Claim Text:
1. A semiconductor device comprising: a first fin type active pattern formed on a substrate and extending in a first direction and including first to third parts, the first to third parts being sequentially arranged in the first direction, a height ranging from a top surface of the substrate to a top surface of the first part being greater than a height ranging from the top surface of the substrate to a top surface of the second part, and a height ranging from the top surface of the substrate to the top surface of the second part being greater than a height ranging from the top surface of the substrate to a top surface of the third part; a gate electrode extending in a second direction different from the first direction and formed at least partially on the first part; a first source/drain formed on the third part; and a field insulation layer formed on the substrate and making contact with portions of sidewalls of the first fin type active pattern, wherein sidewalls of the third part are covered by the field insulation layer, wherein the first part has a greater width than the second part at a first height from a top surface of the field insulation layer.
