Abstract:
An interconnect structure and a method of forming an interconnect structure are disclosed. The interconnect structure includes a lower etch stop layer (ESL); an upper low-k (LK) dielectric layer over the lower ESL; a first conductive feature in the upper LK dielectric layer, wherein the first conductive feature has a first metal line and a dummy via contiguous with the first metal line, the dummy via extending through the lower ESL; a first gap along an interface of the first conductive feature and the upper LK dielectric layer; and an upper ESL over the upper LK dielectric layer, the first conductive feature, and the first gap.

Claim (Index 13):
The interconnect structure of  claim 9 , further comprising:\n a second conductive feature extending completely through the second dielectric layer and the first ESL to a third conductive feature in the first dielectric layer; and a second air gap disposed between the second conductive feature and the second dielectric layer.
