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 1):
A method comprising:\n forming a first trench, a second trench and a third trench in a first dielectric layer over a substrate; depositing a protection layer in the first trench, the second trench and the third trench; forming a via trench through the first dielectric layer at a bottom of the third trench; depositing a barrier layer in the first trench, the second trench, the third trench and the via trench; plating a first conductive material in the first trench, the second trench, the third trench and the via trench to form a first metal line in the first trench, a second metal line in the second trench, and a metal via extending from the via trench through the third trench; etching the first dielectric layer to form an air gap trench between the first metal line and the second metal line, wherein the air gap trench extends laterally from a sidewall of the protection layer in the first trench to a sidewall of the protection layer in the second trench; and depositing a second dielectric layer over the first dielectric layer to form an air gap between the first metal line and the second metal line.
