Assignee: SK HYNIX INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a slit pattern and a trench pattern disposed to extend 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,
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;
a fourth channel plug between the third channel plug and the trench pattern; and
a fifth channel plug traversed by the trench pattern,
wherein:
a top surface shape of the first channel plug is an elliptical shape,
a top surface shape of each of the third channel plug and the fourth channel plug is substantially a circle shape,
a top surface shape of the fifth channel plug is substantially a separated circle shape separated by the trench pattern, and
a long axis direction of the first channel plug and the first direction form an acute angle.
