Classification: CPC H | IPC H

Claim 9:
10. A semiconductor device comprising:
a substrate;
a first active pattern which extends in a first horizontal direction on the substrate, and comprises a first side wall and a second side wall opposite to the first side wall in a second horizontal direction different from the first horizontal direction;
a second active pattern which extends in the first horizontal direction on the first side wall of the first active pattern;
a third active pattern which extends in the first horizontal direction on the second side wall of the first active pattern;
a plurality of nanosheets spaced apart from each other in a vertical direction on the first active pattern;
a first insulating structure in a first trench extending in the first horizontal direction on the first side wall of the first active pattern;
a second insulating structure in a second trench extending in the first horizontal direction on the second side wall of the first active pattern, and comprising a first insulating layer on side walls and a bottom surface of the second trench, and a second insulating layer in the second trench on the first insulating layer;
a gate-cut extending in the first horizontal direction on the first insulating structure;
a gate electrode which extends in the second horizontal direction on the first, second, and third active patterns and surrounds the plurality of nanosheets in the second horizontal direction; and
a gate insulating layer between the gate electrode and the plurality of nanosheets, and between the gate electrode and the gate-cut,
wherein a distance in the second horizontal direction between the second active pattern and the first active pattern is less than a distance in the second horizontal direction between the first active pattern and the third active pattern.
