    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 semiconductor chip includes a semiconductor substrate; a plurality of low-k dielectric layers over the semiconductor substrate; a first passivation layer over the plurality of low-k dielectric layers; and a second passivation layer over the first passivation layer. A first seal ring is adjacent to an edge of the semiconductor chip, wherein the first seal ring has an upper surface substantially level to a bottom surface of the first passivation layer. A second seal ring is adjacent to the first seal ring and on an inner side of the semiconductor chip than the first seal ring. The second seal ring includes a pad ring in the first passivation layer and the second passivation layer. A trench ring includes at least a portion directly over the first seal ring. The trench ring extends from a top surface of the second passivation layer down to at least an interface between the first passivation layer and the second passivation layer.

    摘要: A semiconductor wafer having a multi-layer wiring structure is disclosed. The wafer comprises a plurality of chip die areas arranged on the wafer in an array and scribe line areas between the chip die areas. The scribe lines of a semiconductor wafer having USG top-level wiring layers above ELK wiring layers have at least one metal film structures substantially covering corner regions where two scribe lines intersect to inhibit delamination at the USG/ELK interface during wafer dicing operation.
