    Abstract: A MEMS microphone includes a backplate that has a plurality of open areas, and a diaphragm spaced apart from the backplate. The diaphragm is deformable by sound waves to cause gaps between the backplate and the diaphragm being changed at multiple locations on the diaphragm. The diaphragm includes a plurality of anchor areas, located near a boundary of the diaphragm, which is fixed relative to the backplate. The diaphragm also includes multiple vent valves. Examples of the vent valve include a wing vent valve and a vortex vent valve.

    Abstract: The present disclosure relates to a microelectromechanical systems (MEMS) package having two MEMS devices with different pressures, and an associated method of formation. In some embodiments, the (MEMS) package includes a device substrate and a cap substrate bonded together. The device substrate includes a first trench and a second trench. A first MEMS device is disposed over the first trench and a second MEMS device is disposed over the second trench. A first stopper is raised from a first trench bottom surface of the first trench but below a top surface of the device substrate and a second stopper is raised from a second trench bottom surface of the second trench but below the top surface of the device substrate. A first depth of the first trench is greater than a second depth of the second trench.

    Abstract: The present disclosure relates to a microelectromechanical systems (MEMS) package having two MEMS devices with different pressures, and an associated method of formation. In some embodiments, the (MEMS) package includes a device substrate and a cap substrate bonded together. The bonded substrate comprises a first cavity corresponding to a first MEMS device having a first pressure and a second cavity corresponding to a second MEMS device having a different second pressure. The second cavity comprises a major volume and a vent hole connected by a lateral channel disposed between the device substrate and the cap substrate and the vent hole is hermetically sealed by a sealing structure.

    Abstract: Embodiments of mechanisms for forming a micro-electro mechanical system (MEMS) device are provided. The MEMS device includes a CMOS substrate, a cap substrate, and a MEMS substrate bonded between the CMOS substrate and the cap substrate. The MEMS substrate includes a first movable element and a second movable element. The MEMS device also includes a first closed chamber and a second closed chamber, which are between the MEMS substrate and the cap substrate. The first movable element is in the first closed chamber, and the second movable element is in the second closed chamber. A first pressure of the first closed chamber is higher than a second pressure of the second closed chamber.
