    Abstract: A semiconductor device includes a vertical channel transistor including a vertical channel region extending in a vertical direction and a cell gate electrode facing a first side surface of the vertical channel region. A bit line is electrically connected to the vertical channel transistor at a level that is lower than a level of the vertical channel transistor. A peripheral semiconductor body has at least a portion thereof disposed on a same level as the vertical channel region. Peripheral source/drain regions are disposed in the peripheral semiconductor body and are spaced apart from each other in a horizontal direction. A peripheral channel region is disposed between the peripheral source/drain regions in the peripheral semiconductor body. A peripheral gate is disposed below the peripheral semiconductor body. At least a portion of the peripheral gate is disposed on a same level as at least a portion of the bit line.

    Abstract: A semiconductor device may include first pillar insulation patterns on a substrate, second pillar insulation patterns on the substrate, silicon patterns stacked on the substrate to be spaced apart from each other in a vertical direction, a word line on each of upper and lower surfaces of each silicon pattern, a bit line contacting a first sidewall of at least a first silicon pattern of the silicon patterns, and a capacitor contacting a second sidewall of the first silicon pattern. Each of the first pillar insulation patterns may extend in the vertical direction from an upper surface of the substrate. The first pillar insulation patterns may be spaced apart from each other in a first direction, and may be aligned in a line. Each of the second pillar insulation patterns may extend in the vertical direction. The second pillar insulation patterns may be spaced apart from each other in the first direction, and may be aligned in a line. The second pillar insulation patterns and the first pillar insulation patterns may overlap with each other in a second direction perpendicular to the first direction. Each of the silicon patterns may extend in the second direction and be positioned between two first pillar insulation patterns and between two second pillar insulation patterns, and each of the silicon patterns may include two sidewalls opposite each other in the first direction and having a straight line shape. Each word line may extend in the first direction to cross the silicon patterns. Each word line may contact a sidewall of at least one insulation pattern of the first pillar insulation patterns and/or at least one insulation pattern of the second pillar insulation patterns. The bit line may extend in the vertical direction. The capacitor may be disposed in a horizontal direction to have a dielectric layer horizontally between a lower electrode and an upper electrode.
