Micromechanical structure, sensor and method for manufacturing the same

摘要

A micromechanical structure, such as a sensor, includes a substrate, a diaphragm, a cavity, a sacrificial layer and a terminating structure. The terminating structure is cut away in the region of the diaphragm in such a way that a media opening is located above the diaphragm. The diameter of the cavity is smaller over the entire circumference of the cavity than the diameter of the opening. A method for manufacturing the micromechanical structure is also provided.
