Classification: CPC H | IPC H

Claim 16:
17. A semiconductor device comprising:
a substrate including a cell region and a peripheral region;
cell active patterns on the cell region of the substrate;
peripheral active patterns on the peripheral region of the substrate;
a bumper pattern disposed between the cell active patterns and the peripheral active patterns on the substrate; and
word lines disposed on the cell region of the substrate, extending in a first direction parallel to a top surface of the substrate, and spaced apart from each other in a second direction, the first and second directions parallel to a top surface of the substrate and crossing to each other,
wherein the bumper pattern has a line shape that extends in the second direction, and the word lines extend in the first direction to intersect the cell active patterns and the bumper pattern, and
wherein each of the word lines vertically overlaps the bumper pattern in a third direction perpendicular to the top surface of the substrate.
