The stacked structure is etched to form a stacked structure pattern of a mask insulation layer pattern, the gate electrode and a gate insulation layer pattern(13) by using a gate electrode mask as an etch mask. An insulation layer spacer(19) is formed on the sidewall of the stacked structure pattern, and impurity ions are implanted into the substrate at both sides of the insulation layer spacer to form a junction region. A polycrystalline silicon layer is formed on the resultant structure, and is planarized to form a contact plug coupled to the junction region. A conductive layer is formed on the resultant structure. The conductive layer is etched to form a bitline pillar(23b) of a protruded pillar type coupled to the contact plug by using a bitline contact mask as an etch mask such that the bitline contact mask protects a portion predetermined as a bitline contact of the contact plug. An interlayer dielectric is formed on the resultant structure, and is planarized to expose the bitline pillar. A bitline coupled to the bitline pillar is formed.
