    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: 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.
