Abstract
A method for producing sensor devices includes generating a semiconductor wafer having a plurality of sensor chips, wherein each sensor chip comprises a micro-electromechanical systems (MEMS) structure arranged at a main surface of the semiconductor wafer; forming a plurality of gas-permeable covers over the main surface of the semiconductor wafer, wherein each gas-permeable cover covers a corresponding MEMS structure of the MEMS structures and forms a cavity above the corresponding MEMS structure; and singulating the semiconductor wafer into a plurality of sensor devices.
