Claim 10:
11. 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 field insulating film surrounding a part of side surfaces of the first to fourth active pattern,
a first gate electrode provided on the first to fourth active patterns and extending in the second direction;
a first gate dielectric film interposed between the first to fourth active patterns and the first gate electrode, and between the field insulating film and the first gate electrode;
a first cut region that extends in the first direction between the first active pattern and the second active pattern to cut the first gate electrode and the first gate dielectric film;
a second cut region that extends in the first direction between the third active pattern and the fourth active pattern to cut the first gate electrode and the first gate dielectric film; and
a third cut region that extends in the first direction between the second active pattern and the third active pattern to cut the first gate electrode and the first gate dielectric film,
wherein a first width of the first cut region in the second direction at the top surface of the first gate electrode, a second width of the second cut region in the second direction at the top surface of the first gate electrode, and a third width of the third cut region in the second direction at the top surface of the first gate electrode are different from each other,
wherein a first length of the first cut region from a bottom surface of the first cut region to the top surface of the first gate electrode, a second length of the second cut region from a bottom surface of the second cut region to the top surface of the first gate electrode, and a third length of the third cut region from a bottom surface of the third cut region to the top surface of the first gate electrode are different from each other, and
wherein the first length of the first cut region, the second length of the second cut region, and the third length of the third cut region are higher than a fourth length from a top surface of the field insulating film to the top surface of the first gate electrode.
