Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. The semiconductor device of claim 1, further comprising:
cells that abut one another;
a power filler region; and
a plurality of front side power rails at the front side including the first front side power rail that extend over the cells and the power filler region; and
wherein:
the first back side power rail, the second back side power rail, and the third back side power rail each extend beneath the cells and the power filler region; and
a first set of the cells extend relative to the second direction so that a top portion of the first set of the cells relative to the second direction is partially aligned with the first back side power rail and a bottom portion of the first set of the cells is partially aligned with the second back side power rail;
a second set of the cells extend relative to the second direction so that a top portion of the second set of the cells relative to the second direction is partially aligned with the second back side power rail and a bottom portion of the second set of the cells is partially aligned with the third back side power rail; and
the plurality of front side power rails correspondingly connect to the first back side power rail, the fourth back side power rail, and the third back side power rail in the power filler region.
