    • PROBLEM TO BE SOLVED: To provide an MEMS vibrator having a high frequency accuracy.SOLUTION: An MEMS vibrator 100 includes a substrate 10, a first electrode 20 disposed above the substrate 10, a beam 34 disposed at least partially in a state having a cavity between the first electrode 20 and can oscillate with an electrostatic force in the thickness direction of the substrate 10, and a second electrode 30 having a support 32 disposed above the substrate 10 so as to support one end 34a of the beam 34. The support side face 32a supporting one end 34a of the support 32 has a bent part bending from the thickness direction of the substrate 10 in the plan view, and the one end 34a is supported by the support side face 32a including the bent part.
    • 要解决的问题:提供具有高频精度的MEMS振动器。 解决方案:MEMS振动器100包括基板10,设置在基板10上方的第一电极20,至少部分地设置在第一电极20之间具有空腔的状态的光束34,并且可以以静电力摆动 基板10的厚度方向,以及具有设置在基板10上方的支撑体32以支撑梁34的一端34a的第二电极30.支撑支撑体32的一端34a的支撑侧面32a具有弯曲 在平面图中从基板10的厚度方向弯曲的部分,一端34a由包括弯曲部的支撑侧面32a支撑。 版权所有(C)2013,JPO&INPIT
