Abstract:
An interposer for electrically connecting a leadframe of a first semiconductor chip placed above the interposer and a leadframe of a second semiconductor chip placed below the interposer, the leadframes being pressure-connected to the interposer and having leads, the interposer comprising:an interposer body of generally planar extent with mutually opposite surfaces and electrically conductive contact regions formed on the mutually opposite surfaces, said contact regions of the interposer effecting an electrically conductive connection between the respective leads of the leadframes; said interposer body being formed with at least one upset, formed and disposed to engage on a housing of a semiconductor chip in a leadframe connected to the interposer body; said contact regions of said interposer body being offset with respect to one another in the planar extent of said interposer body, said contact regions and said upset being disposed relative to one another to compensate for a torque generated by forces exerted on said contact regions by the leadframes connected to the interposer with a force exerted on said upset by at least one housing of one of the semiconductor chips in the leadframes.
