    摘要: A method for fabricating a MEMS is described as follows. A substrate is provided, including a circuit region and a MEMS region separated from each other. A first metal interconnection structure is formed on the substrate in the circuit region, and simultaneously a first dielectric structure is formed on the substrate in the MEMS region. A second metal interconnection structure is formed on the first metal interconnection structure, and simultaneously a second dielectric structure, at least two metal layers and at least one protection ring are formed on the first dielectric structure. The metal layers and the protection ring are formed in the second dielectric structure and the protection ring connects two adjacent metal layers to define an enclosed space between two adjacent metal layers. The first dielectric structure and the second dielectric structure outside the enclosed space are removed to form a MEMS device in the MEMS region.

    摘要: A microelectromechanical system (MEMS) structure and a fabricating method thereof are described. The MEMS structure includes a fixed part and a movable part. The fixed part is disposed on and connects with a substrate. The movable part including at least two first metal layers, a first protection ring and a first dielectric layer is suspended on the substrate. The first protection ring connects two adjacent first metal layers, so as to define a first enclosed space between the two adjacent first metal layers. The first dielectric layer is disposed in the enclosed space and connects the two adjacent first metal layers.

    摘要: The present invention relates to an integrated structure for a MEMS device and a semiconductor device and a method of fabricating the same, in which an etch stopping element is included on a substrate between the MEMS device and the semiconductor device for protecting the semiconductor device from lateral damage when an oxide releasing process is performed to fabricate the MEMS device. The etch stopping element has various profiles and is selectively formed by an individual fabricating process or is simultaneously formed with the semiconductor device in the same fabricating process. It is a singular structure or a combined stacked multilayered structure, for example, a plurality of rows of pillared etch-resistant material plugs, one or a plurality of wall-shaped etch-resistant material plugs, or a multilayered structure of a stack of which and an etch-resistant material layer.
