    • Provided is a high-sensitivity MEMS-type z-axis vibration sensor, which may sense z-axis vibration by differentially shifting an electric capacitance between a doped upper silicon layer and an upper electrode from positive to negative or vice versa when center mass of a doped polysilicon layer is moved due to z-axis vibration. Particularly, since a part of the doped upper silicon layer is additionally connected to the center mass of the doped polysilicon layer, and thus an error made by the center mass of the doped polysilicon layer is minimized, it may sensitively respond to weak vibration of low frequency such as seismic waves. Accordingly, since the high-sensitivity MEMS-type z-axis vibration sensor sensitively responds to a small amount of vibration in a low frequency band, it can be applied to a seismograph sensing seismic waves of low frequency which have a very small amount of vibration and a low vibration speed. Moreover, since the high-sensitivity MEMS-type z-axis vibration sensor has a higher vibration sensibility than MEMS-type z-axis vibration sensor of the same size, it can be useful in electronic devices which are gradually decreasing in size.
    • 提供了一种高灵敏度的MEMS型z轴振动传感器,其可以通过将掺杂的上硅层和上电极之间的电容从正向或者反向偏移来感测z轴振动,当中心质量为 掺杂多晶硅层由于z轴振动而移动。 特别地,由于掺杂的上硅层的一部分另外连接到掺杂多晶硅层的中心质量块,因此由掺杂多晶硅层的中心质量造成的误差最小化,可以敏感地响应低的振动弱 频率如地震波。 因此,由于高灵敏度的MEMS型z轴振动传感器对低频带中的少量振动敏感地作出响应,因此可以应用于地震仪中,以便感测具有极小振动频率的低频地震波 和低振动速度。 此外,由于高灵敏度的MEMS型z轴振动传感器具有比相同尺寸的MEMS型z轴振动传感器更高的振动灵敏度,所以在逐渐减小的电子设备中是有用的。
