Embodiment Construction
[0016] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0017] Such as figure 1 and figure 2 As shown, a thermal-static strong recovery type MEMS four-point support suspension beam structure of the present invention, the structure includes a substrate 1, a pull-down electrode 2 for electrostatic excitation, anchor areas 31-34, a suspension main beam 4, Bending support beams 5 and 6. The suspension main beam 4 is suspended above the substrate 1 through four anchor areas 31 , 32 , 33 , 34 and bending support beams 5 and 6 at both ends.
[0018] Such as figure 1 and figure 2 As shown, the bending support beam 5 is composed of a crossbeam 51 and two groups of parallel longitudinal beams 52 , 53 and 54 , 55 . Among them, the longitudinal beam adopts wide and narrow beam design, 52 and 54 are narrow beams, and 53 and 55 are wide beams. The bending support beam 6 at the other end is structurally...
