Abstract
A semiconductor device includes a pair of line patterns disposed on a substrate. A contact plug is disposed between the pair of line patterns and an air gap is disposed between the contact plug and the line patterns. A landing pad extends from a top end of the contact plug to cover a first part of the air gap and an insulating layer is disposed on a second part of the air gap, which is not covered by the landing pad.
