Claim Text:
1. A semiconductor device comprising: a field insulating layer on a top surface of a substrate and including a trench defined therein that extends in a first direction; and a fin-type active pattern extending from the top surface of the substrate and through the trench defined in the field insulating layer, the fin-type active pattern including a first lower pattern that contacts the substrate and a first upper pattern that contacts the first lower pattern and protrudes further from the substrate than the field insulating layer, the first upper pattern comprising a lattice modifying material that is different from the first lower pattern, and the fin-type active pattern including a first fin portion and a second fin portion that is on both sides of the first fin portion in the first direction, and the first lower pattern including a semiconductor material; and a first gate electrode intersecting the fin-type active pattern and extending in a second direction that is different from the first direction.
