Abstract:
An etch back air gap (EBAG) process is provided. The EBAG process includes forming an initial structure that includes a dielectric layer disposed on a substrate and a liner disposed to line a trench defined in the dielectric layer. The process further includes impregnating a metallic interconnect material with dopant materials, filling a remainder of the trench with the impregnated metallic interconnect materials to form an intermediate structure and drive-out annealing of the intermediate structure. The drive-out annealing of the intermediate structure serves to drive the dopant materials out of the impregnated metallic interconnect materials and thereby forms a chemical- and plasma-attack immune material.

Claim (Index 18):
The EBAG process according to  claim 16 , wherein:\n the lining of the trench comprises chemical vapor deposition (CVD) processing of tantalum (Ta), tantalum nitride (TaN), cobalt (Co) or ruthenium (Ru), and the lining of the liner comprises atomic layer deposition (ALD) or CVD processing of manganese nitride (MnN).
