Abstract: A component which can be produced at wafer level has a first chip and a second chip connected thereto. The connection is (at least partially) established via a first and a second connecting structure and a first and a second contact structure of the second chip. An adaptation structure between the first chip and the first connecting structure equalizes a height difference between the first and the second contact structure.
