Assignee: SOCIONEXT INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC B  H

Claim 0:
1. A semiconductor integrated circuit device comprising
a circuit block including a cell row having a plurality of cells arranged in a first direction, wherein
the cell row includes:
a cell-row-terminating cell that does not contribute to a logical function of the circuit block disposed at a first end of the cell row, and
a first cell that is adjacent to the cell-row terminating cell in the first direction; and

the cell-row-terminating cell includes:
a plurality of nanowires extending in the first direction,
a plurality of pads connected to the plurality of nanowires of the cell-row terminating cell, and
a plurality of gate structures extending in a second direction perpendicular to the first direction, including a first gate structure placed at a cell end on an inner side of the circuit block, and a second gate structure adjacent to the first gate structure in the first direction; and

the first cell includes:
a plurality of nanowires extending in the first direction,
a plurality of pads connected to the plurality of nanowires of the first cell and facing the plurality of pads of the cell-row-terminating cell, and
a third gate structure adjacent to the first gate structure in the first direction.
