  • Patent number: 10023459
    Abstract: A method and apparatus are provided to prevent or reduce stiction of a MEMS device. The MEMS device may include a protrusion extending from a surface of the MEMS device. During manufacture, the protrusion may be connected across an opening in the MEMS device to a sidewall of the substrate. Before manufacture of the MEMS device is completed, at least a portion of the protrusion connecting the MEMS device to the substrate may be removed. During operation, the protrusion may provide stiction prevention or reduction for the surface from which the first protrusion may extend. A plurality of protrusions may be formed along a plurality of surfaces for the MEMS device to prevent or reduce stiction along the corresponding surfaces. Protrusions may also be formed on devices surrounding or encapsulating the MEMS device to prevent or reduce stiction of the MEMS device to the surrounding or encapsulating devices.
