Abstract
A semiconductor device includes a word line extending in a first direction. A bit line extends on the word line in a second direction intersecting the first direction. A memory cell is disposed between the word line and the bit line. The memory cell includes a lower electrode, a selection element, and an upper electrode sequentially disposed on the word line. A filling pattern is on a side surface of the memory cell. An etch stop pattern includes an insulating material between the filling pattern and the bit line. A lower surface of the etch stop pattern is positioned at a higher level than a level of a lower surface of the upper electrode.
