Abstract:
1. A mechanical component, comprising: a first electrode within a silicon semiconductor substrate; a diaphragm having an epitaxy layer and a second electrode; a first layer on the diaphragm and the semiconductor substrate; a cavity buried between the first electrode and the second electrode; and a second layer, which includes polysilicon, situated on the first layer above an edge region of the diaphragm, the second layer being configured as a spring-type suspension of the diaphragm in at least one section of the edge region of the diaphragm, and wherein the second layer is structured into multiple elements that are not connected to each other and that are at least one of spatially restricted, which jointly form the spring-type suspension of one of the diaphragm and the second electrode, and allow an electrical contacting of the second electrode; wherein the diaphragm is held above the first electrode by the first layer so as to allow movement, and the second electrode is laterally set apart from the semiconductor substrate, and wherein the micromechanical component is made by performing the following:
