MEMS DEVICE AND METHOD OF FABRICATION

摘要

A MEMS device (100, 300) and method of fabrication including a plurality of structural tie bars (108, 303, 304) for added structural integrity. The MEMS device includes an active layer (202) and a substrate (102) having an insulating material (204) formed therebetween, first and second pluralities of stationary electrodes (103, 105) and a plurality of moveable electrodes (107) in the active layer. A plurality of interconnects (106, 301, 302) are electrically coupled to a second surface of each of the first and second pluralities of stationary electrodes. A plurality of anchors (226) fixedly attach a first surface of each of the first and second pluralities of stationary electrodes to the substrate. A first structural tie bar couples a second surface of each of the first plurality of stationary electrodes and a second structural tie bar couples a second surface of each of the second plurality of stationary electrodes.
