    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.

    摘要: A MEMS sensor (20, 86) includes a support structure (26) suspended above a surface (28) of a substrate (24) and connected to the substrate (24) via spring elements (30, 32, 34). A proof mass (36) is suspended above the substrate (24) and is connected to the support structure (26) via torsional elements (38). Electrodes (42, 44), spaced apart from the proof mass (36), are connected to the support structure (26) and are suspended above the substrate (24). Suspension of the electrodes (42, 44) and proof mass (36) above the surface (28) of the substrate (24) via the support structure (26) substantially physically isolates the elements from deformation of the underlying substrate (24). Additionally, connection via the spring elements (30, 32, 34) result in the MEMS sensor (22, 86) being less susceptible to movement of the support structure (26) due to this deformation.
