MEMS DEVICE AND MANUFACTURING METHOD THEREOF

A MEMS device and a method for manufacturing the MEMS device are provided. The MEMS device includes a cap sheet and a device sheet. The device sheet includes a silicon substrate, at least two device structure layers, and at least one conductive structure layer, and each two adjacent device structure layers are coupled via a corresponding conductive structure layer. The device sheet defines a functional cavity having a first region, a second region, and a third region. The at least two device structure layers and the at least one conductive structure layer each are across the first region, the second region, and the third region, and the at least two device structure layers and the at least one conductive structure layer cooperatively form a first movable structure in the first region, define an anchor point in the second region, and form a second movable structure in the third region.
