    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.

    摘要: An integrated circuit structure includes a lower dielectric layer; an upper dielectric layer over the lower dielectric layer; and a seal ring. The seal ring includes an upper metal line in the upper dielectric layer; a continuous via bar underlying and abutting the upper metal line, wherein the continuous via bar has a width greater than about 70 percent of a width of the upper metal line; a lower metal line in the lower dielectric layer; and a via bar underlying and abutting the lower metal line. The via bar has a width substantially less than a half of a width of the lower metal line.
