    Abstract: A device includes a substrate, a first structure, a second structure, a third structure and a bumper. The first structure is over the substrate. The second structure is over the substrate, wherein the second structure has a first end coupled to the first structure. The third structure is over the substrate, wherein the third structure is coupled to a second end of the second structure. The bumper is between the substrate and the third structure, wherein the bumper is a multi-layered bumper including a first conductive feature, a dielectric feature and a second conductive feature. The dielectric feature is over the first conductive feature. The second conductive feature is over the dielectric feature and electrically connected to the first conductive feature.

    Abstract: A Microelectromechanical Systems (MEMS) structure with integrated heater is disclosed. The MEMS structure with integrated heater comprises a first substrate with cavities, bonded to a second substrate, forming a plurality of sealed enclosures of at least two types. Each of the plurality of sealed enclosures is defined by the first substrate, the second substrate, and a seal-ring material, where the first enclosure type further includes at least one of a gettering element to decrease cavity pressure in the first enclosure type or an outgassing element to increase cavity pressure in the first enclosure type when activated. The first enclosure type further comprises at least one heater integrated into the first substrate adjacent to the gettering element or the outgassing element to adjust the temperature of the gettering element or the outgassing element thereby providing heating to the gettering element or the outgassing element.

    Abstract: A method is described for manufacturing a micromechanical component including a substrate and including a cap, which is connected to the substrate and, together with the substrate, encloses a first cavity, a first pressure prevailing and a first gas mixture having a first chemical composition being enclosed in the first cavity. An access opening connecting the first cavity to surroundings of the micromechanical component is formed in the substrate or cap. The first pressure and/or the first chemical composition is adjusted in the first cavity. The access opening is sealed by introducing energy or heat into an absorbing part of the substrate or cap using a laser. A layer is deposited or grown on a surface of the substrate or the cap in the area of the access opening to produce a second mechanical stress, which counteracts a first mechanical stress occurring in the case of sealed access opening.
