Semiconductor device and method for fabricating the same

There is provided a semiconductor device having enhanced operation performance by utilizing a cut region where a gate cut is implemented. There is provided a semiconductor device comprising a first active pattern, a second active pattern, a third active pattern, and a fourth active pattern, all of which extend in parallel in a first direction, and are arranged along a second direction intersecting the first direction; a first gate electrode extended in the second direction on the first to fourth active patterns a first cut region extended in the first direction between the first active pattern and the second active pattern to cut the first gate electrode and a second cut region extended in the first direction between the third active pattern and the fourth active pattern to cut the first gate electrode, wherein one or more first dimensional features related to the first cut region is different from one or more second dimensional features related to the second cut region.
