Abstract:
1. An MEMS package comprising at least one chip having MEMS structures and at least one electrical connection pad on its top side, comprising a covering plate having side edges and a modulus of elasticity of at least 20 GPa, comprising a frame structure, which comprises a polymer and the material of which has a modulus of elasticity of at most 5 GPa and which is arranged between the chip and the covering plate in such a way that a closed cavity which receives the MEMS structures is formed, comprising solderable or bondable electrical contacts arranged on the outer side of the covering plate which faces away from the chip, comprising an electrical connection structure, which electrically conductively connects the at least one connection pad to the contacts, wherein the connection structure is led around the side edges of the covering plate, wherein, at at least one side of the MEMS package, the edge of the covering plate is drawn back relative to the edge of the chip, wherein the connection structures bear at least in part on the top side of the chip and on the outer side of the covering plate, and wherein the connection structure is made by metallization and includes a conductor track applied on the top side of the chip, the conductor track extending between a respective surface of the chip and the frame structure out of the closed cavity.
