    摘要: An electrical fuse and a method for forming the same are provided. The electrical fuse includes a dielectric layer over a shallow trench isolation region and a contact plug extending from a top surface of the dielectric layer to the shallow trench isolation region, wherein the contact plug comprises a middle portion substantially narrower than the two end portions. The contact plug forms a fuse element. The electrical fuse further includes two metal lines in a metallization layer on the dielectric layer, wherein each of the two metal lines is connected to different ones of the end portions of the contact plug.

    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.
