A semiconductor apparatus includes a first cell having a first interconnect structure and a second cell having a second interconnect structure. The semiconductor apparatus further includes a first plurality of conductive segments, wherein each conductive segment of the first plurality of conductive segments directly connects a first metal level of the first interconnect structure to a first metal level of the second interconnect structure. The semiconductor apparatus further includes a third cell having a third interconnect structure and a fourth cell having a fourth interconnect structure. The semiconductor apparatus further includes a second plurality of conductive segments, wherein each conductive segment of the second plurality of conductive segments directly connects a second metal level of the third interconnect structure to a second metal level of the fourth interconnect structure, and the second metal level is different from the first metal level.
