Abstract:
1. A pattern structure for a semiconductor device, comprising: a plurality of first patterns, each of the first patterns extending in a first direction in the shape of a line, neighboring first patterns being spaced apart from each other by a gap distance, the plurality of first patterns including a plurality of trenches in parallel with the line shapes, respective trenches being between neighboring first patterns, the plurality of trenches including long trenches and short trenches alternately arranged in a second direction substantially perpendicular to the first direction; at least one second pattern, the at least one second pattern being coplanar with the first patterns, the first patterns and the at least one second pattern each including an active region of a semiconductor substrate, end portions of the first patterns being connected to the at least one second pattern such that the end portions of the first patterns are each integrally connected to the at least one second pattern; and a third pattern spaced apart from the first patterns and the at least one second pattern, the third pattern having a width larger than those of the first patterns.
