Patent ID: 6841418

Claim:
A method for packaging microelectronic substrates, comprising: positioning a first microelectronic substrate proximate to a second microelectronic substrate, the first microelectronic substrate having a first surface with a first connection site and further having a second surface facing opposite the first surface, the second microelectronic substrate having a first surface with a second connection site and further having a second surface facing opposite the first surface; coupling the first microelectronic substrate to the second microelectronic substrate to form a substrate assembly with the first surface of the first microelectronic substrate facing toward the second surface of the second microelectronic substrate; and sequentially disposing at least first and second portions of a conductive material on the substrate assembly to build up a conductive structure connected between the first connection site of the first microelectronic substrate and the second connection site of the second microelectronic substrate.
