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 1):
A method for defining a length of a fin that protrudes from a substrate, the method comprising:\n providing a mask material layer on the fin, the fin protruding from the substrate and horizontally extending in a first direction; forming a plurality of first slice walls on the mask material layer using a plurality of hard mask patterns, 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 and to be 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; 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 between one or more corresponding pairs of the plurality of first slice walls at the exposed one or more select areas, respectively; 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 including one or more openings on the second insulating layer such that the trim mask pattern is self-aligned with respect to the one or more second slice walls 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 fin cut mask patterns; and cutting the fin to have a length using the plurality of fin cut mask patterns.
