    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: An integrated circuit structure includes a first, a second and a third metallization layer. The first metallization layer includes a first dielectric layer having a first k value; and first metal lines in the first dielectric layer. The second metallization layer is over the first metallization layer, and includes a second dielectric layer having a second k value greater than the first k value; and second metal lines in the second dielectric layer. The third metallization layer is over the second metallization layer, and includes a third dielectric layer having a third k value; and third metal lines in the third dielectric layer. The integrated circuit structure further includes a bottom passivation layer over the third metallization layer.
