A transistor which may effectively control the short channel effect with a vertical transistor structure. This structure may prevent the degradation of a transistor's performance caused by the hot carrier effect. The transistor has a source region having a concentration of implanted impurity ions on a semiconductor substrate; a channel region having a cylindrical shape over the source region; a drain region formed over the channel region; a gate insulation layer formed over the source region, a side of the channel region, and the drain region; and a gate conductor extending over an upper portion and one side of the channel region.
