  • Publication number: 20080272372
    Abstract: A semiconductor die including a test structure is provided. The semiconductor die includes a loop-back formed on a surface of the semiconductor die. 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.

  • Publication number: 20080153187
    Abstract: A method of forming a semiconductor structure includes providing a stack structure having a first side and a second side opposite the first side. The stack structure includes a bottom wafer comprising a substrate; a plurality of through-silicon vias in the substrate; and a plurality of under bump metallurgies (UBMs) connected to the plurality of through-silicon vias, wherein the UBMs are on the first side of the stack structure. The method further includes attaching a handling wafer on the second side of the stack structure; performing a chip probing process; and removing the handling wafer from the stack structure.

  • Patent number: 7098978
    Abstract: A wide-viewing angle LCD comprises a first substrate and a second substrate disposed opposite each other with a liquid crystal layer disposed therebetween. A first electrode is disposed on the interior of the first substrate. A first protrusion or slit structure with a first pattern is formed on the first electrode. A second electrode is disposed on the interior of the second substrate. A second protrusion or slit structure with a second pattern is formed on the second electrode. The first and second patterns constitute a third pattern with at least one intersection.
