Abstract:
A method including forming hard mask patterns on a substrate; forming etch stop patterns surrounding the hard mask patterns; forming spacer patterns covering sidewalls of the etch stop patterns; removing the etch stop patterns; etching the substrate to form active and dummy fins; forming a block mask pattern layer surrounding the active and dummy fins and forming mask etch patterns on a top surface of the block mask pattern layer; etching the block mask pattern layer to form block mask patterns surrounding the active fins; etching the dummy fins; removing the block mask patterns surrounding the active fins; and depositing a device isolation film on the substrate such that the device isolation film is not in contact with the upper portions of the active fins, wherein a spacing distance between the active fin and the dummy fin is greater than an active fin spacing distance between the active fins.

Claim (Index 2):
The method as claimed in  claim 1 , wherein a width from a sidewall of each of the etch stop patterns to an outer sidewall of the hard mask pattern disposed at an outermost side of the hard mask unit is greater than the pattern spacing distance.
