Abstract:
A first metal layer of a semiconductor device includes a plurality of first metal lines that each extend along a first axis, and a first rail structure that extends along the first axis. The first rail structure is physically separated from the first metal lines. A second metal layer is located over the first metal layer. The second metal layer includes a plurality of second metal lines that each extend along a second axis orthogonal to the first axis, and a second rail structure that extends along the first axis. The second rail structure is physically separated from the second metal lines. The second rail structure is located directly over the first rail structure. A plurality of vias is located between the first metal layer and the second metal layer. A subset of the vias electrically interconnects the first rail structure to the second rail structure.

Claim (Index 14):
A semiconductor device, comprising:\n a first rail structure and a second rail structure that each extends in a first direction in a top view, wherein the first rail structure or the second rail structure includes a power rail or a ground rail of an Integrated Circuit (IC); a plurality of first metal lines disposed between the first rail structure and the second rail structure in the top view, wherein the first metal lines each extends in the first direction in the top view; a third rail structure and a fourth rail structure that each extends in the first direction in the top view, wherein the third rail structure is located over the first rail structure in a side view, and wherein the fourth rail structure is located over the second rail structure in the side view; a plurality of second metal lines disposed between the third rail structure and the fourth rail structure in the top view, wherein the second metal lines each extends in a second direction different from the first direction in the top view, and wherein each of the second metal lines partially overlaps with at least one of the first metal lines in the top view; a plurality of first vias that electrically connect the first rail structure to the third rail structure, wherein the first vias are spread out in the top view with respect to the first rail structure or with respect to the third rail structure; and a plurality of second vias that electrically connect the second rail structure to the fourth rail structure, wherein the second vias are spread out in the top view with respect to the second rail structure or with respect to the fourth rail structure.
