    Abstract: Provided is a method of manufacturing a semiconductor device. The method includes forming isolated contact filling portions and an etch control portion, the isolated contact filling portions filling contact holes defined in a support layer and are spaced apart from each other in a first direction and a second direction perpendicular to the first direction and the etch control layer surrounding the isolated contact filling portions, forming an interconnection layer on the isolated contact filling portions and the etch control portion, and forming interconnection patterns by photo-etching the interconnection layer, the isolated contact patterns, and the etch control portion, the interconnection patterns being relatively narrow in the first direction and relatively wide in the second direction.

    Abstract: A method of manufacturing a semiconductor device includes: forming bit line structures spaced apart from each other by first groove disposed in first direction, extending in first direction, and spaced apart from each other in second direction perpendicular to first direction, on substrate in which word line is buried; forming multilayer spacer on both sidewalls of bit line structure; forming sacrificial layer to fill first groove; forming second grooves spaced apart from each other in first direction and second direction, by patterning sacrificial layer; etching outermost spacer of multilayer spacer located in second groove; forming first supplementary spacer in second groove; forming insulating layer to fill second groove; and forming third grooves spaced apart from each other in first direction and second direction, on both sides of first supplementary spacer, by removing sacrificial layer and insulating layer.
