    摘要: A semiconductor device is provided that includes a semiconductor substrate, a plurality of dies formed on the semiconductor substrate, the plurality of dies being separated from one another by a first region extending along a first direction and a second region extending along a second direction different from the first direction, a dummy metal structure formed within a third region that includes a region defined by an intersection of the first region and the second region, a plurality of metal interconnection layers formed over the substrate, and a plurality of dielectric layers formed over the substrate. Each of the metal interconnection layers is disposed within each of the dielectric layers and a dielectric constant of at least one of the dielectric layers is less than about 2.6.

    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.
