Abstract
A semiconductor device includes a substrate including an active region, a word line structure, a bit line structure on the substrate, and a bit line contact pattern configured to electrically connect a first impurity region of the active region with the bit line structure. The device includes a storage node contact on a side wall of the bit line structure, and the storage node contact is electrically connected to a second impurity region of the active region. The device includes a spacer structure on a side wall of the bit line structure, the spacer structure on a side wall of the bit line contact pattern, the spacer structure including a lower spacer structure surrounding a side surface of the lower portion, and an upper spacer structure disposed on a side surface of the upper portion. The device includes a capacitor structure electrically connected to the storage node contact.
