  • Patent number: 11418885
    Abstract: A micromechanical component for a sensor device or microphone device. The component includes a diaphragm support structure with a diaphragm, a cavity formed in the diaphragm support structure and adjoined by a diaphragm inner side, and a separating trench structured through the surface of the diaphragm support structure and extends to the cavity and completely frames the diaphragm, and that is sealed off media-tight and/or air-tight using at least one separating trench closure material. An etching channel is formed in the diaphragm support structure, separately from the separating trench, and extends from its first etching channel end section to its second etching channel end section. The first etching channel end section opens into the cavity, and the second etching channel end section is sealed off media-tight and/or air-tight using at least one etching channel closure structure formed on an outer partial surface of the surface of the diaphragm support structure.
