Summary: | A semiconductor device includes a substrate including cell and core regions respectively having first and second active patterns having respective, opposing sidewall surfaces at least partially defining a trench therebetween, and a boundary region between the cell and core regions, a device isolation layer on the boundary region to fill the trench, a line structure on the first active pattern and extended from the cell region to the boundary region, and a capping pattern covering an end of the line structure on the boundary region. The device isolation layer includes one or more inner surfaces at least partially defining a recess region, which is adjacent to the end of the line structure, and the capping pattern is extended along the end of the line structure into the recess region. A top surface of the device isolation layer is between the line structure and a bottom surface of the capping pattern. |
