Abstract

A semiconductor device includes an active device region and a plurality of guard rings arranged in a first concentric pattern surrounding the active device region. The semiconductor device also includes a plurality of junctions arranged in a second concentric pattern surrounding the active device region. At least one of the plurality of junctions is arranged between two adjacent guard rings of the plurality of guard rings, and the plurality of junctions have a different resistivity than the plurality of guard rings. The semiconductor device further includes a plurality of coupling paths. At least one of the plurality of coupling paths is arranged to connect two adjacent guard rings of the plurality of guard rings.
