Abstract
A semiconductor structure includes a first circuit region; a first inner seal ring at least partially surrounding the first circuit region; and an outer seal ring at least partially surrounding the first inner seal ring. The outer seal ring includes a first corner and a substantially triangular corner seal ring (CSR) structure at the first corner. The first inner seal ring includes a second corner adjacent to and spaced away from the CSR structure. The semiconductor structure further includes a first region between a first side of the first corner and a first side of the second corner that is parallel to the first side of the first corner, and multiple functional patterns in the first region.
