Abstract
A semiconductor device includes a memory cell region. The memory cell region includes a memory stack structure including a first stack structure and a second stack structure; a plurality of channel structures vertically penetrating through the memory stack structure and connected to the second substrate; at least one first dummy structure; and at least one second dummy structure. At least a portion of the first dummy structure does not overlap the second dummy structure in a vertical direction.
