Abstract: According to some embodiments, a semiconductor device may include gate structures on a substrate; first and second impurity regions formed in the substrate and at both sides of each of the gate structures; conductive line structures provided to cross the gate structures and connected to the first impurity regions; and contact plugs connected to the second impurity regions, respectively. For each of the conductive line structures, the semiconductor device may include a first air spacer provided on a sidewall of the conductive line structure; a first material spacer provided between the conductive line structure and the first air spacer; and an insulating pattern provided on the air spacer. The insulating pattern may include a first portion and a second portion, and the second portion may have a depth greater than that of the first portion and defines a top surface of the air spacer.
