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 1):
A method of manufacturing a semiconductor device, the method comprising:\n forming hard mask patterns on a substrate such that forming the hard mask pattern includes forming a plurality of hard mask units, each hard mask unit having at least two hard mask patterns that are spaced a pattern spacing distance from each other and the hard mask units being separated from each other by a spacing distance that is greater than the pattern spacing distance; forming etch stop patterns surrounding the hard mask patterns of the hard mask units; forming spacer patterns covering sidewalls of the etch stop patterns; removing the etch stop patterns; etching the substrate using the hard mask patterns and the spacer pattern as etch masks to form at least one active fin unit that includes at least two active fins and to form dummy fins disposed on both sides of the at least one active fin unit; forming a block mask pattern layer surrounding the active fins and the dummy fins and forming mask etch patterns in regions including upper portions of the active fins on a top surface of the block mask pattern layer; etching the block mask pattern layer using the mask etch patterns to form block mask patterns surrounding the active fins; etching the dummy fins using the block mask patterns; 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 one active fin and an adjacent dummy fin is greater than an active fin spacing distance between adjacent active fins.
