Abstract
In one embodiment, an integrated circuit device includes an active area encompassed by a seal ring. The seal ring may include a deep moat formed on an outer edge of the seal ring. The deep moat may have a depth that extends substantially to the substrate to prevent cracks from propagating into the active area. Alternatively or in addition, the seal ring may include redundant vias.
