Abstract
A semiconductor device includes a substrate and a metallization layer. The substrate has an active region that includes opposite first and second edges. The metallization layer is disposed above the substrate, and includes a pair of metal lines and a metal plate. The metal lines extend from an outer periphery of the active region into the active region and toward the second edge of the active region. The metal plate interconnects the metal lines and at least a portion of which is disposed at the outer periphery of the active region.
