Claim 4:
5. The semiconductor device of claim 4,
wherein:
the first cell is a first dual-mode cell;
each of the second back side power rail, the third back side power rail, and the fourth back side power rail is at least partially aligned relative to the second direction;
a top portion of the first dual-mode cell relative to the second direction at least partially overlaps the first back side power rail;
a bottom portion of the first dual-mode cell relative to the second direction at least partially overlaps the second back side power rail, the third back side power rail, and the fourth back side power rail;
a top portion of a first single-mode cell relative to the second direction at least partially overlaps the second back side power rail, the third back side power rail, and the fourth back side power rail; and
a bottom portion of the first single-mode cell relative to the second direction at least partially overlaps the fifth fourth back side power rail.
