Abstract
Disclosed herein is a semiconductor device including two standard cells which are arranged adjacent to each other in an X direction. One of the two standard cells includes a plurality of first fins which extend in the X direction, and which are arranged along a boundary between the two standard cells in a Y direction. The other standard cell includes a plurality of second fins which extend in the X direction, and which are arranged along the boundary between the two standard cells in the Y direction. The plurality of second fins includes a dummy fin.

A semiconductor device comprising first and second standard cells which are arranged adjacent to each other in a first direction, wherein:
- the first standard cell includes a plurality of first fins which extend in the first direction, and which are arranged along a boundary between the first and second standard cells in a second direction that is perpendicular to the first direction,
- the second standard cell includes a plurality of second fins which extend in the first direction, and which are arranged in the second direction along the boundary between the first and second standard cells such that each of the plurality of second fins is aligned with an associated one of the plurality of first fins, wherein the plurality of second fins include at least one dummy fin and at least one first active fin,
- the second standard cell further includes at least one second active fin different from the plurality of first fins and the plurality of second fins, wherein the at least one second active fin, the at least one dummy fin and one of the plurality of first fins are aligned with each other in the first direction, and
- the first and second standard cells include a first power supply line and a second power supply line having a different potential than the first power supply line, both extending in the first direction.
A semiconductor device comprising first and second standard cells which are arranged adjacent to each other in a first direction, wherein:
- the first standard cell includes a plurality of first fins which extend in the first direction, and which are arranged along a boundary between the first and second standard cells in a second direction that is perpendicular to the first direction,
- the second standard cell includes a plurality of fin transistors, fins of the plurality of fin transistors extend in the first direction and are arranged in the second direction along the boundary between the first and second standard cells such that each of the fins of the plurality of fin transistors is aligned with an associated one of the plurality of first fins in the first direction, wherein the plurality of fin transistors include at least one non-active transistor which does not contribute to any logical function of the second standard cell and at least one first active transistor,
- the second standard cell further includes at least one second active transistor different from the plurality of fin transistors, wherein a fin of the at least one non-active transistor and a fin of the at least one second active transistor are aligned with each other in the first direction, and
- the first and second standard cells include a first power supply line and a second power supply line having a different potential than the first power supply line, both extending in the first direction.
