Abstract:
A device comprises a first protection layer over sidewalls and a bottom of a first trench in a first dielectric layer, a first barrier layer over the first protection layer, a first metal line in the first trench, a second protection layer over sidewalls and a bottom of a second trench in the first dielectric layer, a second barrier layer over the second protection layer, a second metal line in the first trench, an air gap between the first trench and the second trench and a third protection layer over sidewalls of a third trench in the first dielectric layer, wherein the first protection layer, the second protection layer and the third protection are formed of a same material.

Claim (Index 15):
The method of  claim 9 , further comprising:\n prior to etching the second dielectric layer to form the air gap trench, depositing a hard mask layer over the second dielectric layer; and patterning the hard mask layer to expose the second dielectric layer between the first metal line and the second metal line, wherein etching the second dielectric to form the air gap trench comprises using the hard mask layer as an etch mask.
