Abstract:
Provided herein is a semiconductor device including N stacked groups (where N is a natural number greater than or equal to two) sequentially stacked over a substrate, each stacked group including interlayer insulating films and conductive patterns alternately stacked, and N concave portions each having stepped sidewalls formed in the interlayer insulating films and the conductive patterns of the stacked groups, the N concave portions each having stepped sidewalls being aligned in a first direction.

Claim (Index 1):
A method of manufacturing a semiconductor device, comprising:\n sequentially stacking, on a substrate, N stacked groups (where N is a natural number of 2 or more) including first and second material films, which are alternately stacked; etching an uppermost N th  stacked group among the N stacked groups to form N first-type stepped structures, which are aligned in a first direction, in the N th  stacked group; forming a hole-type mask pattern including openings for exposing the N first-type stepped structures on the N stacked groups; and performing an etching process using the hole-type mask pattern as an etching barrier to form second-type stepped structures including multiple steps having height differences in the first direction and a second direction perpendicular to the first direction, wherein the hole-type mask pattern is formed to block a first stepped structure, which is adjacent to a memory array area of the N stacked groups, among the N first-type stepped structures, and to expose second to N th  stepped structures through the openings.
