    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 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.
