Abstract:
1. A MEMS chip package, comprising: a first chip having a first chip surface and a second chip surface, which is opposite the first chip surface of the first chip; a second chip having a first chip surface and a second chip surface, which is opposite the first chip surface of the second chip; a first coupling element, which couples the first chip surface of the second chip to the first chip surface of the first chip, so that a first cavity is defined between the first chip and the second chip; and a first redistribution layer, which is mounted on the second chip surface of the second chip and which is configured to provide contact with a substrate, wherein one chip of the first chip and the second chip has (i) at least one microelectromechanical structure (MEMS) element which is produced on the first chip surface of said one chip, and (ii) a frame element, produced between the first chip surface and the second chip surface of said one chip, which encloses the at least one microelectromechanical structure (MEMS) element, and wherein the other chip of the first chip and second chip has (i) a potting compound layer, (ii) a control circuit, embedded in the potting compound layer, which is configured to drive the at least one microelectromechanical structure element, and (iii) a third redistribution layer, which is mounted on the first chip surface of said other chip.
