Abstract

See full text

Disclosed is a three-dimensional semiconductor device comprising channel regions that penetrate the stack structure and extend in a direction perpendicular to a top surface of the first substrate, a first interlayer dielectric layer on the stack structure, and a peripheral circuit structure on the first interlayer dielectric layer. The peripheral circuit structure includes peripheral circuit elements on a first surface of a second substrate. The peripheral circuit elements are electrically connected to the channel regions and at least one of the gate electrodes. The first substrate has a first crystal plane parallel to the top surface thereof. The second substrate has a second crystal plane parallel to the first surface thereof. An arrangement direction of atoms of the first crystal plane intersects an arrangement direction of atoms of the second crystal plane.
