A method for manufacturing a pressure sensor having a pressure-sensitive medium. The method includes: providing a pressure sensor having a pressure sensor element, which is arranged in a receiving space of a housing of the pressure sensor; filling the receiving space with a pressure-sensitive medium; applying a second medium, which is immiscible with the pressure-sensitive medium, to a surface of the pressure-sensitive medium; forming a membrane in a boundary region between the pressure-sensitive medium and the second medium by way of a phase-transfer reaction between a first reactant and a second reactant, at least the first reactant or the second reactant being dissolved in the pressure-sensitive medium or in the second medium. A pressure sensor manufactured by the method is also described.

A micromechanical component. The micromechanical component includes: a substrate; a frame structure which frames a partial surface of the substrate and/or an interlayer applied to the substrate, at least one electrode being mounted on the framed partial surface and/or interlayer; a pressure-sensitive membrane on which an external pressure acts and which brings about a deformation, wherein a self-supporting area of the membrane spans the framed partial surface and/or interlayer, the self-supporting area having at least one movable counterelectrode directed toward the framed partial surface and/or interlayer; and a sealed cavity having a reference pressure, surrounded by the membrane and the frame structure; wherein the self-supporting area of the membrane has local reinforcement structures for increasing a membrane thickness of the self-supporting area, the local reinforcement structures being mounted in particular regions of the self-supporting area where the membrane thickness of the self-supporting area changes.

A method for producing a plurality of sensor devices. The method includes: furnishing a substrate having contact points in a plurality of predetermined regions for sensor chips; disposing the sensor chips in the predetermined regions on the substrate, and electrically contacting the sensor chips to the contact points; attaching a frame structure with an adhesive material on the substrate and between the sensor chips, the frame structure proceeding laterally around the sensor chips, the frame structure extending, after attachment, vertically beyond the sensor chips and forming a respective cavity for at least one of the sensor chips, and a membrane spanning at least one of the cavities for the sensor chips so as to cover it; and singulating the substrate, or the frame structure and the substrate, around the respective cavities into several sensor devices.

A method for manufacturing a sensor including a sensing element and a housing, the housing including an interior space, which is accessible through a housing opening, and the sensing element being situated in the interior space and being designed to detect a property and/or a composition of an ambient medium of the sensor. The method includes filling the interior space with a protective medium through the housing opening, the protective medium being designed to transfer the property and/or the composition of the ambient medium to the sensing element. The method includes fixing a preferably flexible diaphragm at or in the housing opening preferably for sealing the housing opening, the diaphragm including at least one diaphragm opening. The method includes sealing the at least one diaphragm opening.

A method for manufacturing a sensor. The sensor includes a sensing element and a housing, the housing including an interior space, which is accessible through a housing opening, and the sensing element being situated in the interior space and being designed to detect a property and/or a composition of an ambient medium of the sensor. The method includes filling the interior space with a protective medium through the housing opening, the protective medium being designed to transfer the property and/or the composition of the ambient medium to the sensing element; fixing a preferably flexible diaphragm at or in the housing opening preferably for sealing the housing opening, the diaphragm including at least one diaphragm opening; and sealing the at least one diaphragm opening. A sensor, which is manufactured according to this method, is also described.

A bonding pad layer system is deposited on a semiconductor chip as a base, for example, a micromechanical semiconductor chip, in which at least one self-supporting dielectric membrane made up of dielectric layers, a platinum conductor track and a heater made of platinum is integrated. In the process, the deposition of a tantalum layer takes place first, upon that the deposition of a first platinum layer, upon that the deposition of a tantalum nitride layer, upon that the deposition of a second platinum layer and upon that the deposition of a gold layer, at least one bonding pad for connecting with a bonding wire being formed in the gold layer. The bonding pad is situated in the area of the contact hole on the semiconductor chip, in which a platinum conductor track leading to the heater is connected using a ring contact and/or is connected outside this area.
