Abstract

A MEMS component includes, on a substrate, component structures, contact areas connected to the component structures, metallic column structures seated on the contact areas, and metallic frame structures surrounding the component structures. A cured resist layer is seated on frame structure and column structures such that a cavity is enclosed between substrate, frame structure and resist layer. A structured metallization is provided directly on the resist layer or on a carrier layer seated on the resist layer. The structured metallization includes at least external contacts of the component and being electrically conductively connected both to metallic structures and to the contact areas of the component structures.
