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 10):
The method of  claim 9 , further comprising:\n prior to depositing the first protection layer, forming a third opening in the second dielectric layer; depositing a third protection layer in the third opening, the third protection layer linking the third opening; extending a bottom of the third opening to expose the first metal feature; depositing a third barrier layer in the extended third opening, the third barrier layer lining the third protection layer in an upper portion of the third opening, the third barrier layer lining the second dielectric layer in an extended portion of the third opening; and depositing the first conductive material in the extended third opening to form a first metal via in the extended third opening.
