    摘要: A method for performing grinding includes selecting a target wheel loading for wafer grinding processes, and performing a grinding process on a wafer. With the proceeding of the grinding process, wheel loadings of the grinding process are measured. The grinding process is stopped after the target wheel loading is reached. The method alternatively includes selecting a target reflectivity of wafer grinding processes, and performing a grinding process on a wafer. With a proceeding of the grinding process, reflectivities of a light reflected from a surface of the wafer are measured. The grinding process is stopped after one of the reflectivities reaches the target reflectivity.

    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: A package structure includes a substrate, a first die and at least one second die. The substrate includes a first pair of parallel edges and a second pair of parallel edges. The first die is mounted over the substrate. The first die includes a third pair of parallel edges and a fourth pair of parallel edges, wherein the third pair of parallel edges and the fourth pair of parallel edges are not parallel to the first pair of parallel edges and the second pair of parallel edges, respectively. The at least one second die is mounted over the first die.
