Abstract

See full text

A method of manufacturing an integrated circuit device includes forming multilayered stack structures that extend parallel to and separated from one another on a substrate, followed by forming a buried conductive layer including a plurality of conductive line patterns that extend parallel to an extending direction of the multilayered stack structures and alternate with the multilayered stack structures; removing portions of the buried conductive layer to thereby separate the plurality of conductive line patterns of the buried conductive layer from one another as a plurality of contact plugs and, at the same time, form a plurality of insulating fence spaces that alternate with the plurality of contact plugs in the extending direction of the multilayered stack structures; and forming a plurality of insulating fences that fill the plurality of insulating fence spaces and include a plurality of insulating line patterns extending parallel to one another.
