摘要:
A manufacturing method for a cap, for a hybrid vertically integrated component having a MEMS component a relatively large cavern volume having a low cavern internal pressure, and a reliable overload protection for the micromechanical structure of the MEMS component. A cap structure is produced in a flat cap substrate in a multistep anisotropic etching, and includes at least one mounting frame having at least one mounting surface and a stop structure, on the cap inner side, having at least one stop surface, the surface of the cap substrate being masked for the multistep anisotropic etching with at least two masking layers made of different materials, and the layouts of the masking layers and the number and duration of the etching steps being selected so that the mounting surface, the stop surface, and the cap inner side are situated at different surface levels of the cap structure.
