Abstract
A semiconductor structure includes a substrate; a seal ring region around a circuit region over the substrate, wherein the seal ring region includes a sealing region and a transition region, and wherein the transition region is disposed between the sealing region and the circuit region; and a stack of metal layers disposed over the circuit region, the transition region and the sealing region. A metal layer of the stack of metal layers includes metal seal rings disposed in the sealing region including a first section along a first direction and a second section along a second direction, wherein the second direction is substantially perpendicular to the first direction; and metal transition lines disposed in the transition region along the first section and the second section, wherein the metal transition lines are oriented lengthwise along the first direction.
