    摘要: A microelectromechanical systems (MEMS) sensor (52) includes a substrate (62) a movable element (58) spaced apart from the substrate (62), suspension anchors (66, 68, 70, 72) formed on the substrate (62), and compliant members (74) interconnecting the movable element (58) with the suspension anchors. The MEMS sensor (52) further includes fixed fingers (76) and fixed finger anchors (78) attaching the fixed fingers (76) to the substrate (62). The movable element (58) includes openings (64). At least one of the suspension anchors resides in at least one of the multiple openings (64) and pairs (94) of the fixed fingers (76) reside in other multiple openings (64). The MEMS sensor (52) is symmetrically formed, and a location of the fixed finger anchors (78) defines an anchor region (103) within which the suspension anchors (66, 68, 70, 72) are positioned.
