    摘要: A system and a method of testing a semiconductor die is provided. An embodiment comprises a plurality of tips that each comprise a substrate with a conductive via, a first dielectric layer with vias connected to the conductive via, a second dielectric layer with vias over the first dielectric layer, and a metal layer over the second dielectric layer. Additional dielectric layers with vias may be used. This tip is electrically connected to a redistribution line that routes signals between the tip to electrical connections on a space transformation layer. The space transformation layer is electrically connected to a printed circuit board using, for example, a spring loaded connection such as a pogo pin. The space transformation layer is aligned onto the printed circuit board by a series of guidance mechanisms such as guide pins or smooth fixtures, and the planarity of the tips is adjusted by adjusting the screws.

    摘要: A system and a method of testing a semiconductor die is provided. An embodiment comprises a plurality of metal tips that are connected to a redistribution layer that fans out the pitch from the tips to metal plugs located in the substrate. The metal tips could be formed using semiconductor processes and either adding smaller layers of metal to larger layers of metal or else removing portions of one piece of metal to form the tips. The metal plugs are connected to a space transformation layer. The space transformation layer is electrically connected to a printed circuit board using, for example, a spring loaded connection such as a pogo pin. The space transformation layer is aligned onto the printed circuit board by a series of guidance mechanisms such as smooth fixtures, and the planarity of the tips is adjusted by adjusting a series of screws.

The loop-back structure includes a first bonding pad on a first surface; and a second bonding pad on the first surface, wherein the first and the second bonding pads are electrically disconnected from integrated circuit devices in the semiconductor die. A conductive feature electrically shorts the first and the second bonding pads. An additional die including an interconnect structure is bonded onto the semiconductor die. The interconnect structure includes a third and a fourth bonding pad bonded to the first and the second bonding pads, respectively. Through-wafer vias in the additional die are further connected to the third and fourth bonding pads.
