Claim 12:
13. A semiconductor device comprising:
a slit pattern and a trench pattern extending substantially in parallel with each other in a first direction; and
channel plugs between the slit pattern and the trench pattern,
wherein the channel plugs comprise:
a first channel plug adjacent to the slit pattern, the first channel plug having an elliptical top surface shape or an elliptical cross-sectional shape;
a second channel plug between the first channel plug and the trench pattern;
a third channel plug between the second channel plug and the trench pattern; and
a fourth channel plug between the third channel plug and the trench pattern,
wherein a first distance between the slit pattern and the first channel plug is greater than a second distance between the first channel plug and the second channel plug.
