    摘要: An integrated circuit device includes a device isolation pattern on a semiconductor substrate to define an active area therein. The active area includes a doped region therein. A conductive pattern extends on the active area and electrically contacts the doped region. The conductive pattern has a lower resistivity than the doped region. The conductive pattern may be disposed in a recessed region having a bottom surface lower than a top surface of the active area. A channel pillar electrically contacts to the doped region and extends therefrom in a direction away from the substrate. A conductive gate electrode is disposed on a sidewall of the channel pillar, and a gate dielectric layer is disposed between the gate electrode and the sidewall of the channel pillar.

    摘要: A vertical pillar transistor may include a plurality of lower pillars, a plurality of upper pillars, a first insulation part, a second insulation part and a word line. The plurality of lower pillars protrudes substantially perpendicular to a substrate and is defined by a plurality of trenches. The plurality of lower pillars extends along a second direction and may be separated from each other along a first direction substantially perpendicular to the second direction. The plurality of upper pillars may be formed on the plurality of lower pillars. The plurality of upper pillars has a width substantially smaller than that of the plurality of lower pillars. The first insulation part has a substantially uniform thickness on a sidewall of each of the plurality of lower pillars. The second insulation part may be formed on the first insulation part to fill a gap between the adjacent upper pillars. The word line may be formed on the second insulation part and may extend between facing sidewalls of the adjacent pair of upper pillars along the first direction.
