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 9):
A method, comprising:\n forming a second dielectric layer over a first dielectric layer, the first dielectric layer having a first metal feature formed therein; forming a first opening and a second opening in the second dielectric layer; depositing a first protection layer in the first opening and a second protection layer in the second opening, the first protection layer lining the first opening and the second protection layer lining the second opening; depositing a first barrier layer in the first opening and a second barrier layer in the second opening, the first barrier layer lining the first protection layer in the first opening and the second barrier layer lining the second protection layer in the second opening; depositing a first conductive material in the first opening and the second opening to form a first metal line in the first opening and a second metal line in the second opening; etching the second dielectric layer to form an air gap trench interposed between the first metal line and the second metal line, the air gap trench having a first sidewall comprising a portion of the first protection layer and a second sidewall comprising a portion of the second protection layer; and depositing a third dielectric layer over the first dielectric layer to form an air gap between the first metal line and the second metal line.
