摘要:
The present invention describes a device having a housing and at least one electrical component, the housing having at least one of the electrical components and being filled at least partially by a passivating agent. Furthermore, it is provided that the electrical component is covered at least partially by the passivating agent. Now, the crux of the present invention is that an additional material layer is applied on top of the passivating agent. Using this additional material layer, a device is able to be implemented in a simple and cost-effective construction, that is resistive to environmental damages. This makes possible using electrical components in corrosive environments.

A manufacturing method for a micromechanical semiconductor element includes providing on a semiconductor substrate a patterned stabilizing element having at least one opening. The opening is arranged such that it allows access to a first region in the semiconductor substrate, the first region having a first doping. Furthermore, a selective removal of at least a portion of the semiconductor material having the first doping out of the first region of the semiconductor substrate is provided. In addition, a membrane is produced above the first region using a first epitaxy layer applied on the stabilizing element. In a further method step, at least a portion of the first region is used to produce a cavity underneath the stabilizing element. In this manner, the present invention provides for the production of the patterned stabilizing element by means of a second epitaxy layer, which is applied on the semiconductor substrate.

A method for producing a micromechanical diaphragm sensor includes providing a semiconductor substrate having a first region, a diaphragm, and a cavity that is located at least partially below the diaphragm. Above at least one part of the first region, a second region is generated in or on the surface of the semiconductor substrate, with at least one part of the second region being provided as crosspieces. The diaphragm is formed by a deposited sealing layer, and includes at least a part of the crosspieces.

摘要:
Proposed is a method for manufacturing micromechanical sensors and sensors manufactured by this method, where openings are introduced into a semiconductor substrate. After the openings are introduced into the semiconductor substrate, a subsequent temperature treatment is carried out, in which the openings are converted into voids in the depth of the substrate.
摘要:
A method is for producing a semiconductor component, e.g., a multilayer semiconductor element, e.g., a micromechanical component, e.g., a pressure sensor, having a semiconductor substrate, e.g., made of silicon, and a semiconductor component produced according to the method. To reduce the production cost of such a semiconductor component, in a first step a first porous layer is produced in the semiconductor component, and in a second step a hollow or cavity is produced under or from the first porous layer in the semiconductor component, with the hollow or cavity capable of being provided with an external access opening.
摘要:
A micromechanical component in which lateral deformations, i.e., deformations of the component parallel to its two main surfaces, are concentrated in a defined area of the component structure, making it possible to decouple lateral and vertical stresses in the component. The component structure includes at least one bellows-like structure in which lateral deformations of the component are concentrated. A pressure sensor having a micromechanical component of this type may be used, for example, for measured-value detection.
