Abstract: A semiconductor device includes a plurality of lines disposed on a semiconductor substrate, and remaining line patterns disposed spaced apart from the lines on extensions from the lines. The lines include first end-portions adjacent to the remaining line patterns. The remaining line patterns include second end-portions adjacent to the lines. The first end-portions and second end-portions are formed to have mirror symmetry with respect to each other.

Abstract: A non-volatile memory device includes gate structures, an insulation layer pattern, and an isolation structure. Multiple gate structures being spaced apart from each other in a first direction are formed on a substrate. Ones of the gate structures extend in a second direction that is substantially perpendicular to the first direction. The substrate includes active regions and field regions alternately and repeatedly formed in the second direction. The insulation layer pattern is formed between the gate structures and has a second air gap therein. Each of the isolation structures extending in the first direction and having a first air gap between the gate structures, the insulation layer pattern, and the isolation structure is formed on the substrate in each field region.

Abstract: A method of fabricating a nonvolatile memory device includes forming trenches in a substrate defining device isolation regions therein and active regions therebetween. The trenches and the active regions therebetween extend into first and second device regions of the substrate. A sacrificial layer is formed in the trenches between the active regions in the first device region, and an insulating layer is formed to substantially fill the trenches between the active regions in the second device region. At least a portion of the sacrificial layer in the trenches in the first device region is selectively removed to define gap regions extending along the trenches between the active regions in the first device region, while substantially maintaining the insulating layer in the trenches between the active regions in the second device region. Related methods and devices are also discussed.
