Patent ID: 7589008

Claim:
A method for manufacturing a microelectronic workpiece, the workpiece including a microelectronic substrate having a front side, a backside, and a plurality of microelectronic dies, the individual dies including an integrated circuit and a plurality of terminals operatively coupled to the integrated circuit, the method comprising: forming a blind hole in the substrate in alignment with one of the terminals, the blind hole extending from the front side of the substrate to an intermediate depth in the substrate; applying an isolation material to at least a portion of the blind hole, wherein the isolation material is applied using a pulsed layer deposition process; constructing an electrically conductive interconnect in at least a portion of the blind hole by depositing a solder material into the blind hole and in electrical contact with the terminal; and removing material from the backside of the substrate to thin the substrate either before or after forming the blind hole.
