An integrated circuit (IC) fabrication flow including a multilevel metallization scheme wherein one or more metal layer members of a scribelane structure are formed according to one or more design constraints. A total thickness of the metal layer members of the scribelane structure along a dicing path may be limited to a threshold value to optimize dicing separation yields in a dicing operation.
