Abstract:
A semiconductor device includes an interlayer insulating layer including a first insulating layer on a substrate, and a plurality of interconnections in the first insulating layer. The interlayer insulating layer includes a first region, and a second region including an air gap. The air gap is defined between a pair of the interconnections in the second region. A top surface of the first insulating layer of the first region is lower than a top surface of at least one of the interconnections in the first region.

Claim (Index 1):
A semiconductor device comprising:\n an interlayer insulating layer including a first insulating layer on a substrate and a second insulating layer covering the first insulating layer; a plurality of interconnections in the first insulating layer; and a plurality of barrier patterns between the interlayer insulating layer and the interconnections, respectively, wherein each of the barrier patterns covers a bottom surface and both sidewalls of each of the interconnections, wherein the interlayer insulating layer includes a first region, and a second region including an air gap, wherein the air gap is between a pair of the interconnections in the second region, wherein each of the pair of interconnections includes a first portion adjacent to the air gap and a second portion in a central region adjacent to the first portion, wherein a top surface of the first portion is lower than a top surface of the barrier pattern on at least one of the sidewalls, wherein a top surface of the second portion is higher than a top surface of the first portion, wherein the top surface of the second portion is level with or lower than the top surface of the barrier pattern, wherein the second insulating layer covers a side surface of the barrier pattern and surrounds the air gap, wherein the second insulating layer has a first thickness on the side surface and a second thickness on the air gap, and wherein the second thickness is greater than the first thickness.
