Abstract:
In a method for manufacturing an interconnect structure, a dielectric layer is removed to form a first recess and a second recess. The first recess is below the second recess. A first metal layer is deposited to fill the first recess and a first portion of the second recess. A carbon-containing layer is deposited over the first metal layer to fill a second portion of the second recess, which is over the first portion. A second metal layer is deposited over the carbon-containing layer to fill a third portion of the second recess, which is over the second portion. A carbon concentration of the carbon-containing layer is greater than a carbon concentration of the first metal layer and a carbon concentration of the second metal layer, and the carbon concentration of the first metal layer is substantially the same as the carbon concentration of the second metal layer.

Claim (Index 17):
The method of  claim 16 , wherein a ratio of a carbon concentration of the carbon-containing copper layer to the carbon concentration of the first copper layer or the carbon concentration of the second copper layer is greater than about 1.5.
