Classification: CPC B  G | IPC B

Claim 10:
11. A method for producing a micromechanical component for a pressure sensor device, comprising the following steps:
mounting a frame structure on a boundary surface formed by a substrate surface of a substrate and/or by at least one intermediate layer at least partially covering the substrate surface;
mounting a diaphragm on the frame structure in such a way that an inner diaphragm side of the diaphragm borders on an interior volume, framed by the frame structure and having a reference pressure prevailing within, in such a way that the diaphragm is warped into the interior volume when a pressure prevailing on an outer diaphragm side facing away from the inner diaphragm side is above the reference pressure; and
suspending a rocker structure on the inner diaphragm side, which at least in an operating mode of the rocker structure is able to be set into a rocker motion by the diaphragm warping into the interior volume;
wherein the rocker structure is suspended on the inner diaphragm side in such a way that when the pressure prevailing on the outer diaphragm side is above the reference pressure, but below a predefined minimum operating pressure, an open gap exists respectively between at least one stop face of the rocker structure and the boundary surface, which is closed only when a pressure prevailing on the outer diaphragm side becomes greater than or equal to the minimum operating pressure, whereby the rocker structure is transferred into the operating mode.
