    Abstract: A semiconductor device includes a bit line, a channel, a word line and a capacitor. The bit line is disposed on a substrate, and extends in a first direction substantially perpendicular to an upper surface of the substrate. The channel at least partially surrounds a sidewall of the bit line. The word line is disposed on the substrate, and at least a portion of the word line overlaps the channel in a horizontal direction substantially parallel to the upper surface of the substrate. The capacitor is electrically connected to the channel, and at least a portion of the capacitor overlaps the channel and the word line in the horizontal direction.
