    Abstract: A method for manufacturing a micromechanical component including a substrate and a cap connected to the substrate and together with the substrate enclosing a first cavity, a first pressure prevailing and a first gas mixture with 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 the cap. The first pressure and/or the first chemical composition is adjusted in the first cavity. The access opening is sealed by introducing energy and heat into an absorbing part of the substrate or cap with the aid of a laser. A recess is formed in a surface of the substrate or of the cap facing away from the first cavity in the area of the access opening for accommodating a material area of the substrate or the cap converted into a liquid aggregate state.

  • Patent number: 9475693
    Abstract: Measures are provided which are used for stabilizing the substructure of the connecting areas of ASIC elements. These measures relate to ASIC elements including an ASIC substrate, into which electrical circuit functions are integrated, and including an ASIC layer structure on the ASIC substrate, which includes multiple wiring levels for the circuit functions, which are separated from one another by insulation layers and are interconnected via metallic plugs. At least one connecting area for placing wire bonds or for wafer bonding is implemented in at least one of the uppermost wiring levels. At least one chain of metallic plugs arranged vertically in a direct line is implemented in the ASIC layer structure below the connecting area, which extends from the uppermost wiring level up to the ASIC substrate or oxide trenches introduced therein.

  • Patent number: 9416000
    Abstract: To implement cavities having different internal pressures in joining two semiconductor elements, at least one of the two element surfaces to be joined is structured, so that at least one circumferential bonding frame area is recessed or elevated in comparison with at least one other circumferential bonding frame area. At least one connecting layer should then be applied to this structured element surface and at least two circumferential bonding frames should be structured out of this connecting layer on different surface levels of the element surface. The topography created in the element surface permits sequential bonding in which multiple cavities between the two elements may be successively hermetically sealed, so that a defined internal pressure prevails in each of the cavities.
