Abstract:
A method for defining a length of a fin including forming a plurality of first slice walls on a mask material layer, which is provided over the fin, using a plurality of hard mask patterns, providing a plurality of fill mask patterns self-aligned with respect to the plurality of first slice walls to expose one or more select areas between one or more pairs of adjacent ones of the plurality of first slice walls, and providing a trim mask pattern including one or more openings and self-aligned with respect to the plurality of second slice walls to expose one or more of the plurality of first slice walls may be provided.

Claim (Index 12):
A method for patterning a line shape structure to have a length, the method comprising:\n providing a plurality of line shape structures on a substrate, the plurality of line shape structures horizontally extending in a first direction; providing a mask material layer on the plurality of line shape structures; providing a first material layer on the mask material layer; providing a plurality of first hard mask patterns on the first material layer; patterning the first material layer using the plurality of first hard mask patterns to form a plurality of first slice walls, the plurality of first slice walls horizontally extending in a second direction, the second direction crossing the first direction; providing a first insulating layer on the plurality of first slice walls and the mask material layer; providing a plurality of fill mask patterns on the first insulating layer such that a first side of the plurality of fill mask patterns that extends along the second direction are aligned to central positions of corresponding ones of the plurality of first slice walls, respectively, to expose one or more select areas between one or more pairs of adjacent ones of the plurality of first slice walls; removing the first insulating layer at the exposed one or more select areas and the plurality of fill mask patterns; providing one or more second slice walls at the exposed one or more select areas; providing a second insulating layer on the first insulating layer, the plurality of first slice walls, and the one or more second slice walls; providing a trim mask pattern on the second insulating layer, the trim mask pattern including one or more openings on the second insulating layer such that a first side of the one or more openings that extend along the second direction are aligned to central positions of corresponding ones of the one or more second slice walls, respectively to expose one or more of the plurality of first slice walls; removing the one or more of the plurality of first slice walls exposed by the trim mask pattern; removing the trim mask pattern and the first and second insulating layers; patterning the mask material layer using remaining ones of the plurality of first slice walls and the one or more second slice walls to form a plurality of second hard mask patterns; and patterning the plurality of line shape structures using the plurality of second hard mask patterns.
