Abstract: Methods of fabricating a memory device are provided. The methods may include forming a mask pattern including line-shaped portions that are parallel to each other and extend on a first region of a substrate. The mask pattern may extend on a second region of the substrate. The methods may also include forming word line regions in the first region using the mask pattern as a mask, forming word lines in the word line regions, respectively, and removing the mask pattern from the second region to expose the second region. The mask pattern may remain on the first region after removing the mask pattern from the second region. The methods may further include forming a channel epitaxial layer on the second region while using the mask pattern as a barrier to growth of the channel epitaxial layer on the first region.
