Abstract:
A method of forming a semiconductor structure includes providing a substrate; forming a low-k dielectric layer over the substrate; embedding a conductive wiring into the low-k dielectric layer; and thermal soaking the conductive wiring in a carbon-containing silane-based chemical to form a barrier layer on the conductive wiring. A lining barrier layer is formed in the opening for embedding the conductive wiring. The lining barrier layer may comprise same materials as the barrier layer, and the lining barrier layer may be recessed before forming the barrier layer and may contain a metal that can be silicided.

Claim (Index 8):
A semiconductor device comprising:\n a conductive material extending into a dielectric layer, the conductive material comprising a first element; a first barrier layer lining sidewalls of the conductive material, the first barrier layer comprising a second element different from the first element; and a second barrier layer over the conductive material and the first barrier layer, the second barrier layer comprising:\n a first region in physical contact with the conductive material, the first region comprising a silicide of the first element, the first region having a first thickness; and \n a second region in physical contact with the first barrier layer, the second region comprising a silicide of the second element, the second region having a second thickness different from the first thickness.
