    摘要: A semiconductor device including vertical channel transistor and a method for forming the transistor, which can significantly decrease the resistance of a word line is provided. A vertical channel transistor includes a substrate including pillars each of which has a lower portion corresponding to a channel region. A gate insulation layer is formed over the substrate including the pillars. A metal layer having a low resistance is used for forming a surrounding gate electrode to decrease resistance of a word line. A barrier metal layer is formed between a gate insulation layer and a surrounding gate electrode so that deterioration of characteristics of the insulation layer is prevented. A world line is formed connecting gate electrodes formed over the barrier layer to surround the lower portion of each pillar.
