Abstract: The invention relates to an inductive component. The component comprises a coil core, in particular a ferrite core, and at least one coil winding. The coil core is formed by at least two core parts, or only two core parts, in particular one core part and one additional core part. The core parts form the coil core when assembled. The core parts have respective joining surfaces which are designed to face each other when the core parts are joined. According to the invention, in the inductive component of the aforementioned type, at least one of the core parts has a through-opening. The through-opening is arranged and designed to lead heat-conducting medium into a cavity, in particular a gap, extending between the joining surfaces and to fill said cavity with the heat-conducting medium.

Abstract: A method for manufacturing a micromechanical component is proposed. In this context, at least one trench structure having a depth less than the substrate thickness is to be produced in a substrate. In addition, an insulating layer and a filler layer are produced or applied on a first side of the substrate. The filler layer comprises a filler material that substantially fills up the trench structure. A planar first side of the substrate is produced by way of a subsequent planarization within a plane of the filler layer or of the insulating layer or of the substrate. A further planarization of the second side of the substrate is then accomplished. A micromechanical component that is manufactured in accordance with the method is also described.

Abstract: A method for producing a micromechanical component is proposed, a trench structure being substantially completely filled up by a first filler layer, and a first mask layer being applied on the first filler layer, on which in turn a second filler layer and a second mask layer are applied. A micromechanical component is also proposed, the first filler layer filling up the trench structure of the micromechanical component and at the same time forming a movable sensor structure.

Abstract: An acceleration sensor having a mass which is movably supported outside its center of gravity, first electrodes on the mass and second electrodes located at a distance therefrom forming a capacitive sensor in order to determine a change in position of the mass as a function of time. At least one spring element which generates a restoring force when the mass is deflected from its neutral position is provided on the side of the mass facing the capacitive sensor. The mass may be obtained by being exposed from a material layer, and the mass is surrounded, at least at its side faces, by this material.

Abstract: A micromechanical component having at least two caverns is provided, the caverns being delimited by the micromechanical component and a cap, and the caverns having different internal atmospheric pressures. The micromechanical component and cap are hermetically joined to one another at a first specifiable atmospheric pressure, then an access to at least one cavern is produced, and subsequently the access is hermetically closed off at a second specifiable atmospheric pressure.
