Abstract:
An interconnect layout structure, having a plurality of air gaps, includes a substrate having an insulating material disposed thereon and a conductive line disposed in the insulating material and extending along a first direction. The air gaps are formed in the insulating material and are arranged end-to-end along the first direction and immediately adjacent to a same side of the conductive line. A patterned hard mask is disposed on the conductive line and has a sidewall extending along a second direction that is perpendicular to the first direction and passing between the adjacent air gaps from the top view. A via structure is formed on the conductive line and is electrically connected to the conductive line.

Claim (Index 2):
The interconnect structure according to  claim 1 , wherein the insulating material comprises:\n a first insulating layer only on two sides of the conductive line; a second insulating layer on the first insulating layer, the patterned hard mask and the conductive line; and a third insulating layer on the second insulating material and covering the air gaps, wherein an etching rate of the second insulating layer is different from etching rates of the first insulating layer and the third insulating layer.
