  • Patent number: 11084716
    Abstract: A method for producing a micromechanical component having a substrate and a cap that are connected to each other and that enclose a first cavity, where a first pressure prevails inside the first cavity and a first gas mixture having a first chemical composition is enclosed within the first cavity, includes, in a first method step, developing in the substrate or cap an access opening connecting the first cavity to an environment of the micromechanical component, in a second method step, setting the first pressure and/or the first chemical composition in the first cavity, in a third method step, sealing the access opening using a laser by introduction of energy or heat into an absorbing part of the substrate or the cap, and, in a fourth method step, performing a thermal treatment of the substrate or the cap, thereby reducing temperature gradients in the substrate or in the cap.

  • Patent number: 10207366
    Abstract: A method is described for manufacturing a micromechanical component including a substrate and a cap connected to the substrate, the cap, together with the substrate, enclosing 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 in 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 or heat into an absorbing part of the substrate or of the cap with the aid of a laser. The introduction of the energy or heat is controlled with the aid of a laser beam, which includes a spatial laser pulse expansion.

  • Patent number: 10017375
    Abstract: A method is provided 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 in the cap. The first pressure and/or the first chemical composition are adjusted in the first cavity. The access opening is sealed by introducing energy and heat into an absorbing part of the substrate or the 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 reducing local stresses occurring at a sealed access opening.

  • Patent number: 9919919
    Abstract: A method for manufacturing a micromechanical component including a substrate and a cap, which is connected to the substrate and, together with the substrate, encloses a cavity, a pressure prevailing and gas mixture having a chemical composition being enclosed in the cavity. An access opening connecting the to surroundings of the micromechanical component is formed in the substrate or in the cap. The pressure and/or chemical composition are/is adjusted in the cavity. The access opening is sealed by introducing energy or heat into an absorbing part of the substrate or of the cap with the aid of a laser. A layer is deposited on or grown on a surface of the substrate or of the cap in the area of the access opening for mixing with a material area of the substrate or of the cap, which is converted into a liquid aggregate state.
