Claim Text:
1. A method of manufacturing a semiconductor device, the method comprising: forming an isolation layer pattern on a substrate to define first and second active fins protruding from the isolation layer pattern; forming a first anti-reflective coating (ARC) layer on the isolation layer pattern to at least partially cover sidewalls of the first and second active fins, a level of a top surface of the first ARC layer being equal to or less than levels of top surfaces of the first and second active fins and being equal to or greater than half of those of the first and second active fins; forming a first photoresist layer on the first and second active fins and the first ARC layer; removing a portion of the first photoresist layer to form a first photoresist pattern covering the first active fin and exposing the second active fin, a portion of the first ARC layer under the removed portion of the first photoresist layer being also removed to form a first ARC layer pattern; and implanting impurities into the exposed second active fin to form a first impurity region.
