Crack resistant scribe line monitor structure and method for making the same

A method and structure prevents crack propagation to the active die circuitry of a main die area during sawing around the outer periphery of the main die area. Stress relief elements, such as dummy vias, are provided in the scribe line area between the saw lane and the main die area. The dummy vias...

Zusammenfassung:A method and structure prevents crack propagation to the active die circuitry of a main die area during sawing around the outer periphery of the main die area. Stress relief elements, such as dummy vias, are provided in the scribe line area between the saw lane and the main die area. The dummy vias prevent cracks induced by the sawing process from propagating to the main die area.
