Abstract:
A semiconductor device includes a substrate including spaced-apart active regions, and device isolating regions isolating the active regions from each other, and a pillar array pattern including a plurality of pillar patterns overlapping the active regions, the plurality of pillar patterns being spaced apart from each other at an equal distance in a first direction and in a second direction intersecting the first direction, wherein the plurality of pillar patterns include first pillar patterns and second pillar patterns disposed alternatingly in the first direction and in the second direction, a shape of a horizontal cross section of the first pillar patterns being different from a shape of a horizontal cross section of the second pillar patterns.

Claim (Index 54):
A method for fabricating a semiconductor device, the method comprising:\n sequentially forming first and second mask layers on a substrate including an array region and a background region; forming core mask patterns and first background patterns in the array region and the background region, respectively, by patterning the second mask layer, wherein the core mask patterns spaced apart from each other by a first equal distance, and the first background mask patterns spaced apart from the core mask patterns by a second distance; forming a spacer film conformally covering the core mask patterns and the first background mask patterns, wherein self-aligning grooves between the core mask patterns and background grooves between the core mask patterns and the first background mask patterns are defined by the spacer film, and wherein the array region and the background region are separated along an outer surface of the spacer film formed on side surfaces of the core mask patterns; filling the self-aligning grooves and the background grooves entirely to form a filler; forming, in the array region, self-aligning mask patterns between the core mask patterns by removing a portion of the spacer film around the self-aligning grooves; forming, in the background region, a second background mask pattern between the core mask patterns and the first background mask patterns by removing a portion of the spacer film between the background grooves and the core mask patterns; patterning the first mask layer into a first mask patterns, with the core mask patterns, the self-aligning mask patterns, the first background mask patterns and the second background mask patterns as a mask; and forming pillar array patterns and background patterns in the array region and the background region, respectively, by patterning with the first mask pattern as a mask.
