    • In a method for producing an MEMS component, wherein, in the course of producing the multilevel interconnect layer stack for connecting microelectronic circuits, micromechanical structure elements (7, 8, 9) that are to be exposed later are embedded at the same time, a cutout is subsequently produced from a substrate rear side (R) as far as the multilevel interconnect layer stack, and then the micromechanical structure elements in the multilevel interconnect layer stack are exposed through the cutout. In order to increase the process accuracy, as early as in the course of producing the multilevel interconnect layer stack or even in the front end of line, a reference mask (22) for defining a lateral position or a lateral extent of the micromechanical structure elements (7, 8, 9) to be exposed is produced, wherein the reference mask (22) is arranged on the substrate front side between the substrate and the multilevel interconnect layer stack or in a layer of the multilevel interconnect layer stack that is situated nearer to the substrate (1) in comparison with the structure element.
