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.
Claims8
A semiconductor device comprising first and second standard cells which are arranged adjacent to each other in a first direction and which each include a fin transistor, 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,
- the second standard cell further includes at least one active fin different from the plurality of first fins and the plurality of second fins, and
- at least one of the plurality of second fins is at least one dummy fin which does not contribute to any logical function.
A semiconductor device comprising a standard cell including a fin transistor, wherein the standard cell further includes:
- a plurality of first active fins which extend in a first direction, and which are arranged in a second direction that is perpendicular to the first direction along one end of the standard cell in the first direction,
- a plurality of second active fins which extend in the first direction, and which are arranged in the second direction along the other end of the standard cell in the first direction, and
- two regions having two different conductivity types which are arranged adjacent to each other in the second direction, wherein
- the first active fins and the second active fins are arranged in both the two regions having the two different conductivity types,
- in one of the two regions that has one of the two conductivity types, a third active fin is arranged between at least one pair of the first and second active fins, and
- in the other region that has the other conductivity type, a non-active fin area where no active fins are arranged at the same position as the third fin in the first direction is provided.
