    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 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.
