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 16):
A method for forming a copper layer structure, comprising:\n providing a substrate comprising a circuit layer and a dielectric layer stacked on the circuit layer, wherein the dielectric layer has a via hole and a trench that is disposed over and communicates with the via hole, the via hole and the trench pass through the dielectric layer to expose a portion of the circuit layer, and the trench comprises a first portion, a second portion, and a third portion sequentially located over the via hole; plating a first copper layer filling the via hole and said first portion to form a via in the via hole; plating a carbon-containing copper layer on the first copper layer and filling said second portion; and plating a second copper layer on the carbon-containing copper layer and filling said third portion, wherein a carbon concentration of the via is substantially the same as a carbon concentration of the second copper layer.
