  • Method of forming a device by removing a conductive layer of a wafer
    Publication number: 20050176163
    Abstract: A method of forming a MEMS device provides a wafer having a base, a first conductive layer, a second conductive layer, and an intermediate conductive layer. After it provides the wafer, the method removes at least a portion of the intermediate conductive layer to form a cavity between the first and second conductive layers. At least a portion of the first conductive layer is movable relative to the base to form a diaphragm, while the second conductive layer is substantially immovable relative to the base. After it forms the cavity, the method seals the cavity.
