A semiconductor module includes a module package including a first substrate having a first semiconductor device and a second substrate having a second semiconductor device. A first outer conductor extends from the module package and is connected to the first substrate and a second outer conductor extends from the module package and is connected to the second substrate. A method for producing the semiconductor module includes attaching first outer conductors of a leadframe to a first substrate, where the first substrate includes a first semiconductor device that is attached to the first substrate either before or after attaching the first outer conductors. A second substrate is provided including a signal processing circuit and the second substrate is fastening to second outer conductors of the leadframe.
