The scribe line structure for wafer dicing according to the present invention includes a plurality of metal structures arranged up-and-down on a substrate in a dielectric layer, and an upper one of the metal structures has a lower metal density than a lower one of the metal structures. In another aspect, the scribe line structure for wafer dicing includes a plurality of metal structures arranged up-and-down on a substrate in a dielectric layer, and each of the metal structures has a lower metal density on a dicing path for the wafer dicing than not on the dicing path. The scribe line structure can effectively avoid interlayer delamination or peeling issue caused by a dicing process, especially on a low-k/Cu wafer. |
