Patent ID: 11903187
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a substrate including a cell region, a peripheral region, and a boundary region dividing the cell region from the peripheral region, wherein the boundary region has a boundary trench between the cell region from the peripheral region;
cell active patterns on the cell region of the substrate;
peripheral active patterns on the peripheral region of the substrate;
a boundary insulating pattern disposed in the boundary trench and disposed between the cell active patterns and the peripheral active patterns;
a bumper pattern disposed on the cell region of the substrate and extending along the boundary insulating pattern between the boundary insulating pattern and the cell active patterns; and
word lines disposed on the cell region of the substrate, extending in a first direction, 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 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,
wherein each of the word lines vertically overlaps the bumper pattern in a third direction perpendicular to the top surface of the substrate, and
wherein a width of the bumper pattern in the first direction is greater than a width of each of the cell active patterns in the first direction.
