Abstract:
Three-dimensional (3D) semiconductor memory devices and methods of manufacturing the same are provided. Three-dimensional (3D) semiconductor memory devices may include a substrate including a cell array region and a connection region, a lower stack structure including a plurality of lower electrodes vertically stacked on the substrate, the lower stack structure having a first stair step structure extending in a first direction on the connection region and a second stair step structure extending in a second direction substantially perpendicular to the first direction on the connection region, and a plurality of intermediate stack structures vertically stacked on the lower stack structure. Each of the intermediate stack structures includes a plurality of intermediate electrodes vertically stacked and has a third stair step structure extending in the second direction on the connection region. Each of the intermediate stack structures exposes the third stair step structure of the intermediate stack structure disposed thereunder.

Claim (Index 1):
A three-dimensional (3D) semiconductor memory device comprising:\n a substrate comprising a cell array region and a connection region; a lower stack structure comprising a plurality of lower electrodes vertically stacked on the substrate, the lower stack structure comprising a first stair step structure extending in a first direction on the connection region and a second stair step structure extending in a second direction on the connection region, and the second direction being substantially perpendicular to the first direction; and a plurality of intermediate stack structures vertically stacked on the lower stack structure, each of the plurality of intermediate stack structures comprising a plurality of intermediate electrodes vertically stacked on the substrate, and each of the plurality of intermediate stack structures comprising a third stair step structure extending in the second direction on the connection region, wherein a slope of the first stair step structure has a first inclination angle with respect to a top surface of the substrate, wherein a slope of the second stair step structure has a second inclination angle with respect to the top surface of the substrate, wherein the plurality of intermediate stack structures comprise a fourth stair step structure extending in the first direction on the connection region, and a slope of the fourth stair step structure has a third inclination angle with respect to the top surface of the substrate, and wherein the third inclination angle is different from the first inclination angle, and the second inclination angle is substantially equal to the first inclination angle.
