Abstract
The leadframe interposer is provided with an upset which is formed by shaping in a central region and enlarges the vertical dimension of the interposer there in such a way that, during the assembly of a housing stack of a plurality of semiconductor chips, the upset presses against a topside or underside of a chip housing in such a way that a compensating torque is exerted on the interposer, which prevents a possible strain or deformation when the leads are pressed onto the contact regions of the interposer. The contact regions are laterally offset with respect to one another.
