Abstract

A semiconductor device includes a first fin type pattern and a second fin type pattern, which are isolated from each other by an isolating trench, and extend in a first direction on a substrate, respectively, a third fin type pattern which is spaced apart from the first fin type pattern and the second fin type pattern in a second direction and extends in the first direction, a field insulation film on a part of sidewalls of the first to third fin type patterns, a device isolation structure, which extends in the second direction, and is in the isolating trench, a gate insulation support, which extends in the first direction on the field insulation film between the first fin type pattern and the third fin type pattern, a gate structure, which intersects the third fin type pattern, extends in the second direction, and is in contact with the gate insulation support, wherein a height from the substrate to a bottom surface of the gate structure is greater than a height from the substrate to a bottom surface of the gate insulation support.
