    摘要: A scribe line layout design to reduce the damage caused by sawing the wafer is presented. An embodiment comprises metal plates located within the scribe lines and at least partially within the junctions of the scribe lines. Each of these metal plates has one or more slots to help relieve the pressure. Alternatively, instead of metal plates, grooves that may be filled with metal could be placed into the scribe lines. These metal plates could also be used concurrently with a seal ring for better protection during sawing.

    摘要: A method for forming an integrated circuit structure includes forming a test wafer. The step of forming the test wafer includes providing a first semiconductor substrate; and forming a first plurality of unit blocks over the first semiconductor substrate. Each of the first plurality of unit blocks includes a plurality of connection block cells arranged as an array. Each of the connection block cells includes two connection blocks, and a metal line connecting the two connection blocks. The method further includes forming a plurality of unit block boundary lines separating the first plurality of unit blocks from each other; and forming a first plurality of metal lines connecting a portion of the first plurality of unit blocks.

    摘要: A semiconductor structure having an efficient thermal path and a method for forming the same are provided. The semiconductor structure includes a protection ring over a semiconductor substrate and substantially encloses a laser fuse structure. The laser fuse structure includes a laser fuse and a connection structure connecting the fuse to integrated circuits. The protection ring is thermally coupled to the semiconductor substrate by contacts. The semiconductor structure further includes a metal plate conducting heat generated by a laser beam to the protection ring.

    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.
