Patent ID: 7928550

Claim:
A semiconductor apparatus comprising: a first semiconductor chip having terminals in first locations; a second semiconductor chip having a height, and terminals in second locations; an insulating flexible interposer, integral with conductive traces, having a top and a bottom surface, a central planar rectangular area, each side of the rectangle having a wing bent at an angle from the central plane; the central area having metal studs on the top and the bottom surface, the studs on the top surface matching the first terminal locations and the studs on the bottom surface matching the second terminal locations; the central area further having conductive vias extending from the top to the bottom surface; the side wings having contact pads with metallic connectors on the bottom surface in third locations; the terminals of the first chip contacting the studs of the top interposer surface; the terminals of the second chip contacting the studs of the bottom interposer surface; an insulating substrate having attachment sites matching the third locations; the second chip adhering to the substrate so that the attached interposer faces away from the substrate; the interposer side wings having a convex bending downwardly along the second chip height and a concave bending over the substrate; and the connectors on the interposer side wings being attached to the matching substrate sites.
