Patent ID: 7161237

Claim:
A semiconductor device assembly comprising: a semiconductor die having an active surface and a back surface, the active surface having a plurality of spaced conductive bumps extending transversely therefrom; and an interposer substrate having a first surface and a second, opposing surface, the interposer substrate comprising a dielectric member having a plurality of spaced recesses therein opening onto the first surface and extending through the dielectric member to a like plurality of conductive terminals comprising portions of elongated conductive traces, each of the plurality of conductive traces being disposed on the second, opposing surface and extending transversely and completely across a bottom of one of the plurality of spaced recesses; wherein at least one of the plurality of spaced conductive bumps is substantially completely received in each recess of the plurality of spaced recesses in conductive contact with a conductive terminal of the plurality of conductive terminals.
