Abstract
A semiconductor device comprises a lower structure; a plurality of semiconductor layers laterally oriented in a direction parallel to a surface of the lower structure; a plurality of bit lines connected an end of the semiconductor layers and extending in a direction perpendicular to the surface of the lower structure; word lines extending laterally in a direction crossing the semiconductor layers over the semiconductor layers; and a device isolation layer extending in the direction parallel to the surface of the lower structure to be disposed between the bit lines and the word lines and including air gaps.
