    Abstract: There is provided a semiconductor device to enhance operating characteristics by reducing parasitic capacitance between a gate electrode and other nodes. The semiconductor device includes: a substrate including an active region, and a field region directly adjacent to the active region; a first fin-type pattern protruding from the substrate in the active region; a first gate electrode disposed on the substrate, intersecting with the first fin-type pattern and including a first portion and a second portion, the first portion intersecting with the first fin-type pattern; a second gate electrode disposed on the substrate, intersecting with the first fin-type pattern and including a third portion and a fourth portion, the fourth portion facing the second portion, and the third portion intersecting with the first fin-type pattern and facing the first portion; a first interlayer insulating structure disposed between the first portion and the third portion, being on the substrate, and having a first dielectric constant; and a second interlayer insulating structure disposed between the second portion and the fourth portion, being on the substrate, and having a second dielectric constant which is different from the first dielectric constant.
