    摘要: Apparatus and methods for forming a heat spreader on a substrate to release heat for a semi-conductor package are disclosed. The apparatus comprises a substrate. A dielectric layer is formed next to the substrate and in contact with a surface of the substrate. A heat spreader is formed next to the substrate and in contact with another surface of the substrate. A passivation layer is formed next to the dielectric layer. A connection pad is placed on top of the passivation layer. The substrate may comprise additional through-silicon-vias. The contact surface between the substrate and the heat spreader may be a scraggy surface. The packaging method further proceeds to connect a chip to the connection pad by way of a connection device such as a solder ball or a bump.

    摘要: A semiconductor test pad interconnect structure with integrated die-separation protective barriers. The interconnect structure includes a plurality of stacked metal layers each having an electrically conductive test pad separated from other test pads by a dielectric material layer. In one embodiment, at least one metallic via bar is embedded into the interconnect structure and electrically interconnects each of the test pads in the metal layers together. The via bar extends substantially along an entire first side defined by each test pad in some embodiments. In other embodiments, a pair of opposing via bars may be provided that are arranged on opposite sides of a die singulation saw cut line defined in a scribe band on a semiconductor wafer.

    摘要: A system and method for preventing defaults during singulation is presented. An embodiment comprises a dummy metal structure located in the scribe region. The dummy metal structure comprises a series of alternating dummy lines that are connected through dummy vias. The dummy lines are offset from dummy lines in adjacent metal layers. Additionally, the dummy lines and dummy vias in the upper layers of the scribe line may be formed with larger dimensions than the dummy lines and dummy vias located in the lower layers.
