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 19):
A semiconductor device, comprising:\n a first metal layer of a multi-layer interconnect structure, wherein the first metal layer includes:\n a first rail that extends in a first direction in a top view; \n a second rail that extends in the first direction in the top view; and \n a plurality of first metal lines disposed between the first rail and the second rail in the top view, wherein the first metal lines each extends in the first direction in the top view; \n a second metal layer of the multi-layer interconnect structure, wherein the second metal layer is located one level above the first metal layer and includes:\n a third rail that extends in the first direction in the top view; \n a fourth rail that extends in the first direction in the top view; \n a plurality of second metal lines disposed between the third rail and the fourth rail in the top view, wherein the second metal lines each extends in a second direction in the top view, the second direction being perpendicular to the first direction; \n at least three first vias that are disposed directly above the first rail and directly below the third rail in a side view; and at least three second vias that are disposed directly above the second rail and directly below the fourth rail in the side view.
