Abstract:
1. A method of forming a pattern structure for a semiconductor device, comprising: forming a sacrificial mask pattern on a target layer formed on a substrate, the sacrificial mask pattern including a first line-shaped pattern extending in a first direction, a second pattern having a sacrificial pattern body spaced apart from and parallel with the first line-shaped pattern and at least a connection portion connected to the first line-shaped pattern in a second direction and a third pattern spaced apart from and parallel with the first line-shaped pattern and the second pattern; forming a spacer line on sidewalls of the first line-shaped pattern, the second pattern and the third pattern to provide spacer spaces that extend in the first direction between the spacer lines and through which the target layer is partially exposed; forming a mask pattern covering at least a portion of the connection portion of the second pattern; removing the sacrificial mask pattern from the target layer, such that the spacer lines and the mask pattern remain on the target layer; partially etching the target layer using the spacer line and the mask pattern as an etching mask to form a first line-shaped opening that continuously extends in the first direction and a second line-shaped opening that is separated discontinuous in the second direction; and forming a first line and a second line by filling the first line-shaped opening and the second line-shaped opening, the first line extending discontinuously in the first direction and having at least a cut-off portion and the second line extending continuously in the first direction adjacent to the first line and having at least a protrusion portion directed to the cut-off portion.
