contact MEMS RF switch is investigated in this paper. The structure and the operation principle are described. A post-CMOS fabrication process flow is proposed and verified with CoventorWare 2004, which utilizes electroplating to form the structure of the device. SUB photoresist is used for special connections. CoventorWare 2004 and MEMS Pro 5.0 ( including ANSYS 8.0) are used to accommodate the simulation. Static, modal and dynamic simulations are conducted respectively, and the design parameters are optimized. Dynamic simulation is carried out with a novel lumped modeling approach, which greatly simplifies the computation. The simulated Pull-in voltage is lower than 30 V with a Pull-in time of 16.1 ms under an actuation voltage of 50 V.
