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 21):
A semi-conductor device, comprising:\n a dielectric layer having a first portion defining an empty region and a second portion defining a trench; first and second interconnects disposed within the empty region in the first portion and in the trench in the second portion, each of the first and second interconnects comprising metallic interconnect material and a liner disposed to surround portions of the metallic interconnect material; a self-forming layer, which is formed of chemical- and plasma-attack immune material, disposed on surfaces of the first and second interconnects in the first and second portions and on surfaces of the dielectric layer in the first portion; and a capping layer disposed on the dielectric layer to define air gaps with the self-forming layer in the first portion.
