1. An integrated circuit structure, comprising:
a first power rail extending in a first direction;
a second power rail extending in the first direction, and being separated from the first power rail in a second direction different from the first direction;
a third power rail extending in the first direction, and being between the first power rail and the second power rail;
a fourth power rail extending in the first direction, being separated from the first power rail, the second power rail and the third power rail in the second direction;
a first cell in a first row, the first row extending in the first direction, and being between the first power rail and the second power rail;
a second cell in a second row, the second row extending in the first direction, and being between the first power rail and the second power rail; and
a third cell in the first row and the second row, the third cell being next to the first cell and the second cell,
wherein the first cell and the second cell are configured to share the third power rail, and the third power rail overlaps a common border between the first cell and the second cell.
