Abstract:
A semiconductor device assembly comprising:a carrier substrate having a surface; a first interposer substrate having a first surface and a second surface and at least one opening extending therebetween, said second surface of said first interposer substrate substantially facing said surface of said carrier substrate, and said first interposer substrate and said carrier substrate being electrically connected by a set of conductive elements extending transversely therebetween; a second interposer substrate having a first surface and a second surface and at least one opening extending therebetween, said first surface of said second interposer substrate substantially facing said first surface of said first interposer substrate, said first and second interposer substrates being electrically connected by another set of conductive elements extending transversely therebetween; and at least one first die and at least one second die, each having an active surface, said active surface of said at least one first die attached to said second surface of said first interposer substrate over said at least one opening thereof and electrically connected to said first surface thereof through said at least one opening thereof, said active surface of said at least one second die attached to said second surface of said second substrate over said at least one opening thereof and electrically connected to said first surface thereof through said at least one opening thereof.
