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 11):
A method of manufacturing a semiconductor device, the method comprising:\n forming a plurality of hard mask units on a substrate such that each of the hard mask units includes at least two hard mask patterns spaced a pattern spacing distance from each other on an upper portion of the substrate; forming a plurality of spacer patterns on the substrate such that the spacer patterns are outside the hard mask units; and forming an active fin and dummy fin by etching the substrate using the hard mask patterns and the spacer patterns as etch masks, wherein a spacing distance between the active fin and an adjacent dummy fin is greater than an spacing distance between adjacent active fins.
