Abstract
An electronic device has, as a multichip module, two or more semiconductor chips that are integrated into a leadframe such that a placement side of the leadframe and the active top sides of the circuit chips are flush and have a common fine wiring plane. The leadframe is arranged as an expanded semiconductor chip on a rewiring substrate.
